P0705

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.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

Component Operating Range:

These DTCs indicate a problem with the park/neutral position switch and the wire harness in the park/neutral position switch circuit.
The park/neutral position switch detects the shift lever position and sends signals 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.

INSPECTION PROCEDURE

HINT: According to the DATA LIST displayed by the hand-held tester, you can read the value of the switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as the first step of troubleshooting is one method to shorten labor time.

NOTE: In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

a. Turn the ignition switch off.
b. Connect the hand-held tester to the CAN VIM. Then connect the CAN VIM to the DLC3.
c. Turn the ignition switch to the ON position.
d. Push the "ON" button of the OBD II scan tool or the hand-held tester.
e. Select the item "DIAGNOSIS/ENHANCED OBD II/DATA LIST".
f. According to the display on tester, read the "DATA LIST".
