P060D: Internal Control Module Accelerator Pedal Position Performance

What it means

The control module detected a performance problem related to accelerator pedal position. The code alone does not establish whether the cause is internal processing or an external signal issue.

At a glance

• Usually lights the check-engine light

How it works

The ECM processes accelerator pedal position sensor signals to determine the driver's requested throttle. P060D sets when the module detects a performance problem in its processing or interpretation of that pedal-position information; it does not by itself distinguish an internal fault from a pedal signal or circuit problem.

Common causes

Most likely first.

1. Accelerator-pedal position sensor signal or circuit fault
2. Open, shorted, or high-resistance pedal wiring
3. Poor connector contact or sensor reference voltage
4. Control-module hardware or software fault

Symptoms

• Check engine light on
• Possible limp mode or no-start
• Multiple follow-up faults across modules
• Reset/relearn may be needed after repair

How to diagnose it

1. Save freeze-frame data and scan all modules for pedal-position, reference-voltage, and communication faults before clearing codes.
2. With the ignition off, inspect the accelerator pedal connector and harness for loose pins, corrosion, moisture, or wiring damage, especially where the loom moves near the pedal.
3. Use a scan tool to compare accelerator pedal position sensor channels while slowly pressing and releasing the pedal; look for dropouts, jumps, or disagreement with manufacturer data.
4. Check the pedal sensor reference, ground, and signal circuits for opens, shorts, or excessive resistance using the manufacturer's wiring diagram and specifications.
5. If pedal signals and wiring are sound, check for applicable ECM software updates and verify module power and grounds before condemning the ECM.

Common fixes

• Reconnect or clean a poor accelerator pedal sensor connector contact.
• Repair open, shorted, or high-resistance wiring in the pedal sensor circuit.
• Replace the accelerator pedal assembly if its position signals fail the manufacturer's tests.
• Update or reprogram the ECM if a relevant calibration correction is specified.
• Replace and program the ECM only if external signals, power, grounds, and software have been ruled out.

Can I keep driving?

If pedal response is delayed, inconsistent, or reduced, avoid driving in traffic or at speed because acceleration may be unpredictable. Arrange prompt diagnosis; stop driving if you cannot reliably control engine power.
