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.

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. Shift 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) connectors 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 terminal condition. 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 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: approx. B+

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".
