DTC P0E00-28: Generator Phase U Current Sensor Signal Bias Level Out Of Range/Zero Adjustment Failure: Notes
- -
Detecting condition:
Generator inverter current sensor U-phase offset malfunction
When the absolute value of the current sensor output exceeds the specified value while no current originally flows such as inverter shutdown
(1 trip detection logic)
Trouble symptom:
- Reduced output power
- A driving range is limited
- Engine always stopped
CAUTION: Before performing diagnosis, refer to "CAUTION" in "General Description". Ref. to P-HEV DRIVE MOTOR (DIAGNOSTICS)>GENERAL DESCRIPTION>CAUTION .- CHECK DTC

No: -
- CHECK THE CONNECTING CONDITION OF CONNECTOR (Inverter with converter assembly LOW PRESSURE CONNECTOR)
.CAUTION: Make sure to wear insulated gloves and protective goggles during the work.
- Check that the Service plug is disconnected. Ref. to HYBRID ELECTRIC VEHICLE>SERVICE PLUG .
- Check the connecting condition of low pressure connectors (HV23) and (HV24) in Inverter with converter assembly and check the relevant terminals for contact pressure, deformation and intrusion of water or foreign matter. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY
.NOTE: When connecting the connector, insert to the end with the lock lever raised, then fold the lock lever completely until a click is heard. After connected, make sure that the lock claw does not loosen and pull the connector to see that it does not come off.
Is there looseness at the connector connection, or any poor contact, deformation or intrusion of water or foreign matter at the relevant terminals?
Yes: Connect the connector securely. Or repair the poor contact of connector.
No: Replace Inverter with converter assembly. Ref. to HYBRID ELECTRIC VEHICLE>INVERTER AND CONVERTER ASSEMBLY .
