Pinpoint Test D : TR (Transmission Range) 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 Diagram Set 29 for schematic and connector information Electrical Diagrams.

PINPOINT TEST D : TR (Transmission Range) SENSOR

NOTE: Prior to beginning TR (Transmission Range) sensor pinpoint test, verify TR (Transmission Range) 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.

Is the selector lever cable/linkage correctly adjusted?

Yes
GO to D2.

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

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 (Transmission Control Module) C1750B, harness side and TR (Transmission Range) sensor C167, using the following chart.

TCM Transmission Range Sensor C1750B-24 C167-4 C1750B-25 C167-1 C1750B-34 C167-3 C1750B-35 C167-2

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. Refer to TR (Transmission Range) Sensor Adaptive Learning in Transmission Adaptive Learning Transmission Adaptive Learning.

D3 CHECK THE TRANSAXLE WIRING HARNESS FOR A SHORT TO GROUND

- Measure the resistance between TCM (Transmission Control Module) C1750B, harness side and ground using the following chart.

TCM Ground C1750B-24 Ground C1750B-25 Ground C1750B-34 Ground C1750B-35 Ground

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 (Transmission Control Module)

- 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 (Transmission Range) sensor C167-3, harness side and TR (Transmission Range) sensor C167-2, harness side.





Is the voltage between 4.5 and 5.5 volts?

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

No
INSTALL a new TCM (Transmission Control Module). RECONNECT all components. TEST the system for normal operation. Refer to TR (Transmission Range) Sensor Adaptive Learning in Transmission Adaptive Learning Transmission Adaptive Learning.
