P0988: Transmission Fluid Pressure Sensor E Circuit High
The P0988 fault code indicates a problem with the 4C (4th clutch) pressure switch in the transmission system. This code is triggered when the switch is either open or closed at the wrong time for a specific gear. For instance, if the 4C pressure switch activates while the transmission is in second gear, the code will be set.
When this fault code is detected, the transmission system will initiate an immediate shutdown routine. It is important to address this issue promptly to ensure proper functioning of the transmission.
FAQ
