| 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 uses a voltage sensor that is built into the boost converter to detect pre-boost high voltage (VL) to allow boost control. The MG ECU monitors the boost converter voltage sensor signal line and detects the following malfunctions.
| DTC No. | INF Code | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| P0E33 | 589 | Open or short to GND in the boost converter voltage (VL) sensor circuit | Inverter with converter assembly |
| P0E34 | 590 | Short to +B in the boost converter voltage (VL) sensor circuit |
