P0707
DTC P0707 TRANSAXLE RANGE SWITCH - LOW INPUTCOMPONENT LOCATION:
GENERAL DESCRIPTION
The Transaxle Range Switch sends the shift lever position information to the TCM (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 0 V The TCM (PCM) judges the shift lever position by reading all signals, for the Transaxle Range Switch, simultaneously.
DTC DESCRIPTION
The TCM (PCM) sets this code when the Transaxle Range Switch has no output signal for more than 30 seconds.

SCHEMATIC DIAGRAM:
MONITOR SCAN TOOL DATA
1. Connect SCAN TOOL to data link connector (DLC).
2. Ignition ON & Engine OFF.
3. Monitor the TRANSAXLE RANGE SWITCH parameter on the SCAN TOOL.
4. Move selector lever from P range to other range.
5. Does TRANSAXLE RANGE SWITCH follow the reference data?
YES > Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was repaired and TCM (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. CHECK POWER TO RANGE SWITCH
1. Disconnect TRANSAXLE RANGE SWITCH connector.
2. Ignition ON & Engine OFF.
3. Measure voltage between terminal 8 of the sensor harness connector and chassis ground.
Specification: approximately B+
Specification:
4. Is voltage within specifications?
YES > Go to Signal circuit inspection procedure.
NO > Check that Fuse 24-10A is installed or not blown. Check for open 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 TCM (PCM) connector.
3. Measure resistance between each terminal of the sensor harness connector and TCM (PCM) harness connector.
Specification
Specification:
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 the resistance between each terminal of the sensor.
Specification: approximately 0 Ohms
Specification:
4. Is resistance within specifications?
YES > Substitute with a known-good TCM (PCM) and check for proper operation. If the problem is corrected, replace PCM/TCM 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 too[ and select Diagnostic Trouble Codes (DTCs) mode.
2. Using a SCAN TOOL, 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.
