P0516-BATTERY TEMPERATURE SENSOR LOW DIAGNOSTIC TEST REFERENCE
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Ignition on, engine not running. With the DRBIII® record all DTCs and the related Freeze Frame data. With DRBIII®, monitor the Battery Temperature Sensor voltage. Is the voltage below 0.0392 of a volt? Yes --> Go To 2 No --> Refer to the INTERMITTENT CONDITION SYMPTOM . Perform POWERTRAIN VERIFICATION TEST VER - 2 . |
All |
| 2 | With the DRBIII® in sensors, read the Battery Temp Sensor Voltage value. Disconnect the Battery Temperature Sensor harness connector. Did the Batt Temp Sensor voltage change from below 1.0 volt to above 4.5 volts? Yes --> Replace the Battery Temperature Sensor. Perform POWERTRAIN VERIFICATION TEST VER - 2 . No --> Go To 3 |
All |
| 3 | Turn the ignition off. Disconnect the C3 PCM harness connector. Measure the resistance between ground and the (K25) Batt Temp Signal circuit at the Battery Temp Sensor harness connector. Is the resistance below 100 ohms? Yes --> Repair the short to ground in the (K25) Batt Temp Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 2 . No --> Go To 4 |
All |
| 4 | Measure the resistance between the (K25) Batt Temp Signal circuit and the (K900) Sensor ground circuit at the Battery Temp Sensor harness connector. Is the resistance below 5.0 ohms? Yes --> Repair the short between the (K900) Sensor ground and the (K25) Batt Temp Signal circuit. Perform POWERTRAIN VERIFICATION TEST VER - 2 . No --> Go To 5 |
All |
| 5 |
NOTE:
Before continuing, check the PCM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary. Using the schematics as a guide, inspect the wire harness and connectors. Pay particular attention to all Power and Ground circuits.If there are no possible causes remaining, view repair.RepairReplace and program the Powertrain Control Module per Service Information.Perform POWERTRAIN VERIFICATION TEST VER - 2 . |
