DTC codes / P28xx · Transmission / P281C
P281C indicates that the transmission control module (TCM) has detected an out-of-range or performance fault in the electrical control circuit for pressure control solenoid H, which is one of several shift and line pressure solenoids inside the automatic transmission. The TCM monitors the solenoid's commanded current versus the actual current or the resulting hydraulic pressure and sets this code when the circuit's response falls outside the expected window for a calibrated period.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
