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:
*1: Gate shift lever type
*2: Shift lever with Multi-mode automatic transmission type

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, D, 3[*1] or 2[*1], the ECM interprets this as a fault in the switch. The ECM will turn on the MIL.

HINT:
