DTC P0A00-1C: Motor Electronics Coolant Temperature Sensor Circuit Voltage Out of Range [12/2019 - 11/2023]: Description
WARNING: This page is about a different variant/trim than selected.
The motor generator control ECU detects the HV coolant temperature using the HV coolant temperature sensor built into the inverter with converter assembly. The motor generator control ECU uses signals from the coolant temperature sensor to check the effectiveness of the inverter cooling system. If necessary, the motor generator control ECU will limit inverter output to help prevent inverter overheating. The motor generator control ECU also detects malfunctions in the sensor based on the HV coolant temperature sensor values.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Warning Indicate |
|---|---|---|---|---|---|
| P0A00-1C | Motor Electronics Coolant Temperature Sensor Circuit Voltage Out of Range | The actual inverter coolant temperature is high and the difference between the estimated inverter coolant temperature and the actual temperature exceeds a threshold for 10 seconds, or after a long soak, the inverter coolant temperature sensor value differs from the values of other sensors.
