DTC P3226-562: DC/DC Boost Converter Temperature Sensor; DTC P3226-563: DC/DC Boost Converter Temperature Sensor: Description
- The MG ECU located in the inverter with converter assembly detects the temperature of the boost converter using a temperature sensor built into the inverter with converter assembly. The inverter cooling system is the same as that for MG2 and MG1, and it operates independently of the engine cooling system. The MG ECU uses the signal from the boost converter temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the MG ECU will limit inverter output to prevent inverter overheating. The ECU also detects malfunctions in the boost converter temperature sensor.
