Completed
100%
Causes
- Throttle body plate binding due to carbon or deposits
- Broken or bent throttle plate shaft or linkage
- Debris or foreign object physically blocking throttle movement
- Faulty throttle body actuator (motor/gears)
- Worn or damaged throttle body bearings
- Faulty throttle position sensor(s) or accelerator pedal sensors causing incorrect feedback
Symptoms
- Check Engine Light (MIL) illuminated
- Reduced engine power / limp-home mode
- Poor or delayed throttle response and hesitation
- Unstable idle or stalling at low RPM
- Throttle position shown by scan tool does not follow commanded/target values
- Multiple throttle-related codes stored or intermittent faults
What to check
- Obtain full symptom history and freeze frame data with a professional scan tool
- Read and record all stored and pending DTCs and live data (throttle target vs actual, pedal position)
- Visually inspect throttle body for carbon/deposits, debris or physical damage
- Inspect wiring harness and connectors for the throttle body and accelerator pedal sensors for corrosion, bent pins, damage or loose connections
- With ignition ON (engine off) command throttle open/close using a diagnostic tool and observe movement and listen for abnormal noises
- Check battery voltage and power supply to throttle actuator during diagnostics
Signal parameters
- Commanded (target) throttle position (%) vs actual throttle position (%)
- Throttle position sensor voltage(s) or % from TPS channels (where applicable)
- Accelerator pedal position sensor voltages and correlation (APPS1/APPS2)
- Actuator motor supply voltage (battery voltage present at connector with key on)
- Actuator motor ground continuity and resistance
- Actuator motor current draw (A) during commanded movement
Diagnostic algorithm
- Connect a capable scan tool and record all throttle- and pedal-related DTCs and freeze-frame data
- Review live data: compare commanded throttle position to actual position and accelerator pedal input; note discrepancies
- Attempt a throttle actuate / perform throttle body self-test from the scan tool and observe movement, sound and actual vs commanded values
- If the throttle does not move or binds: remove intake ducting and visually inspect throttle plate bore for carbon, gum, or foreign objects; clean if contamination is present using appropriate throttle-body cleaner and safe procedure
- Manually operate the throttle plate (where service manual allows) to check for smooth travel and binding; do not force parts beyond intended movement
- Inspect and test wiring and connectors: check for 12V supply and ground continuity to the actuator, test signal wires and check for damaged insulation or corrosion
- Measure actuator motor current while commanding movement — unusually high current indicates mechanical binding or internal gear failure
- Check accelerator pedal position sensor correlation; replace or repair if inconsistent with pedal input
- Perform throttle adaptation/relearn sequence per BMW service procedure after cleaning or replacing components; clear codes and retest road/scan tool data
- If mechanical binding persists after cleaning and wiring checks, replace the throttle body assembly (or actuator) and retest
- After repair, clear codes, perform adaptation, and verify normal response under a range of operating conditions; recheck for related codes
Likely causes
- Carbon or dirt buildup on throttle plate preventing full travel
- Throttle body actuator motor or internal gear failure
- Mechanical damage to shaft/plate or foreign object lodged in bore
- Wiring/connector issue causing actuator to lose power or signal
- Sensor mismatch/correlation fault causing DME to determine valve is stuck
Fault status
Status
Throttle valve mechanically stuck: engine control detected the throttle plate is not following commanded position (binding or blocked), so torque/power may be reduced and fault stored.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3 hours

- Manually operate the throttle plate (where service manual allows) to check for smooth travel and binding; do not force parts beyond intended movement
- Inspect and test wiring and connectors: check for 12V supply and ground continuity to the actuator, test signal wires and check for damaged insulation or corrosion
- Measure actuator motor current while commanding movement — unusually high current indicates mechanical binding or internal gear failure
- Check accelerator pedal position sensor correlation; replace or repair if inconsistent with pedal input
- Perform throttle adaptation/relearn sequence per BMW service procedure after cleaning or replacing components; clear codes and retest road/scan tool data
- If mechanical binding persists after cleaning and wiring checks, replace the throttle body assembly (or actuator) and retest
- After repair, clear codes, perform adaptation, and verify normal response under a range of operating conditions; recheck for related codes
Likely causes
- Carbon or dirt buildup on throttle plate preventing full travel
- Throttle body actuator motor or internal gear failure
- Mechanical damage to shaft/plate or foreign object lodged in bore
- Wiring/connector issue causing actuator to lose power or signal
- Sensor mismatch/correlation fault causing DME to determine valve is stuck
Fault status
Status
Throttle valve mechanically stuck: engine control detected the throttle plate is not following commanded position (binding or blocked), so torque/power may be reduced and fault stored.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3 hours

- Read and record all stored and pending DTCs and live data (throttle target vs actual, pedal position)
- Visually inspect throttle body for carbon/deposits, debris or physical damage
- Inspect wiring harness and connectors for the throttle body and accelerator pedal sensors for corrosion, bent pins, damage or loose connections
- With ignition ON (engine off) command throttle open/close using a diagnostic tool and observe movement and listen for abnormal noises
- Check battery voltage and power supply to throttle actuator during diagnostics
Signal parameters
- Commanded (target) throttle position (%) vs actual throttle position (%)
- Throttle position sensor voltage(s) or % from TPS channels (where applicable)
- Accelerator pedal position sensor voltages and correlation (APPS1/APPS2)
- Actuator motor supply voltage (battery voltage present at connector with key on)
- Actuator motor ground continuity and resistance
- Actuator motor current draw (A) during commanded movement
Diagnostic algorithm
- Connect a capable scan tool and record all throttle- and pedal-related DTCs and freeze-frame data
- Review live data: compare commanded throttle position to actual position and accelerator pedal input; note discrepancies
- Attempt a throttle actuate / perform throttle body self-test from the scan tool and observe movement, sound and actual vs commanded values
- If the throttle does not move or binds: remove intake ducting and visually inspect throttle plate bore for carbon, gum, or foreign objects; clean if contamination is present using appropriate throttle-body cleaner and safe procedure
- Manually operate the throttle plate (where service manual allows) to check for smooth travel and binding; do not force parts beyond intended movement
- Inspect and test wiring and connectors: check for 12V supply and ground continuity to the actuator, test signal wires and check for damaged insulation or corrosion
- Measure actuator motor current while commanding movement — unusually high current indicates mechanical binding or internal gear failure
- Check accelerator pedal position sensor correlation; replace or repair if inconsistent with pedal input
- Perform throttle adaptation/relearn sequence per BMW service procedure after cleaning or replacing components; clear codes and retest road/scan tool data
- If mechanical binding persists after cleaning and wiring checks, replace the throttle body assembly (or actuator) and retest
- After repair, clear codes, perform adaptation, and verify normal response under a range of operating conditions; recheck for related codes
Likely causes
- Carbon or dirt buildup on throttle plate preventing full travel
- Throttle body actuator motor or internal gear failure
- Mechanical damage to shaft/plate or foreign object lodged in bore
- Wiring/connector issue causing actuator to lose power or signal
- Sensor mismatch/correlation fault causing DME to determine valve is stuck
Fault status
Status
Throttle valve mechanically stuck: engine control detected the throttle plate is not following commanded position (binding or blocked), so torque/power may be reduced and fault stored.
Repair difficulty: Medium
Diagnostic time: 1.5 - 3 hours
