Driver did not depress the accelerator during the required diagnostic/test procedure
Faulty accelerator pedal position (APP) sensor or throttle position sensor (TPS)
Open, short or intermittent wiring/connectors between APP/TPS and the PCM/ECM
Low or unstable battery/charging system voltage during test
Faulty PCM/ECM or corrupted software/calibration
Other stored engine/transmission faults preventing test completion

Malfunction Indicator Lamp (MIL) or warning lamp may be set (depends on manufacturer)
Code present in memory but vehicle may run normally if no other faults
Inability to complete certain drive tests or readiness checks
Possible limp-home mode if related throttle control faults are also present

Read freeze-frame and full DTC list; note conditions when code set
Confirm test procedure and repeat ensuring all required conditions are met (park/neutral, parking brake, engine off/on as required)
Inspect APP and TPS connectors for corrosion, damage or looseness
Use scan tool to monitor APP1/APP2 and TPS live data while operating pedal
Check battery voltage and charging system during test
Wiggle-test wiring for intermittent faults; backprobe connectors if safe

Accelerator pedal position (APP) sensor voltages/percent for both channels (APP1/APP2) — should correlate and change smoothly with pedal travel
Throttle position sensor (TPS) or throttle plate angle — moves in response to pedal input
5 V reference and signal ground integrity
Battery voltage during test (should be stable around nominal)
Relevant CAN bus messages/PCM inputs if applicable

Confirm safety: vehicle secured, parking brake on, transmission in required gear (park/neutral).
Use a capable scan tool to clear the code and re-run the specific readiness/self-test while monitoring APP and TPS live data.
If code returns, observe APP1 and APP2 values at rest and while depressing pedal; they should move smoothly and be within expected ranges and correlate with each other.
Inspect pedal and throttle body connectors for corrosion, bent pins, water intrusion and secure connections; repair as needed.
Perform continuity and resistance checks on wiring between APP/TPS and PCM if signal behavior is abnormal or intermittent.
Check vehicle battery and charging system; repeat test with proper voltage if low.
If wiring and sensors test good but code persists, check for related DTCs (e.g., sensor correlation, throttle actuator faults) and consider PCM software update or replacement per manufacturer service information.
After repairs, erase codes and verify the diagnostic/test completes successfully and no related codes return.

Test conditions not met (vehicle not in park/neutral, brakes not applied, parking brake not set)
Bad or misaligned accelerator pedal sensor producing out-of-range or no signal
Loose or corroded connector at pedal/throttle body
Intermittent CAN or signal wiring fault that prevents correct pedal position reporting
