DTC P0517: Battery Temperature Sensor High: Testing
- Turn ignition on, engine not running. With the DRBIII®, read the Battery Temp sensor voltage. If the voltage is above 4.9 volts, go to next step. If the voltage is not above 4.9 volts, see INTERMITTENT CONDITIONS . Perform POWERTRAIN VERIFICATION TEST VER-5 .
- Turn the ignition off. Disconnect the Battery Temp sensor harness connector. Turn the ignition on, engine not running. Measure the voltage of the (K118) Battery Temp Signal circuit in the Battery Temp sensor harness connector. If voltage is above 5.2 volts, repair the short to battery voltage in the (K118) Battery Temp Signal circuit. See POWERTRAIN VERIFICATION TEST VER-5 . If the voltage is not above 5.2 volts, go to next step.
- Turn the ignition off. Disconnect the Battery Temp harness connector. Connect a jumper wire between the Battery Temp Signal circuit and the sensor ground circuit in the Battery Temp harness connector. Turn the ignition on, engine not running. With the DRBIII, read the Battery Temp sensor voltage. If the voltage is below 1 volt, replace the battery temp sensor. See POWERTRAIN VERIFICATION TEST VER-5 If the voltage is not below 1 volt, go to next step.
- Turn the ignition off. Disconnect the Battery Temp sensor harness connector. Disconnect the PCM harness connector. Measure the resistance of the (K118) Battery Temp Signal circuit from the Battery Temp Sensor harness connector to the appropriate terminal of Miller Special Tool (8815). If the resistance is below 5 ohms, go to next step. If the resistance is not below 5 ohms, repair the open in the (K118) Battery Temp Signal circuit. See POWERTRAIN VERIFICATION TEST VER-5 .
- Turn the ignition off. Disconnect the Battery sensor harness connector. Disconnect the PCM harness connector. Measure the resistance of the (K167) sensor ground circuit from the battery temp sensor harness connector to the appropriate terminal of Miller Special Tool (8815). If the resistance is below 5 ohms, go to next step. If the resistance is not below 5 ohms, repair the open in the (K167) sensor ground circuit. See POWERTRAIN VERIFICATION TEST VER-5 .
- If there are no possible causes remaining, replace and program the PCM. See PROGRAMMING . Perform POWERTRAIN VERIFICATION TEST VER-5 .
CAUTION:
DO NOT probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal to pin connection. Install Miller Special Tool (8815) to perform diagnosis.

NOTE:
Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.
