Toyota Sienna Service Manual: Transmission Range Sensor Circuit Malfunction (PRNDL Input)
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.
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 or 4WD model.
INSPECTION PROCEDURE
Refer to DTC P0705 for 2WD model or 4WD model.
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.
