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 TCM.

DTC Code
DTC Detection Condition
Trouble Area
P0705
One of the following conditions is met:
(A) Any 2 or more of the following signals are ON simultaneously (2-trip detection logic):
  1. P input signal
  2. N input signal
  3. NSW input signal
  4. R input signal
  5. D input signal
(B) Any of the following signals is ON for 2.0 sec. or more with the shift lever in S (2-trip detection logic):
  1. P input signal
  2. N input signal
  3. NSW input signal
  4. R input signal
(C) P, R, N, D and NSW switches are OFF simultaneously (2-trip detection logic).
  1. Open or short in park/neutral position switch circuit
  2. Transmission control switch (transmission floor shift assembly)
  3. Park/neutral position switch
  4. TCM

MONITOR DESCRIPTION

This DTC indicates a problem with the park/neutral position switch or 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 TCM.
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 in P or N.
The park/neutral position switch sends a signal to the TCM according to the shift lever position (P, R, N, D or S).
The TCM determines that there is a problem with the switch or related parts if it receives more than 1 position signal simultaneously. The TCM will illuminate the MIL and store the DTC.

INSPECTION PROCEDURE


DATA LIST
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 to ON.

  5. Turn the intelligent tester on.

  6. Enter the following menus: Powertrain / ECT / Data List.

  7. According to the display on the intelligent tester, read the Data List.
