Toyota RAV4. 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.

Toyota RAV4. Transmission range sensor circuit malfunction (prndl input)


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, 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's data list allows switch, sensor, actuator and other item values to be read without removing any parts. Reading the data list early in troubleshooting is one way to save 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 can vim. Then connect the can vim to the dlc3.
  4. Turn the ignition switch on and turn the tester on.
  5. Enter the following menus: diagnosis / enhanced obd ii / data list.
  6. Follow the instructions on the tester and read the data list.
