PINPOINT TEST C: TR SENSOR

NOTE: Refer to the Transmission Range (TR) Sensor Connector illustration Transaxle Connector Layouts Transaxle Connector Layouts.

NOTE: Refer to the Transmission Range (TR) Sensor Diagnosis Chart Transaxle Connector Layouts Transaxle Connector Layouts.

-------------------------------------------------
C1 VERIFY TR SENSOR ALIGNMENT


- Verify the Transmission Range (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 FNR5. TEST the system for normal operation.

-------------------------------------------------
C2 VERIFY THE SELECTOR LEVER CABLE/LINKAGE ADJUSTMENT


- Verify that the selector lever cable/linkage is correctly adjusted.
- Is the selector lever cable/linkage correctly adjusted?

Yes
GO to C3.

No
ADJUST the selector lever cable/linkage. TEST the system for normal operation.

-------------------------------------------------
C3 CHECK THE TR SENSOR CIRCUITRY FOR A SHORT TO GROUND


- Ignition OFF.
- Disconnect: Transaxle Main Valve Body Vehicle Harness C1534.
- Disconnect: TR Sensor C1537.
- Disconnect: Transmission Control Module (TCM) C2352B.
- Disconnect: Intermediate Shaft Speed Sensor C1088.
- Measure the resistance between TR sensor C1537-2, circuit VET28 (GY/VT) and ground.




- Measure the resistance between C1537-3, circuit CET37 (BN/WH) and ground.




- Is the resistance greater than 10,000 ohms?

Yes
GO to C4.

No
REPAIR the circuit in question for an open. TEST the system for normal operation.

-------------------------------------------------
C4 CHECK THE TR SENSOR CIRCUITRY FOR A SHORT TO POWER


- Ignition ON.
- Measure the voltage between TR sensor C1537-2, circuit VET28 (GY/VT) and ground.




- Measure the voltage between TR sensor C1537-3, circuit CET37 (BN/WH) and ground.




- Is any voltage present?

Yes
REPAIR the circuit in question for a short to power. TEST the system for normal operation.

No
GO to C5.

-------------------------------------------------
C5 CHECK THE TR SENSOR CIRCUITRY FOR AN OPEN


- Ignition OFF.
- Measure the resistance between TR sensor C1537-2, circuit VET28 (GY/VT) and TCM C2352B-5, circuit VET28 (GY/VT).




- Measure the resistance between TR sensor C1537-3, circuit CET37 (BN/WH) and TCM C2352B-21, circuit CET37 (BN/WH).




- Are the resistances less than 5 ohms?

Yes
GO to C6.

No
REPAIR the circuit in question. TEST the system for normal operation.

-------------------------------------------------
C6 CHECK THE TR SENSOR RESISTANCE


- Measure the resistance between TR sensor pins 2 and 3 component side, while shifting the transmission manual control lever as follows:
- PARK position, 3,370-5,230 ohms
- REVERSE position, 1,250-1,750 ohms
- NEUTRAL position, 630-870 ohms
- DRIVE position, 330-450 ohms
- LOW position, 150-250 ohms




- Are the resistances within the expected values?

Yes
INSTALL a new TCM. TEST the system for normal operation.

No
INSTALL a new TR sensor. REFER to Transmission Range (TR) Sensor Service and Repair. TEST the system for normal operation.
