Transmission Range Sensor Circuit Malfunction (PRNDL Input)

HINT:

After confirming DTC P0705, use the intelligent tester to confirm the PNP switch signal in the ALL menu (to reach the ALL menu: DIAGNOSIS / ENHANCED OBD II / DATA LIST / ALL).

WIRING DIAGRAM

Refer to DTC P0705 for 2WD model (See page AX-40) or 4WD model (See page AX-40).

INSPECTION PROCEDURE

Refer to DTC P0705 for 2WD model (See page AX-41) or 4WD model (See page AX-41).

HINT:

Read freeze frame data using the intelligent tester or OBD II scan tool. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was running or stopped, if the engine was warmed up or not, if the air-fuel ratio was LEAN or RICH, and other data from the time the malfunction occurred.
