CIRCUIT INSPECTION
DTC P0705 Transmission Range Sensor Circuit Mal-
function (PRNDL Input)
CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.
DTC No.DTC Detection ConditionTrouble Area
P0705
(2±trip detection logic)
All switches are OFF simultaneously for NSW, R, N, D, 3 and
2 positions.
2 or more switches are ON simultaneously for NSW, R, D, 3
and 2 positions.
Open or short in park/neutral position switch circuit
Park/neutral position switch
ECM
MONITOR DESCRIPTION
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 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 shift lever is in the P or N position.
The park/neutral position switch sends a signal to the ECM according to the shift position (NSW, R, D, 3 or
2).
The ECM determines that there is a problem with the switch or related parts if it receives more than 1 position
signal simultaneously. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE
HINT:
According to the DATA LIST displayed by the OBD II scan tool or 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.
(a) Warm up the engine.
(b) Turn the ignition switch off.
(c) Connect the OBD II scan tool or hand±held tester to the DLC3.
(d) Turn the ignition switch to the ON position.
(e) Push the ºONº button of the OBD II scan tool or the hand±held tester.
(f) When you use the hand±held tester:
Select the item ºDIAGNOSIS / ENHANCED OBD II / DATA LISTº.
(g) According to the display on the tester, read the ºDATA LISTº.
