DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)

CIRCUIT DESCRIPTION

DTC Detection Condition:

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

The ECM receives signals (P, R, N, D, 4, 3, 2 and L) from the park/neutral position switch. When the signal is not sent to the ECM from the park/neutral position switch, the ECM judges that the shift lever is in D position. When the shift lever is in the M position (with E-shift main switch for D and M pressed), "M" in the shift position indicator light will come on and when the shift lever is in the D position (with E-shift main switch for D and M released), "D" in the shift position indicator light will come on. When the shift lever is in the L position (with E-shift main switch for 2 and L pressed), "L" in the shift position indicator light will come on and when the shift lever is in the 2 position (with E-shift main switch for 2 and L released), "2" in the shift position indicator light will come on. When the shift lever is in 4 or M position, the ECM prohibits shifting to 5th.

Typical Malfunction Thresholds:

Component Operating Range:

The park/neutral position switch detects the shift lever position and sends a signal to the ECM. For security, the park/neutral position switch detects the shift lever 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 and store the DTC.
