PINPOINT TEST C: TR SENSOR
NOTE: Refer to the Transmission Range (TR) Sensor Vehicle Harness Connector illustration within the Transaxle Connector Layouts Transaxle Connector Layouts procedure.
NOTE: Refer to the Transmission Range (TR) Sensor Diagnosis PID Chart within the Transaxle Connector Layouts Transaxle Connector Layouts procedure.
-------------------------------------------------
C1 VERIFY TR SENSOR ALIGNMENT
- Using a scan tool, view the TRD, TRL, TRN, TRP and TRR PIDs to determine if a fault is present in the TR sensor system, refer to the
Transmission Range (TR) Sensor Diagnostic PID Chart in Transaxle Connector Layouts Transaxle Connector Layouts.
- If an electrical issue exists, verify TR sensor alignment.
- Is the TR sensor correctly aligned?
Yes
GO to C2.
No
ADJUST the TR sensor. REFER to Transmission Range (TR) Sensor Adjustment Adjustments. CLEAR the DTCs. TEST the system for normal operation.
-------------------------------------------------
C2 VERIFY SELECTOR LEVER CABLE/LINKAGE ADJUSTMENT
- Verify that the selector lever cable/linkage is correctly adjusted. Refer to Selector Lever Cable Adjustment in Automatic Transmission/Transaxle.
- Is the selector lever cable/linkage correctly adjusted?
Yes
GO to C3.
No
ADJUST the selector lever cable/linkage REFER to Selector Lever Cable Adjustment in Automatic Transmission/Transaxle. TEST the system for normal operation.
-------------------------------------------------
C3 CHECK THE TRANSAXLE POWER SUPPLY CIRCUIT
- Disconnect: TR Sensor C167.
- Ignition ON.
- Measure the voltage between TR sensor C167-1, and ground.
- Is the voltage greater than 10 volts?
Yes
GO to C5.
No
GO to C4.
-------------------------------------------------
C4 CHECK FUSE 26 (10A)
- Ignition OFF.
- Check fuse: Battery Junction Box (BJB) 26 (15A).
- Is the resistance less than 5 ohms?
Yes
REPAIR circuit CBB26 (BU/WH) for an open. CLEAR the DTCs. TEST the system for normal operation.
No
REPAIR circuit CBB26 (BU/WH) for a short to ground. CLEAR the DTCs. TEST the system for normal operation.
-------------------------------------------------
C5 CHECK THE VEHICLE HARNESS FOR A SHORT TO POWER
- Select PARK.
- Ignition OFF.
- Disconnect: PCM C175T.
- Ignition ON.
- Measure the voltage between TR sensor C167 pins 2, 4, 5, 7 and 8 and ground using the following chart:
- Is any voltage present?
Yes
REPAIR the circuit(s) for a short to power. CLEAR the DTCs. TEST the system for normal operation.
No
GO to C6.
-------------------------------------------------
C6 CHECK THE VEHICLE HARNESS FOR A SHORT TO GROUND
- Measure the resistance between TR sensor C167 pins 2, 4, 5, 7 and 8 and ground using the following chart:
- Is the resistance greater than 10,000 ohms?
Yes
GO to C7.
No
REPAIR the circuit(s) for a short to ground. CLEAR the DTCs. TEST the system for normal operation.
-------------------------------------------------
C7 CHECK TR SENSOR CIRCUITRY FOR AN OPEN CIRCUIT
- Measure the resistance between TR sensor C167 pins 2, 4, 5, 7 and 8 and the corresponding PCM C175T pin using the following chart:
- Is the resistance less than 5 ohms?
Yes
GO to C8.
No
REPAIR the circuit(s) for an open. CLEAR the DTCs. TEST the system for normal operation.
-------------------------------------------------
C8 CHECK THE TR SENSOR RESISTANCE
- Measure the resistance between TR sensor C167 pins, component side, using the following chart:
- Are the resistances less than 5 ohms?
Yes
INSTALL a new PCM. REFER to Computers and Control Systems.
No
INSTALL a new TR sensor. REFER to Transmission Range (TR) Sensor Service and Repair. CLEAR the DTCs. TEST the system for normal operation.
