DTC P0516: Battery Temperature Sensor Low: Testing

  1. Ignition on, engine not running. With the DRBIII® scan tool, read the battery temp sensor voltage. Is the voltage below 0.1 volt? If yes, go to next step. If no, see INTERMITTENT CONDITION  under SELF-DIAGNOSTIC SYSTEM.
  2. Turn the ignition off. Disconnect the battery temp sensor harness connector. Ignition on, engine not running. With the DRBIII® scan tool, read battery temp sensor voltage. Does the battery temp sensor voltage read approximately 5.0 volts? If yes, replace the battery temperature sensor. If no, go to next step.
  3. Turn the ignition off. Disconnect the battery temp sensor harness connector. Disconnect the PCM harness connectors. Measure the resistance between ground and the (K118) battery temp signal circuit in the battery temp sensor harness connector. Is the resistance below 100 ohms? If yes, repair the short to ground in the (K118) battery temp signal circuit. If no, go to next step.
  4. Turn the ignition off. Disconnect the battery temp sensor harness connector. Disconnect the PCM harness connectors. Measure the resistance between the (K118) battery temp signal circuit and the (K167) sensor ground circuit in the battery temp sensor harness connector. Is the resistance below 100 ohms? If yes, repair the (K167) sensor ground shorted to the (K118) battery temp sensor signal circuit. If no, go to next step.
  5. Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary. If there are no possible causes remaining, replace and program the PCM. See PROGRAMMING .
