Motorised throttle self-compensation fault
AI status
Completed
Completed
100%
Causes
- Throttle body actuator (motor) fault
- Throttle position sensor (TPS) or potentiometer fault
- Carbon/soot buildup causing mechanical binding
- Wiring harness open, short or poor connection at throttle body
- Poor power supply or ground to throttle actuator
- Failed or out-of-date engine control module (ECU) software or corruption
Symptoms
- Malfunction Indicator Lamp (MIL/Check Engine) illuminated
- Reduced engine power or limp-home mode
- Erratic or poor idle, hunting idle speed
- Delayed or unresponsive accelerator pedal input
- Engine stalling at idle or during low-speed maneuvers
- Throttle angle reported not matching pedal command in live data
What to check
- Read stored DTCs and freeze frame data with a compatible diagnostic tool
- Check for additional related codes (TPS, actuator, communication, power/ground)
- Inspect throttle body and connector for dirt, carbon, corrosion, water ingress or physical damage
- Compare commanded throttle angle vs actual throttle angle in live data during key-on and while cranking/running
- Backprobe and measure actuator supply voltage and ground with key ON (expected battery voltage at supply pin)
- Check throttle position sensor voltages/outputs at closed and wide-open throttle against manufacturer specs
Signal parameters
- Throttle position sensor typical range: approx. 0.5–4.5 V (closed to wide-open) — check OEM spec
- Closed-throttle TPS voltage typically ~0.5–1.0 V (vehicle-specific)
- Actuator supply: battery voltage (~11–14.5 V) at rest/ignition on
- Actuator control: PWM signal from ECU — frequency often in the 100–400 Hz range (manufacturer-specific)
- Actuator current: can draw up to a few amps during operation (measure with appropriate ammeter)
- Commanded vs actual throttle angle: command should track actual within a few degrees during calibration — refer to service values
Diagnostic algorithm
- Connect a professional scan tool, record live data, freeze frame and all related DTCs.
- Verify battery voltage and charging system; low battery can prevent calibration. Recharge or replace battery if necessary.
- Inspect throttle body assembly: remove intake ducting and visually check for heavy carbon, binding or foreign objects; clean per service procedure if needed.
- With ignition ON (engine OFF) compare commanded throttle angle vs actual angle in live data. Attempt an ECU-initiated throttle self-test (if available) and observe response.
- Backprobe actuator connector: measure power supply (should be battery voltage), ground continuity, and control signal (PWM) while commanding throttle. Note any missing or abnormal signals.
- Check TPS outputs across travel for smooth, monotonic change with no steps or dropouts. Replace TPS/throttle body if readings are erratic or out of spec.
- Perform wiring checks: continuity, insulation resistance and connector pin integrity between throttle body and ECU. Repair any damaged wiring or corroded terminals.
- Clear codes and perform throttle adaptation/relearn procedure per manufacturer instructions. Attempt drive/idle relearn and re-test.
- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
- If actuator and wiring test good, consider ECU software update or ECU as potential cause — consult factory service information before replacement.
Likely causes
- Throttle actuator motor is weak, seized or electrically intermittent
- Throttle body mechanically binding from carbon deposits or foreign object
- Corroded/loose connector or broken wire in actuator/TPS harness
- TPS signal out of range or intermittent causing calibration failure
- Battery/charging low or poor ground under calibration attempt
- ECU failed to complete adaptation due to missing relearn or software issue
Fault status
Status
Motorised throttle self-compensation fault — ECU unable to complete throttle actuator calibration or compensate actual position.
Repair difficulty: Medium
Diagnostic time: 1-3 hours

- Read stored DTCs and freeze frame data with a compatible diagnostic tool
- Check for additional related codes (TPS, actuator, communication, power/ground)
- Inspect throttle body and connector for dirt, carbon, corrosion, water ingress or physical damage
- Compare commanded throttle angle vs actual throttle angle in live data during key-on and while cranking/running
- Backprobe and measure actuator supply voltage and ground with key ON (expected battery voltage at supply pin)
- Check throttle position sensor voltages/outputs at closed and wide-open throttle against manufacturer specs
Signal parameters
- Throttle position sensor typical range: approx. 0.5–4.5 V (closed to wide-open) — check OEM spec
- Closed-throttle TPS voltage typically ~0.5–1.0 V (vehicle-specific)
- Actuator supply: battery voltage (~11–14.5 V) at rest/ignition on
- Actuator control: PWM signal from ECU — frequency often in the 100–400 Hz range (manufacturer-specific)
- Actuator current: can draw up to a few amps during operation (measure with appropriate ammeter)
- Commanded vs actual throttle angle: command should track actual within a few degrees during calibration — refer to service values
Diagnostic algorithm
- Connect a professional scan tool, record live data, freeze frame and all related DTCs.
- Verify battery voltage and charging system; low battery can prevent calibration. Recharge or replace battery if necessary.
- Inspect throttle body assembly: remove intake ducting and visually check for heavy carbon, binding or foreign objects; clean per service procedure if needed.
- With ignition ON (engine OFF) compare commanded throttle angle vs actual angle in live data. Attempt an ECU-initiated throttle self-test (if available) and observe response.
- Backprobe actuator connector: measure power supply (should be battery voltage), ground continuity, and control signal (PWM) while commanding throttle. Note any missing or abnormal signals.
- Check TPS outputs across travel for smooth, monotonic change with no steps or dropouts. Replace TPS/throttle body if readings are erratic or out of spec.
- Perform wiring checks: continuity, insulation resistance and connector pin integrity between throttle body and ECU. Repair any damaged wiring or corroded terminals.
- Clear codes and perform throttle adaptation/relearn procedure per manufacturer instructions. Attempt drive/idle relearn and re-test.
- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
- If actuator and wiring test good, consider ECU software update or ECU as potential cause — consult factory service information before replacement.
Likely causes
- Throttle actuator motor is weak, seized or electrically intermittent
- Throttle body mechanically binding from carbon deposits or foreign object
- Corroded/loose connector or broken wire in actuator/TPS harness
- TPS signal out of range or intermittent causing calibration failure
- Battery/charging low or poor ground under calibration attempt
- ECU failed to complete adaptation due to missing relearn or software issue
Fault status
Status

- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
- If actuator and wiring test good, consider ECU software update or ECU as potential cause — consult factory service information before replacement.
Likely causes
- Throttle actuator motor is weak, seized or electrically intermittent
- Throttle body mechanically binding from carbon deposits or foreign object
- Corroded/loose connector or broken wire in actuator/TPS harness
- TPS signal out of range or intermittent causing calibration failure
- Battery/charging low or poor ground under calibration attempt
- ECU failed to complete adaptation due to missing relearn or software issue
Fault status

Causes
- Throttle body actuator (motor) fault
- Throttle position sensor (TPS) or potentiometer fault
- Carbon/soot buildup causing mechanical binding
- Wiring harness open, short or poor connection at throttle body
- Poor power supply or ground to throttle actuator
- Failed or out-of-date engine control module (ECU) software or corruption
Symptoms
- Malfunction Indicator Lamp (MIL/Check Engine) illuminated
- Reduced engine power or limp-home mode
- Erratic or poor idle, hunting idle speed
- Delayed or unresponsive accelerator pedal input
- Engine stalling at idle or during low-speed maneuvers
- Throttle angle reported not matching pedal command in live data
What to check
- Read stored DTCs and freeze frame data with a compatible diagnostic tool
- Check for additional related codes (TPS, actuator, communication, power/ground)
- Inspect throttle body and connector for dirt, carbon, corrosion, water ingress or physical damage
- Compare commanded throttle angle vs actual throttle angle in live data during key-on and while cranking/running
- Backprobe and measure actuator supply voltage and ground with key ON (expected battery voltage at supply pin)
- Check throttle position sensor voltages/outputs at closed and wide-open throttle against manufacturer specs
Signal parameters
- Throttle position sensor typical range: approx. 0.5–4.5 V (closed to wide-open) — check OEM spec
- Closed-throttle TPS voltage typically ~0.5–1.0 V (vehicle-specific)
- Actuator supply: battery voltage (~11–14.5 V) at rest/ignition on
- Actuator control: PWM signal from ECU — frequency often in the 100–400 Hz range (manufacturer-specific)
- Actuator current: can draw up to a few amps during operation (measure with appropriate ammeter)
- Commanded vs actual throttle angle: command should track actual within a few degrees during calibration — refer to service values
Diagnostic algorithm
- Connect a professional scan tool, record live data, freeze frame and all related DTCs.
- Verify battery voltage and charging system; low battery can prevent calibration. Recharge or replace battery if necessary.
- Inspect throttle body assembly: remove intake ducting and visually check for heavy carbon, binding or foreign objects; clean per service procedure if needed.
- With ignition ON (engine OFF) compare commanded throttle angle vs actual angle in live data. Attempt an ECU-initiated throttle self-test (if available) and observe response.
- Backprobe actuator connector: measure power supply (should be battery voltage), ground continuity, and control signal (PWM) while commanding throttle. Note any missing or abnormal signals.
- Check TPS outputs across travel for smooth, monotonic change with no steps or dropouts. Replace TPS/throttle body if readings are erratic or out of spec.
- Perform wiring checks: continuity, insulation resistance and connector pin integrity between throttle body and ECU. Repair any damaged wiring or corroded terminals.
- Clear codes and perform throttle adaptation/relearn procedure per manufacturer instructions. Attempt drive/idle relearn and re-test.
- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
- If actuator and wiring test good, consider ECU software update or ECU as potential cause — consult factory service information before replacement.

Causes
- Throttle body actuator (motor) fault
- Throttle position sensor (TPS) or potentiometer fault
- Carbon/soot buildup causing mechanical binding
- Wiring harness open, short or poor connection at throttle body
- Poor power supply or ground to throttle actuator
- Failed or out-of-date engine control module (ECU) software or corruption
Symptoms
- Malfunction Indicator Lamp (MIL/Check Engine) illuminated
- Reduced engine power or limp-home mode
- Erratic or poor idle, hunting idle speed
- Delayed or unresponsive accelerator pedal input
- Engine stalling at idle or during low-speed maneuvers
- Throttle angle reported not matching pedal command in live data
What to check
- Read stored DTCs and freeze frame data with a compatible diagnostic tool
- Check for additional related codes (TPS, actuator, communication, power/ground)
- Inspect throttle body and connector for dirt, carbon, corrosion, water ingress or physical damage
- Compare commanded throttle angle vs actual throttle angle in live data during key-on and while cranking/running
- Backprobe and measure actuator supply voltage and ground with key ON (expected battery voltage at supply pin)
- Check throttle position sensor voltages/outputs at closed and wide-open throttle against manufacturer specs
Signal parameters
- Throttle position sensor typical range: approx. 0.5–4.5 V (closed to wide-open) — check OEM spec
- Closed-throttle TPS voltage typically ~0.5–1.0 V (vehicle-specific)
- Actuator supply: battery voltage (~11–14.5 V) at rest/ignition on
- Actuator control: PWM signal from ECU — frequency often in the 100–400 Hz range (manufacturer-specific)
- Actuator current: can draw up to a few amps during operation (measure with appropriate ammeter)
- Commanded vs actual throttle angle: command should track actual within a few degrees during calibration — refer to service values

- Connect a professional scan tool, record live data, freeze frame and all related DTCs.
- Verify battery voltage and charging system; low battery can prevent calibration. Recharge or replace battery if necessary.
- Inspect throttle body assembly: remove intake ducting and visually check for heavy carbon, binding or foreign objects; clean per service procedure if needed.
- With ignition ON (engine OFF) compare commanded throttle angle vs actual angle in live data. Attempt an ECU-initiated throttle self-test (if available) and observe response.
- Backprobe actuator connector: measure power supply (should be battery voltage), ground continuity, and control signal (PWM) while commanding throttle. Note any missing or abnormal signals.
- Check TPS outputs across travel for smooth, monotonic change with no steps or dropouts. Replace TPS/throttle body if readings are erratic or out of spec.
- Perform wiring checks: continuity, insulation resistance and connector pin integrity between throttle body and ECU. Repair any damaged wiring or corroded terminals.
- Clear codes and perform throttle adaptation/relearn procedure per manufacturer instructions. Attempt drive/idle relearn and re-test.
- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
- If actuator and wiring test good, consider ECU software update or ECU as potential cause — consult factory service information before replacement.
Likely causes
- Throttle actuator motor is weak, seized or electrically intermittent
- Throttle body mechanically binding from carbon deposits or foreign object
- Corroded/loose connector or broken wire in actuator/TPS harness
- TPS signal out of range or intermittent causing calibration failure
- Battery/charging low or poor ground under calibration attempt
- ECU failed to complete adaptation due to missing relearn or software issue

- Closed-throttle TPS voltage typically ~0.5–1.0 V (vehicle-specific)
- Actuator supply: battery voltage (~11–14.5 V) at rest/ignition on
- Actuator control: PWM signal from ECU — frequency often in the 100–400 Hz range (manufacturer-specific)
- Actuator current: can draw up to a few amps during operation (measure with appropriate ammeter)
- Commanded vs actual throttle angle: command should track actual within a few degrees during calibration — refer to service values
Diagnostic algorithm
- Connect a professional scan tool, record live data, freeze frame and all related DTCs.
- Verify battery voltage and charging system; low battery can prevent calibration. Recharge or replace battery if necessary.
- Inspect throttle body assembly: remove intake ducting and visually check for heavy carbon, binding or foreign objects; clean per service procedure if needed.
- With ignition ON (engine OFF) compare commanded throttle angle vs actual angle in live data. Attempt an ECU-initiated throttle self-test (if available) and observe response.
- Backprobe actuator connector: measure power supply (should be battery voltage), ground continuity, and control signal (PWM) while commanding throttle. Note any missing or abnormal signals.
- Check TPS outputs across travel for smooth, monotonic change with no steps or dropouts. Replace TPS/throttle body if readings are erratic or out of spec.
- Perform wiring checks: continuity, insulation resistance and connector pin integrity between throttle body and ECU. Repair any damaged wiring or corroded terminals.
- Clear codes and perform throttle adaptation/relearn procedure per manufacturer instructions. Attempt drive/idle relearn and re-test.
- If problem persists, substitute a known-good throttle body or actuator (if available) or send throttle body for bench testing per service manual.
