Pinpoint Test D: TR Sensor

Pinpoint Tests





Any time an electrical connector is disconnected, inspect the connector for terminal condition, corrosion and contamination. Also inspect the connector seal for damage. Clean, repair or install new as necessary.

Pinpoint Tests

Refer to Wiring Diagrams for schematic and connector information. Diagrams By Number

PINPOINT TEST D: TR SENSOR

NOTE: Prior to beginning TR sensor pinpoint test, verify TR sensor adaptive learning. For additional information, refer to Transmission Adaptive Learning Transmission Adaptive Learning.

NOTE: Refer to the transaxle connector illustrations Transaxle Connector Layouts Transaxle Connector Layouts.

-------------------------------------------------
D1 VERIFY SELECTOR LEVER CABLE/LINKAGE ADJUSTMENT

- Verify that the selector lever cable/linkage is correctly adjusted. Refer to Automatic Transaxle/Transmission External Controls Adjustments.
- Is the selector lever cable/linkage correctly adjusted?

Yes
GO to D2.

No
ADJUST the selector lever cable/linkage. REFER to Automatic Transaxle/Transmission External Controls Adjustments.

-------------------------------------------------
D2 CHECK THE TRANSAXLE WIRING HARNESS FOR AN OPEN CIRCUIT

- Ignition OFF.
- Disconnect: Transmission Control Module (TCM) C1750B.
- Inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
- Disconnect: Transmission Range (TR) sensor C167.
- Inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
- Measure the resistance between TCM C1750B, harness side and TR sensor C167, using the following chart.





- Is the resistance less than 5 ohms?

Yes
GO to D3.

No
REPAIR the circuit(s) for an open. RECONNECT all components. TEST the system for normal operation.

-------------------------------------------------
D3 CHECK THE TRANSAXLE WIRING HARNESS FOR A SHORT TO GROUND

- Measure the resistance between TCM C1750B, harness side and ground using the following chart.





- Is the resistance greater than 10,000 ohms?

Yes
Inspect the transaxle wiring harness for signs of physical damage and repair or install a new transaxle wiring harness as necessary. TEST the system for normal operation. If the transaxle wiring harness is not damaged, GO to D4.

No
REPAIR the circuit(s) for a short to ground. RECONNECT all components. TEST the system for normal operation.

-------------------------------------------------
D4 CHECK THE TCM

- Connect: Transmission Control Module (TCM) C1750B.
- Inspect both ends of the connector for damage or pushed-out pins, corrosion, loose wires and missing or damaged seals.
- Ignition ON.
- Measure the voltage between TR sensor C167-3, harness side and TR sensor C167-2, harness side.




- Is the voltage between 4.5 and 5.5 volts?

Yes
INSTALL a new TR sensor. RECONNECT all components. TEST the system for normal operation.

No
INSTALL a new TCM. RECONNECT all components. TEST the system for normal operation.
