Normal Operation and Fault Conditions
The generator current sensor is a hall effect sensor attached to the generator B+ cable. It is supplied a 5 volt reference and ground from the PCM. The PCM reads the generator current sensor feedback voltage to determine how much current is flowing through the generator B+ cable.
DTC FAULT TRIGGER CONDITIONS
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| P0A5A | Generator Current Sensor Circuit Range/Performance | This DTC sets when the PCM does not detect current through the generator current sensor and there are no generator current sensor circuit DTCs set. |
| P0A5B | Generator Current Sensor Circuit Low | This DTC sets when the PCM senses lower than expected voltage on the generator current sensor feedback circuit, indicating an open or a short directly to ground. |
| P0A5C | Generator Current Sensor Circuit High | This DTC sets when the PCM senses higher than expected voltage on the generator current sensor feedback circuit, indicating a short directly to voltage. |
