MIL Comes On With DTC P0132
SYMPTOM
The MIL is on, and DTC P0132 [primary heated oxygen sensor circuit high voltage (sensor 1)] is set.
PROBABLE CAUSE
Moisture intrusion causes corrosion of the engine wire harness and the primary heated oxygen sensor (H02S). This corrosion affects the sensor's output voltage to the ECM/PCM.
CORRECTIVE ACTION
Replace the engine wire harness and the primary H025. Secure the sensor connector pigtail to the wire harness to prevent moisture intrusion.
