P0705

DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input)

DESCRIPTION
The Park/Neutral Position (PNP) switch detects the shift lever position and sends signals to the ECM.





MONITOR DESCRIPTION
This DTC indicates 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 the engine can be started only when the shift lever is on P or N.

The park/neutral position switch sends a signal to the ECM according to the shift lever position (P, R, N, D or S).

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 illuminate the MIL and store the DTC.

INSPECTION PROCEDURE
1. DATA LIST

HINT: Using the intelligent tester or Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This nonintrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

NOTICE: 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) Warm up the engine.
(b) Turn the ignition switch OFF.
(c) Connect the intelligent tester or Techstream to the DLC3.
(d) Turn the ignition switch ON and push the tester switch ON.
(e) Enter the following menus:
(1) Intelligent tester - Select: DIAGNOSIS / OBD/MOBD / ECT / DATA LIST.
(2) Techstream - Select: Powertrain / Engine and ECT / Data List.
(f) Follow the instructions on the tester and read the Data List.
