| DTC Code | DTC Name |
|---|---|
| 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 safety, 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, M the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.

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/ OFF or ON |
|
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 (P Range) | PNP switch status/ OFF or ON |
|
|
| Shift SW Status (R Range) | PNP switch status/ OFF or ON |
|
|
| Shift SW Status (N Range) | PNP switch status/ OFF or ON |
|
|
| Shift SW Status (D Range) | PNP switch status/ OFF or ON |
