DTC P0705 Transmission Range Sensor Circuit Malfunction (PRNDL Input) |
DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.DTC No. | DTC Detection Condition | Trouble Area |
P0705 | (A) Any 2 or more signals of the following are ON simultaneously (2-trip detection logic)
|
|
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 engine can be started only when the shift lever is in the P or N position.
The park/neutral position switch sends a signal to the ECM according to the shift position (P, R, N, or D). 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 turn on the MIL and store the DTC.

INSPECTION PROCEDURE
- NOTICE:
- Perform the universal trip to clear permanent DTCs (COROLLA_ZRE142 RM000000W770S6X.html).
- HINT:
- Using 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 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.
READ DATA LIST |
Warm up the engine.
Turn the ignition switch off.
Connect Techstream to the DLC3.
Turn the ignition switch to the on position.
Turn on the tester.
Select the item "Powertrain / Engine and ECT / Data List".
According to 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/ ON or OFF | Shift lever position is: P and N: ON Except P and N: OFF | When the shift lever position displayed on Techstream differs from the actual position, adjustment of the PNP switch or the shift cable may be incorrect. |
Shift SW Status (R Range) | PNP Switch Status/ ON or OFF | Shift lever position is: R: ON Except R: OFF | ↑ |
Shift SW Status (P Range) | PNP Switch Status/ ON or OFF | Shift lever position is: P: ON Except P: OFF | ↑ |
Shift SW Status (N Range) | PNP Switch Status/ ON or OFF | Shift lever position is: N: ON Except N: OFF | ↑ |
Shift SW Status (D Range) | PNP Switch Status/ ON or OFF | Shift lever position is: D and S: ON Except D and S: OFF | ↑ |
Sports Mode Selection SW | Sport Mode Select Switch Status/ ON or OFF | Shift lever position is: S, "+" and "-": ON Except S, "+" and "-": OFF | - |
