DTC SUMMARY
MALFUNCTION DESCRIPTION
These DTCs indicate that the current sensor value is abnormal. The cause of this malfunction may be one of the following:
DESCRIPTION
The motor generator control ECU (MG ECU), which is built into the inverter with converter assembly, monitors the generator inverter current sensor. These DTCs indicate the malfunction of current sensors and do not indicate a malfunction of the high-voltage system.
DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
---|---|---|---|---|---|
P0E0028 | Generator Phase U Current Sensor Signal Bias Level Out of Range / Zero Adjustment Failure | Generator inverter current sensor U phase offset malfunction: The absolute value of the current sensor output exceeds the threshold when current should not flow, such as when the generator inverter is shutdown (1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
P0E0428 | Generator Phase V Current Sensor Signal Bias Level Out of Range / Zero Adjustment Failure | Generator inverter current sensor V phase offset malfunction: The absolute value of the current sensor output exceeds the threshold when current should not flow, such as when the generator inverter is shutdown (1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
P0E0828 | Generator Phase W Current Sensor Signal Bias Level Out of Range / Zero Adjustment Failure | Generator inverter current sensor W phase offset malfunction: The absolute value of the current sensor output exceeds the threshold when current should not flow, such as when the generator inverter is shutdown (1 trip detection logic) |
| Comes on | Master Warning Light: Comes on |
MONITOR DESCRIPTION
If the MG ECU detects a generator inverter current sensor U, V or W phase offset malfunction, it will illuminate the MIL and store a DTC.
