P0A2D Drive Motor A Temperature Sensor Circuit High
Voltage at motor A temperature sensor above threshold, suggesting open circuit. The drive motor's position, current and temperature are watched continuously; a fault here downgrades the inverter to a safe operating point or triggers torque reduction.
Is it safe to drive with P0A2D?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyOpen sensor circuit
