The car's computer thinks the motor that controls the clutch is moving too slowly.
The engine control module (ECM) has detected that the motor controlling Clutch A is not spinning as fast as it should be.
The P28CA code indicates that the motor responsible for engaging or disengaging Clutch A is not reaching the expected speed. This could be due to a mechanical issue, electrical problem, or sensor malfunction.
