P0705 | Transmission Range Sensor Circuit Malfunction (PRNDL Input) |
DESCRIPTION
The park/neutral position switch and shift lock control unit assembly (transmission control switch) detect the shift lever position and send signals to the ECM.

MONITOR DESCRIPTION
For security, the park/neutral position switch detects the gearshift position so that engine can be started only when the vehicle is in the P or N shift position.
When the park/neutral position switch and shift lock control unit assembly (transmission control switch) send more than one signal at a time from switch positions P, R, N, D, S (SDSW) or B, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE
Note
Inspect the fuses for circuits related to this system before performing the following inspection procedure.
PROCEDURE
READ VALUE USING INTELLIGENT TESTER (NEUTRAL POSITION SW SIGNAL AND SHIFT SW STATUS)
Connect the intelligent tester to the DLC3.
Turn the ignition switch to ON.
Turn the tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List.
In accordance with the display on the tester, read the Data List.
Tester Display | Measurement Item/Range | Normal Condition | Diagnostic Note |
---|---|---|---|
Neutral Position SW Signal | PNP switch status/ ON or OFF |
Shift lever position; P or N: ON Except P and N: OFF |
When shift lever position displayed on intelligent tester differs from actual position, adjustment of PNP switch or shift cable may be incorrect. |
Shift SW Status (R Range) | PNP switch status/ ON or OFF |
Shift lever position; R: ON Except R: OFF |
|
Shift SW Status (P Range) | PNP switch status/ ON or OFF |
Shift lever position; P: ON Except P: OFF |
|
Shift SW Status (N Range) | PNP switch status/ ON or OFF |
Shift lever position; N: ON Except N: OFF |
|
Shift SW Status (D Range) | PNP switch status/ ON or OFF |
Shift lever position; D or S: ON Except D and S: OFF |
|
Shift SW Status (B Range) | PNP switch status/ ON or OFF |
Shift lever position; B: ON Except B: OFF |

PERFORM INITIALIZATION
Note
Performing reset memory/initialization will clear the learned values of both the yaw rate and acceleration sensor (deceleration sensor 0 point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate and acceleration sensor 0 point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:

After reset memory, always perform yaw rate and acceleration sensor (deceleration sensor 0 point) calibration first, and then the CVT oil pressure calibration.
Always perform the 0 point calibration with the vehicle on level ground.
Do not shake or vibrate the vehicle during the 0 point calibration.
Using the intelligent tester, perform the reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration Click here.
