Code P2D44: A/C Compressor Motor Performance
Diagnostic & Technical Explanation
Code P2D44 (A/C Compressor Motor Performance) sets when the electric A/C compressor's motor is stalled or is not achieving the rotational performance its commanded speed calls for, apart from any voltage-sensor circuit fault. A seized compressor due to internal mechanical failure, insufficient refrigerant/oil lubrication starving the motor, or a failed drive-stage component inside the compressor's integrated inverter are the common causes.
