HYBRID / BATTERY CONTROL: HYBRID CONTROL SYSTEM: P3227-583,P3228-584: Converter Temperature Sensor Circuit Low
P3228-584 - Converter Temperature Sensor Circuit High

DESCRIPTION

The MG ECU uses a temperature sensor that is built into the boost converter to detect the boost converter temperature. The boost converter temperature sensor outputs a voltage that varies between 0 and 5 V in accordance with changes in the temperature. The higher the boost converter temperature, the lower the output voltage. Conversely, the lower the temperature, the higher the output voltage. The MG ECU limits the load based on signals transmitted by the boost converter temperature sensor, in order to prevent the converter from overheating. The MG ECU also detects malfunctions in the wiring of the boost converter temperature sensor, as well as in the sensor itself.
