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.

DTC No.
DTC Detection Condition
Trouble Area
P0705
When one of following conditions is met:
(A) Any 2 or more of the P, N, R, D, 3 and 2 input signals are ON simultaneously (2 trip detection logic)
(B) Any 2 or more of the NSW R, D, 3 and 2 input signals are ON simultaneously (2 trip detection logic)
(C) When both conditions below are met (2 trip detection logic)
  1. One of the NSW, P, N or R input signal is ON
  2. One of the 4 or L input signal is ON
(D) All of the NSW, P, N, R, D, 3 and 2 input signals are OFF (2 trip detection logic)
  1. Open or short in park/neutral position switch circuit
  2. Park/Neutral position switch
  3. 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 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 (R, D, 4, 3, 2 or L).
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

HINT:
Using the intelligent tester 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 non-intrusive 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.
  1. Warm up the engine.
  2. Turn the ignition switch OFF.
  3. Connect the intelligent tester to the DLC3.
  4. Turn the ignition switch ON and turn the tester ON.
  5. Enter the following menus: Powertrain / Engine and ECT / Data List.
  6. Follow the instructions on the tester and read the Data List.
