MONITOR DESCRIPTION
These DTCs indicate a problem with the park / neutral position switch and the wire harness in the park /
neutral position switch circuit.
The park / neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park / neutral position switch detects the shift lever position so that engine can be started
only when the shift lever is in the P or N position.
The park / neutral position switch sends a signal to the ECM according to the shift position (P, R, N or D).
The ECM determines that there is a problem with the switch or related parts if it receives more than 1
position signal simultaneously. The ECM will turn on the MIL and store the DTC.
