Causes

Faulty throttle actuator assembly (motor, gears, or internal controller)
Poor power supply or low battery voltage to the throttle/ECM
Corroded, loose, damaged or shorted wiring/connectors to the throttle actuator or ECM
Poor or intermittent ground(s)
Faulty ECM/PCM or internal module failure
Contaminated or mechanically sticking throttle plate

Symptoms

Malfunction Indicator Lamp (MIL) / Check Engine Light illuminated
Reduced engine power / “limp” mode (reduced throttle response)
Unresponsive or delayed throttle/pedal response
Engine surging, rough idle, or stalling at idle
Stored ETC or throttle-related codes in addition to P061F

What to check

Read all stored/active DTCs and freeze frame data with a capable scanner
Record battery voltage at key-on and while cranking/running (should be ~12.4–14.7 V nominal)
Visually inspect throttle body connector, wiring harness, and ECM connector for damage, corrosion, or water intrusion
Check and secure engine ground points related to ECM/throttle body
Verify pedal position sensor signals and compare to throttle position sensor values using live data
Attempt an active test (commanded throttle open/close) with a scan tool and observe response and any error messages

Signal parameters

Battery supply to throttle/ECM: ~12–14.7 V (vehicle dependent)
Throttle position sensor (TPS) idle voltage: approximately 0.5–1.5 V; full open about 3.5–4.5 V (values vary by make)
Pedal position sensor (APP) outputs should correlate to TPS and change smoothly with pedal travel
Throttle motor control: duty cycle or PWM command from ECM; observe changes when commanding open/close
Throttle plate angle: should move within expected degrees when commanded; response time should be quick and smooth

Diagnostic algorithm

Retrieve all DTCs, freeze frame and live data. Note battery voltage and engine conditions when the code set.
Inspect wiring and connectors to the throttle body and ECM for damage, corrosion, or poor pins. Repair any physical damage.
Check battery and charging system; ensure stable supply voltage during tests. Charge or replace battery if low.
Clear codes and attempt to reproduce fault while monitoring TPS, APP and throttle motor command (duty/current) with a scan tool.
Perform an active throttle control test (open/close) from the scanner. Verify throttle plate movement and compare commanded vs actual positions.
If feedback signals (TPS/APP) do not match commands, isolate with backprobe tests: verify power, ground and signal continuity between throttle body and ECM.
If wiring and power/grounds are good but internal throttle controller still fails or reports internal errors, check for available software updates or reflash ECM/throttle body module per manufacturer procedures.
If module reflash is not available or fails to clear fault and all electrical/mechanical checks are good, consider replacing the throttle actuator assembly or ECM per vehicle-specific diagnostics. After repairs, perform relearn/calibration procedures and verify repair by road test.
Document findings and advise customer of any replaced modules and required programming or adaptations.

Likely causes

Damaged throttle actuator control module inside the throttle body
Open/short in power or ground circuit to the throttle actuator
Faulty throttle position sensor(s) or pedal position sensor causing inconsistent feedback
Battery/charging system voltage below acceptable threshold during operation
Corrosion or poor connector pin contact at throttle body or ECM

Fault status

⚠️ Status

Internal Control Module Throttle Actuator Controller Performance — ETC subsystem not performing within expected parameters; check throttle actuator, power/grounds, wiring, sensors, and module software.
