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
The park/neutral position switch detects the gearshift position and sends a signal to the ECM. For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in P or N shift position. When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N or D, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
