Engine speed may increase unintentionally
- Defect
- It is possible that the internal contact resistance of the crimped joints for the grounding between the throttle position sensor (TPS) and engine control module may increase due to engine vibration. This can lead to an increased TPS voltage output which could lead to an increase in engine revolutions whilst at idle without any throttle input.
- Remedy
- Recall all affected vehicles for the installation of a new wiring harness.
- Vehicles affected
