CIRCUIT INSPECTION

DTC

P0705

Transmission Range Sensor Circuit Mal-
function (PRNDL Input)

CIRCUIT DESCRIPTION

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

DTC No.

DTC Detection Condition

Trouble Area

P0705

(2–trip detection logic)

All switches are OFF simultaneously for NSW, R, N, D, 3 and

2 positions.

2 or more switches are ON simultaneously for NSW, R, D, 3

and 2 positions.

Open or short in park/neutral position switch circuit

Park/neutral position switch

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 (NSW, R, D, 3 or
2).
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.
