HYBRID CONTROL SYSTEM, Diagnostic DTC:P0E33-589 and P0E34-590

DTC Code DTC Name
P0E33-589 DC/DC Converter Voltage Sensor "A" Low
P0E34-590 DC/DC Converter Voltage Sensor "A" High

DESCRIPTION

The MG ECU, which is built into the inverter with converter assembly, detects pre-boosting high voltage (VL) using the voltage sensor in the boost converter to control boosting. The MG ECU also monitors the boost converter voltage sensor signal line and detects malfunctions.

DTC No.
