DTC P0705 TRANSMISSION RANGE SENSOR CIRCUIT
MALFUNCTION (PRNDL INPUT)

CIRCUIT DESCRIPTION

DTC Detection Condition:

The Park/Neutral Position (PNP) 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 PNP switch.

When the shift lever is on 4 (with transmission control switch for D and 4 pressed., "4" in the shift position indicator lamp will illuminate and when the shift lever is on D (with transmission control switch for D and 4 released., "D" in the shift position indicator lamp will illuminate.

When the shift lever is on L (with transmission control switch for 2 and L pressed., "L" in the shift position indicator lamp will illuminate and when the shift lever is on 2 (with transmission control switch for 2 and L released., "2" in the shift position indicator lamp will illuminate.

Typical Enabling Conditions:

Typical Malfunction Thresholds Part 1:

Typical Malfunction Thresholds Part 2:

Component Operating Range:

The PNP switch detects the shift lever position and sends a signal to the ECM.

For security, the PNP 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 PNP 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 illuminate the MIL and store the DTC.
