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 on the front of the battery tray. 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.
