Toyota Corolla Cross: Generator Phase U Current Sensor Circuit Short to Battery (P0E0012,P0E0014,P0E001F,P0E0412,P0E0414,P0E041F,P0E0812,P0E0814,P0E081F)
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:
Internal inverter malfunction- Inverter with converter assembly internal circuit malfunction
- The connectors are not connected properly
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.

- When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for 2 minutes or more.
- Turn the ignition switch to ON and wait for 5 seconds or more. [*1]
- Turn the ignition switch to ON (READY) and wait for 5 seconds or more. [*2]
- Depress the accelerator pedal of the vehicle with the engine stopped and the shift lever in P to start the engine. [*3]
- Drive the vehicle forward with the shift lever in D for 5 m (16 ft.) or more. [*4]
- Drive the vehicle backward with the shift lever in R for 5 m (16 ft.) or more. [*5]
HINT:
[*1] to [*5]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Enter the following menus: Powertrain / Motor Generator / Utility / All Readiness.
- Check the DTC judgment result.
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
- If the judgment result shows INCOMPLETE, perform the normal judgment procedure again.
