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

INSPECTION PROCEDURE
Refer to DTC P0705 for 2WD model or 4WD model.

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.
