Condition

Some customers may comment that the MIL is illuminated when shifting the transmission from Park.

Some technicians may find DTC P0333 (Knock Sensor Circuit High Voltage Bank 2) set in the Engine Control Module (ECM).

Cause

DTC P0333 can set due to voltage from the transmission park/neutral signal 1 circuit bleeding into the knock sensor system circuits.

Correction

To correct this condition, follow service information for diagnostic code P0333. If service information does not isolate the concern, then inspect the K20 ECM X2 electrical connector for debris, connector and/or terminal concerns.
