The P0A2C fault code refers to the Drive Motor ‘A’ Temperature Sensor Circuit being detected as low. This fault code is related to the resistance of the thermistor in the motor temperature sensor No.

1.

The resistance of the thermistor changes with the motor temperature, with higher resistance indicating lower temperature and vice versa. The motor temperature sensor No. 1 is connected to the HV control ECU, which supplies a power voltage of 5V to the sensor.

The resistance of the thermistor and the sensor are connected in series, causing the MMT terminal voltage to change with the motor temperature. This signal is used by the HV control ECU to limit the load and prevent motor overheating. The P0A2C fault code indicates that the HV control ECU has detected a low voltage in the Drive Motor ‘A’ Temperature Sensor Circuit.

This could be due to a wiring malfunction or a malfunction in the sensor itself. It is important to address this issue promptly to ensure proper motor temperature monitoring and prevent potential damage to the motor.

What are the possible causes for the automobile fault code p0a2c?

If you see the engine light or service engine soon warning light on, the fault code P0A2C could be the culprit. This code is often caused by a faulty hybrid vehicle motor, an open or shorted motor harness, or a poor electrical connection in the motor circuit. To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage or corrosion, and check for broken, bent, pushed out, or corroded pins in the connectors. Don’t forget to check the possible causes listed above for a more comprehensive solution.

How can I visually inspect the wiring harness and connectors to fix the fault code p0a2c?

If you’re dealing with the fault code p0a2c and your engine light is on, it’s time to visually inspect the wiring harness and connectors.
