HINT:
DTC P0705 is stored when any of the above detection patterns is met.
MONITOR DESCRIPTION
This DTC indicates a problem with the park/neutral position switch assembly or wire harness of their circuits.
The park/neutral position switch assembly detects the shift lever position and sends a signal to the ECM. For safety, the park/neutral position switch assembly 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 assembly sends a signal to the ECM according to the shift lever position (P, R, N, D or B).
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 then illuminate the MIL and store a DTC.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repairs have been completed, clear the DTCs and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.
-
When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.
Click here
-
Connect the Techstream to the DLC3.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
-
Turn the ignition switch off and wait for 2 minutes or more.
-
Turn the ignition switch to ON and turn the Techstream on.
-
Wait with the shift lever in each position (P, R, N, D or B) for 60 seconds or more each with the ignition switch ON. [*1]
HINT:
[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
-
Enter the following menus: Powertrain / Engine and ECT / Utility / All Readiness.
-
Input the DTC: P0705.
-
Check the DTC judgment result.

HINT:
-
If the judgment result shows NORMAL, the system is normal.
-
If the judgment result shows ABNORMAL, the system has a malfunction.
-
If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
