DESCRIPTION
The Park/Neutral Position (PNP) switch detects the shift lever position and sends signals to the ECM.
DTC Code | DTC Detection Condition | Trouble Area |
---|---|---|
P0705 | When one of the following conditions is met: (A) Any 2 or more of the following signals are ON simultaneously (2 trip detection logic).
(B) Any 2 or more of the following signals are ON simultaneously (2 trip detection logic).
(C) Any of the following signals are ON for 2.0 sec. or more when the shift lever is in S (2 trip detection logic).
(D) All the signals are OFF simultaneously for the P, R, N and D positions (2 trip detection logic). |

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 in 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
DATA LIST
Tech Tips
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.
Note
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.
Warm up the engine.
Turn the engine switch off.
Connect the intelligent tester to the DLC3.
Turn the engine switch on (IG).
Turn the intelligent tester on.
Enter the following menus: Powertrain / Engine and ECT / Data List.
According to the display on the intelligent tester, read the Data List.
