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:
1. The sensor is located inboard of the battery and is attached to 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 body wiring harness.
2. Disconnect the two-wire pigtail harness from the body 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 to 11,000 Ohms should be observed.
5. If reading is above or below the specification, replace the sensor.
6. Refer to the Replacement for procedures.
