Voltage on position switch 1 and position switch 2 is less than 0.127 V for 100 ms continuously after 2 consecutive times.

P0708

Voltage on position switch 1 and position switch 2 is more than 4.87 V for 100 ms continuously after 2 consecutive times.

Action Taken When the DTC Sets

* DTCs P0706, P0707, and P0708 are Type A DTCs.

* The TCM freezes transmission adaptive functions.

* If output speed sensor is 0 RPM, Range is D, 2nd gear is hold and service mode will be set.

* The engine start is locked after engine has stopped.

Conditions for Clearing the DTC

* DTCs P0706, P0707, and P0708 are Type A DTCs.

* Voltage of two selector position sensor are within 0.127-4.87 V and sum of two position sensor voltage has deviation within 0.29 V from

standard value 5 V.

Circuit/System Verification

1. If there are any other transmission DTCs set, diagnose those DTCs first. Refer to Diagnostic Trouble Code (DTC) List - Vehicle (See:

Diagnostic Trouble Code Descriptions/Diagnostic Trouble Code (DTC) List - Vehicle).

Note: It is especially important to closely observe the Park and Neutral to Drive transitional positions while moving the shift lever and

observing for possible misalignment or slack in the shifter mechanism.

2. Ignition ON, observe the scan tool Transmission Range Switch parameter while slowly moving the gear shift lever from Park and through all

ranges. Verify the gear shift lever position matches the scan tool parameter.

瀚慖f not within the specified value, refer to Range Selector Lever Cable Adjustment (See: Transmission and Drivetrain/Automatic

Transmission/Transaxle/Shift Linkage/Shift Cable/Adjustments) and Transmission Adaptive Functions (See: Transmission and

Drivetrain/Automatic Transmission/Transaxle/Description and Operation/AF40-6 - Automatic Transmission/Transmission Adaptive

Functions).

3. Ignition ON, observe the scan tool Transmission Range Switch parameter while slowly moving the gear shift lever from Park and through all

ranges. Verify the gear shift lever position matches the scan tool parameter.
