Q: im having the code p0088 and i need help

asked by on

i was driving my truck and this code came up when i checked the light on the dash and i dont know what it means or how to fix it

My car has 130000 miles.
My car has an automatic transmission.

Hello. P0088 is the trouble code for "Fuel Rail/System Pressure - Too High." If the computer detects that the fuel system pressure is too high it will set off the check engine light to notify the driver of this issue. Excessively high fuel pressure can cause performance and emissions problems, and in some cases can even cause harm to the fuel system components. Common causes for this code are a faulty fuel pressure sensor, or a faulty high pressure fuel pump. The fuel pressure sensor the system fuel pressure and can set off the check engine light if it goes bad. The high pressure fuel pump is the component that takes the fuel from the tank an re pressurizes it to the higher levels required for the system to operate properly. There is a check valve in the pump that can sometimes get stuck and cause the fuel pressure to increase to excessively high levels. In most cases the pump will have to be replaced in order to resolve the issue. I would recommend having a professional technician, such as one from YourMechanic, come to your location, to diagnose the specific cause of the check engine light so that the correct repair can be made.
