DTC P0707 TRANSAXLE RANGE SWITCH - LOW INPUT





COMPONENT 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 0V. 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.





DTC DETECTING CONDITION





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 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 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 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 seminal "8" of the sensor harness connector and chassis ground.
Specification: approximately B+
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 Vehicle Repair" procedure.

SIGNAL CIRCUIT INSPECTION
1. Ignition "OFF".
2. Disconnect "TRANSAXLE RANGE SWITCH" and "TCM (PCM)" connector.
3. Measure resistance between each seminal of the sensor harness connector and TCM (PCM) harness connector as below.
Specification:





< 2.0L >





< 2.7L >





< 2.0L >





< 2.7L >

4. Is resistance within specifications?
YES >>
^ Go to "Component inspection" procedure.
NO >>
^ Check for Open in harness. Repair as necessary and Go to "Verification 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
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 as necessary and then go to "Verification of Vehicle Repair" procedure.
NO >>
^ Replace "TRANSAXLE RANGE SWITCH" as necessary and Go to "Verification Vehicle Repair" procedure.
