P0705

DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)

CIRCUIT DESCRIPTION

DTC Detection Conditions:

The park/neutral position switch detects the shift lever position and sends signals to the ECM. The ECM receives signals (NSW, R, D, 2 and L) from the park/neutral position switch.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

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, D, 2 or L the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE

Step 1:

Step 2:

Step 3:

HINT: In case of using the hand-held tester, start the inspection from step 1 and in case of not using hand-held tester, start from step 2.

CHECK FOR INTERMITTENT PROBLEMS

HINT:

Hand-held tester only:
Inspect the vehicle's ECM using check mode. Intermittent problems are easier to detect with the hand-held tester when the ECM is in check mode. In check mode, the ECM uses 1trip detection logic, which is more sensitive to malfunctions than normal mode (default) that uses 2trip detection logic.

a. Clear DTCs.
b. Switch the ECM from normal mode to check mode using a hand-held tester.
c. Perform a simulation test.
d. Check and wiggle the harness(es), the connector(s) and terminal(s).
