P0A2C Drive Motor A Temperature Sensor Circuit Low
Voltage at motor A temperature sensor below threshold, suggesting short to ground. 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 P0A2C?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyShort to ground
- Less likelyConnector pins corroded - high contact resistance
