These Diagnostic Trouble Codes (DTC) indicate a problem with the Park/Neutral Position (PNP) Switch assembly and the wire harness in the Park/Neutral Position Switch assembly circuit.
The Park/Neutral Position Switch assembly detects the shift lever position and sends signals to the Engine Control Module (ECM).
For safety, the Park/Neutral Position Switch assembly detects the shift lever position so that the engine can be started only when the shift lever is in P or N.
The Park/Neutral Position Switch assembly sends a signal to the ECM according to the shift lever position (P, N, NSW, R, D or S). 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.
