P0797 Pressure Control Solenoid C Stuck On High
The P0797 code means pressure control solenoid C in the automatic transmission is behaving as if it is stuck in the on position. It is usually caused by dirty or degraded fluid, or by wear in the valve body. The transmission can slip, shift harshly or drop into limp mode, so have it checked soon.
