P0748 HYUNDAI - Pressure Control Solenoid 'A' Electrical
- Dirty transmission fluid
- Low transmission fluid level
- Faulty line pressure solenoid valve 'A'
- Line pressure solenoid valve 'A' harness is open or shorted
- Line pressure solenoid valve 'A' circuit poor electrical connection
When a transmission solenoid is malfunctioned, in most cases the problem is not the electrical part of the solenoid; the problem is foreign material obstructing the mechanical function of the solenoid or the flow of the fluid through the transmission valve body. If the transmission fluid is dirty, it's recommended to change the transmission fluid and if possible removing the transmission pan for further diagnosis. Excessive debris or metal particles on the transmission pan could be an indication that there is a mechanical transmission failure and that the transmission will need to be rebuilt or replaced.
When is the code detected?
Engine Control Module (ECM) detectes an open or shorted condition on the solenoid circuit
- Engine Light ON (or Service Engine Soon Warning Light)
- Transmission shift shock
