OBD-II: On-Board Diagnostics, a system that monitors vehicle performance.
Drive Motor: An electric motor that propels the vehicle.
• P2DAB
• P2DAD
This code means there's a problem with the sensor that checks how hot the electric motor is getting.
The P2DAC code is triggered when the vehicle's computer detects an issue with the circuit of the temperature sensor for Drive Motor A. This sensor helps monitor the motor's temperature to prevent overheating.
The Drive Motor A Temperature Sensor B is responsible for monitoring the temperature of the drive motor. If the sensor or its circuit malfunctions, it can send incorrect temperature readings to the vehicle's control module, potentially leading to performance issues or motor damage.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the temperature sensor for proper operation.
• Replace the faulty temperature sensor.
• Repair or replace damaged wiring or connectors.
• Clear the code and test drive the vehicle to ensure the issue is resolved.

Sensor Issue
• Do not ignore the Check Engine Light.
• Have the vehicle inspected by a professional if unsure.
• Avoid driving the vehicle hard until the issue is resolved.
Check with your vehicle manufacturer for specific warranty coverage related to sensors.
This code has been associated with electric and hybrid vehicles as they rely on precise temperature monitoring for their drive motors.
Moderate – It is important to address this issue to prevent potential overheating of the drive motor.
Driving with a malfunctioning temperature sensor can lead to motor damage and is not recommended.
• Vehicle at operating temperature
• Engine running
The Drive Motor A Temperature Sensor B is typically located near the drive motor, which may be in the engine bay or under the vehicle.
Q: Can I drive with a P2DAC code?
A: It's best to have the issue checked as soon as possible to avoid potential damage to the motor.
Q: What happens if I ignore this code?
A: Ignoring the code could lead to overheating and damage to the drive motor.
