==== 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:
**[[18565/P2133]] - Throttle Position Sensor Bank 2: Signal too High
**[[18560/P2128]] - Accelerator Position Sensor 2 (G185): 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.
