DTC P0516: Battery Temperature Sensor Low: Testing

WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ignition on, engine not running. With the DRBIII(R), read the Battery Temp Sensor voltage. If the voltage is below 0.5 volt, go to next step. If the voltage is not below 0.5 volt, see INTERMITTENT CONDITIONS  . Perform POWERTRAIN VERIFICATION TEST VER-5 (NGC)  .
  2. Turn the ignition off. Disconnect the Battery Temp Sensor harness connector. Turn ignition on, engine not running. With the DRBIII(R), read Battery Temp Sensor voltage. If the Battery Temp Sensor voltage reads approximately 5.0 volts, replace the Battery Temperature Sensor. Perform POWERTRAIN VERIFICATION TEST VER-5 (NGC)  . If the Battery Temperature Sensor does not read approximately 5.0 volts, go to next step.
  3. Turn the ignition off. Disconnect the Battery Temp Sensor harness connector. Disconnect the PCM harness connector. Measure the resistance between ground and the Battery Temp Signal circuit in the Battery Temp Sensor harness connector. If the resistance is below 100 ohms, repair the short to ground in the Battery Temp Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER-5 (NGC)  . If the resistance is not below 100 ohms, go to next step.
  4. Turn the ignition off. Disconnect the Battery Temp Sensor harness connector. Disconnect the PCM harness connector. Measure the resistance between the Battery Temp Signal circuit and the Sensor ground circuit in the Battery Temp Sensor harness connector. If the resistance is below 100 ohms, repair the Sensor ground shorted to the Battery Temp Sensor Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER-5 (NGC)  . If the resistance is not below 100 ohms, go to next step.
    5. NOTE: Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
  5. If there are no possible causes remaining, replace and program the Powertrain Control Module. See PROGRAMMING  . Perform POWERTRAIN VERIFICATION TEST VER-5 (NGC)  .
