18560/P2128 - Accelerator Position Sensor 2 (G185): Signal too High

Possible Symptoms

  • MIL on
  • Reduced Power Output

Possible Causes

  • Faulty Accelerator Pedal (very unlikely)
  • Wiring Harness Issue
  • Faulty ECM
  • O2 Sensor(s)

Possible Solutions

  • Inspect and test Wiring harness for Accelerator Pedal, see Repair Manual
  • Visually inspect O2 sensors for damage

Special Notes

  • O2 sensor issues can also cause the following DTCs:
    • 16610/P0226 - Throttle Pedal Position Sensor (G79): Implausible Signal
    • 18565/2133 - Throttle Position Sensor Bank 2: Signal too High
  • In some cases, O2 sensors will damage the ECM. Ross Tech suggest to replace O2 sensors before replacing an ECM for this type of issue.
