Battery Temperature Sensor: Testing and Inspection
Testing
To perform a complete test of this sensor and its circuitry, refer to the appropriate Powertrain Diagnostic Procedures. To test the sensor only, refer to the
following:
Battery Temperature Sensor Location
1. The sensor is located under the battery and is attached (snapped into) the battery tray. On models equipped with a diesel engine (dual batteries),
only one sensor is used. Location is under battery on drivers side of vehicle. A two-wire pigtail harness is attached directly to the sensor. The
opposite end of this harness connects the sensor to the engine wiring harness.
2. Disconnect the two-wire pigtail harness from the engine harness.
3. Attach ohmmeter leads to the wire terminals of the pigtail harness.
4. At room temperature of 25° C (75-80° F), an ohmmeter reading of 9,000 (9K) to 11,000 (11K) ohms should be observed.
5. If reading is above or below the specification, replace the sensor.
6. Refer to the Replacement for procedures.
