P0707
DTC P0707 TRANSAXLE RANGE SWITCH - LOW INPUTCOMPONENT INSPECTION:
GENERAL DESCRIPTION
The Transaxle Range Switch sends the shift lever position information to the TCM (PCM) using a 12 V (battery voltage) signal. When the shift lever is in the D (Drive) position the output signal of Transaxle Range Switch is 12 V 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 PCM/TCM sets this code when the Transaxle Range Switch has no output signal for more than 30 seconds.
DTC DETECTING CONDITION
DTC DETECTING CONDITION:
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 "L" 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 "W/Harness 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 Circuit Inspection" procedure.
POWER CIRCUIT INSPECTION E801CCAI
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 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 PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM 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 scan tool, Clear DTC.
3. Operate the vehicle within DTC Enable conditions in General information.
4. Are DTCs present?
YES - Go to the applicable troubleshooting procedure. Transmission
NO - System performing to specification at this time.
