Battery Temperature Sensor (BTS) No Code Test: Testing
WARNING: This page is about a different car, the 2002 Jeep Liberty. However, it is still accessible from the selected car via links, so may be relevant.
- Turn ignition on, engine not running. With the DRBIII(R) in sensors, read the "Ambient/Batt Tmp Deg" value and record the reading. Using a temperature probe, measure the air temperature near the AMBIENT/BATT temperature sensor. Is the recorded AMBIENT/BATT temperature value within 10°F (-12.2°C) of the temperature probe reading? If yes, go to next step. If no, replace the AMBIENT/BATT temperature sensor. Perform POWERTRAIN VERIFICATION TEST VER-3 .
- Turn the ignition off. Disconnect the AMBIENT/BATT harness connector. Check connectors, clean and repair as necessary. Connect a jumper across the terminals of the AMBIENT/BATT harness side. Turn ignition on, engine not running. With the DRBIII(R) in Inputs/Outputs, read the AMBIENT/BATT voltage. Is the voltage reading equal to zero? If yes, replace the AMBIENT/BATT temperature sensor. Perform POWERTRAIN VERIFICATION TEST VER-3 . If no, test complete.
