Subaru Crosstrek Service Manual: Dtc p0708 transmission range sensor "a" circuit high

CONTINUOUSLY VARIABLE TRANSMISSION (DIAGNOSTICS) > Diagnostic Procedure with Diagnostic Trouble Code (DTC)

DTC P0708 TRANSMISSION RANGE SENSOR "A" CIRCUIT HIGH

DTC detecting condition:

Immediately at fault recognition

Trouble symptom:

Shift characteristics are erroneous.

The range position of the select lever and the position of shift indicator display do not match.

CAUTION:

Use the check board when measuring the TCM terminal voltage and resistance.

1.CHECK INPUT SIGNAL FOR TCM.

1) Turn the ignition switch to ON.

2) Move the select lever to each range, and read the data of «P Range», «R Range Signal», «N Range» and «D Range Signal» using the Subaru Select Monitor.

Is the display of the corresponding range “ON”?

7.CHECK FOR POOR CONTACT.

Is there poor contact between TCM, inhibitor switch, transmission ground?

Repair the poor contact.

Replace the TCM. Transmission Control Module (TCM)">

1. OUTLINE OF DIAGNOSIS

Detect the malfunction of Range Switch.

Judge as NG if there is no input from all Range Switches.

2. EXECUTION CONDITION

Secondary Parameters

Execution condition

12 V battery system voltage

≥ 10 V

Vehicle speed (calculated from secondary pulley shaft speed)

≥ 6 MPH

3. DIAGNOSTIC METHOD

If the duration of time while the following conditions are met is longer than the time indicated, judge as NG.

Judgment Value

Malfunction Criteria

Threshold Value

All transmission range switches OFF

NOTE:

“Transmission range switch OFF” is defined as transmission range switch input voltage ≥ 3.4 V.

True

Time Needed for Diagnosis: 3 seconds
