P0708

DTC P0708





GENERAL DESCRIPTION
The Transaxle range switch sends the shift lever position information to the PCM using a 12V (battery voltage) signal. When the shift lever is in the D (Drive) position the output signal of transaxle range switch is 12V and in all other positions the voltage is 0V. The PCM judges the shift lever position by reading all signals, for the transaxle range switch, simultaneously.

DTC DESCRIPTION
The PCM sets this code when the transaxle range switch outputs multiple signals for an extended period of time.

SCHEMATIC DIAGRAM





MONITOR SCANTOOL DATA
1. Connect Scantool to data link connector (DLC).
2. Ignition "ON" & Engine "OFF".
3. Monitor the "TRANSAXLE RANGE SWITCH" parameter on the Scantool.
4. Move selector lever from "P" range to "L" range.





5. Does "TRANSAXLE RANGE SWITCH" follow the reference data?
YES
^ Fault is intermittent caused by poor contact in the sensors and/or PCM's connector or was repaired and PCM memory was not cleared. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and go to "Verification of vehicle repair" procedure.
NO
^ Go to "Terminal & connector inspection" procedure.

TERMINAL & CONNECTOR INSPECTION
1. Many malfunctions in the electrical system are caused by poor harness and terminals. Faults can also be caused by interference from other electrical systems, and mechanical or chemical damage.
2. Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration, or damage.
3. Has a problem been found?
YES
^ Repair as necessary and go to "Verification of vehicle repair" procedure.
NO
^ Go to "Power supply circuit inspection" procedure.

POWER SUPPLY CIRCUIT INSPECTION
1. Disconnect "TRANSAXLE RANGE SWITCH" connector.
2. Ignition "ON" & Engine "OFF".
3. Measure voltage between each terminal of the sensor harness connector and chassis ground.
Specification: Shown below





4. Is voltage within specifications?
YES
^ Go to "Signal circuit inspection" procedure.
NO
^ Check for short in harness. Repair as necessary and go to "Verification of vehicle repair" procedure.

SIGNAL CIRCUIT INSPECTION
1. Ignition "OFF".
2. Disconnect "TRANSAXLE RANGE SWITCH" and "PCM" connector.
3. Measure resistance between each terminals of the sensor harness to check for Short.
Specification: Infinite





4. Is resistance within specifications?
YES
^ Go to "Component inspection" procedure.
NO
^ Check for open in harness. Repair as necessary and go to "Verification of vehicle repair" procedure.

COMPONENT INSPECTION
1. Ignition "OFF".
2. Remove "TRANSAXLE RANGE SWITCH".
3. Measure continuity (resistance) between each terminals of the sensor.
Specification: approximately 0 Ohms





4. Is resistance within specifications?
YES
^ Substitute with a known-good PCM and check for proper operation. If the problem is corrected, replace PCM as necessary and then go to "Verification of vehicle repair" procedure.
NO
^ Replace "TRANSAXLE RANGE SWITCH" as necessary and go to "Verification of vehicle repair" procedure.

VERIFICATION OF VEHICLE REPAIR
After a repair, it is essential to verify that the fault has been corrected.
1. Connect scan tool and select "Diagnostic Trouble Codes (DTCs)" mode.
2. Using a Scantool, clear DTC.
3. Operate the vehicle within DTC enable conditions in general information.
4. Are any DTCs present?
YES
^ Go to the applicable troubleshooting procedure.
NO
^ System performing to specification at this time.
