Causes

  • Internal PCM/ECM hardware or software fault
  • Corrupted or incomplete module programming/firmware
  • Intermittent or low battery/poor battery voltage during key-on or programming
  • Poor power or ground to the control module
  • CAN bus/communication errors or short to voltage/ground
  • Damaged, corroded, or loose PCM connector pins

Symptoms

  • Malfunction Indicator Lamp (MIL) illuminated
  • Reduced engine power / 'limp' or fail-safe mode
  • Erratic or no throttle response to accelerator pedal
  • Delayed or inconsistent acceleration
  • Stored multiple related codes (APP, throttle actuator, communication faults)
  • Vehicle may hesitate to start or may not move under throttle command

What to check

  • Read and record all stored codes and freeze frame data with a full-function scan tool
  • Check battery voltage and charging system (battery should be >=12.4 V at rest; >=13.5 V with engine running)
  • Inspect PCM connector and harness for corrosion, bent pins, water intrusion, or damage
  • Check main PCM power and ground circuits for correct voltage and good resistance to chassis/negative
  • Verify CAN bus integrity and look for other modules showing communication errors
  • Check APP sensor voltages and correlation between sensor channels with key on and while pressing the pedal

Signal parameters

  • APP sensor typical idle voltage: ~0.2–1.0 V (sensor 1) and complementary sensor often ~4.0–4.8 V (sensor 2) at rest — values vary by vehicle
  • APP sensor range through travel: ~0.5–4.5 V (increasing or inverse depending on sensor)
  • APP sensors must change smoothly and proportionally; no dropouts, spikes, or flat spots
  • CAN High/Low idle differential: typically around 0 V differential relative to midpoint (nominal CAN voltages ~2.5 V each), no bus short to battery or ground
  • PCM supply voltage: stable near battery voltage on key ON; no large transients during operation or programming

Diagnostic algorithm

  1. Retrieve freeze frame and all related/continuous codes; note conditions when P060D set.
  2. Verify battery state of charge and charging system. Charge or replace battery if weak; retest.
  3. Inspect PCM connector and harness for corrosion, loose pins, water intrusion, or damaged wires. Repair any faults.
  4. Verify PCM power and ground circuits. Measure voltage at PCM supply pins with key ON and compare to battery. Repair poor power/ground if found.
  5. Check APP sensor signals with a lab-grade DVOM or scope: measure voltages on each sensor channel at rest and while operating pedal. Confirm proper idle and full-travel voltages and that two channels correlate (no identical signals unless specified by manufacturer).
  6. Scan for CAN/communication faults and verify other modules are communicating. Repair any bus wiring issues.
  7. If wiring and sensors check good, perform a module reset (clear codes) and attempt a clean ignition cycle to see if code returns.
  8. Check for available technical service bulletins (TSBs) or PCM software updates; reflash or update PCM software per manufacturer procedures if recommended.
  9. If reflash fails or code persists after wiring, sensors, power/ground, and communication confirmed good, consider bench/repair or replacement of PCM and reprogram to vehicle specifications. Replace only after confirming external causes are eliminated.
  10. After repair or reprogramming, clear codes and perform a road test to confirm problem is resolved and code does not return.

Likely causes

  • PCM software or internal processor fault (most common)
  • Poor battery voltage/weak battery during module operation or update
  • Loose/corroded PCM power/ground or connector issue
  • APP sensor wiring short/open or signal out-of-range causing module fault
  • CAN bus communication fault

Fault status

⚠️ Status
Internal control module detected a performance/processing fault affecting accelerator pedal position input handling; module set stored diagnostic trouble code.
