Defect
The circuit resistance of the Accelorator Position Sensor (APS) and Throttle Position Sensor (TPS) in the wire harness may increase due to a defective ground connection between APS/TPS and ECU. Under this condition, incorrect electrical signals may be transmitted to the Electronic Control Unit (ECU) and resulting in unstable engine idle speed and/or display malfunction codes (50 and/or 60).
