DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)

DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.





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 in receives more than 1 position signal simultaneously. The ECM will turn on the MIL and store the DTC.
