The factors influencing the cost of diagnosing and fixing the automobile fault code p0c28 are the estimated repair time of 1.0 hour and the typical auto repair shop charges between $75 and $150 per hour.

The P0C28 fault code refers to the Electric Transmission Fluid Pump Motor Current being low. This code is related to the Electronic Transmission Fluid Auxiliary Pump, which is responsible for keeping the transmission engaged when the engine is stopped and the transmission is in drive.

The Transmission Control Module (TCM) monitors the control circuit of this pump. If the signal from the control circuit is not within the factory specifications, the TCM will set the P0C28 code.

This code indicates that the current flowing through the motor of the electric transmission fluid pump is lower than it should be.
