Battery Charger A Input Voltage Sensor A Circuit Range/Performance

Where it lives

For P0D3E, the part to look at first is the sensor named here.

Check these first

• A battery charger A input voltage sensor that has drifted out of range
• Reference voltage or ground at the input voltage sensor A is unstable
• Corrosion or water in the input voltage sensor A connector
• A chafed signal wire on the charger A input circuit
• An internal fault in the battery charger A assembly skewing the reading

What to do next

1. Read the input voltage sensor A value on a scan tool during charging
2. Compare the reading to a meter at the charger input
3. Inspect the sensor A connector and wiring for corrosion and chafing
4. Check the reference voltage and ground at the sensor
5. Replace the battery charger A assembly if the sensor circuit tests good
6. Clear the code and retest
