04 trouble codes

Recommended Posts

On the 04 it is showing a P0088. Says fuel rail/system pressure-too high. The next code is a: P0251 injection pump fuel metering control A(cam/rotor/injector). Any ideas on what these error codes represent? What do we need to do to get these cleared out of the system? Thanks for your help in advance.

Yep, its what meters the fuel to be pressurized. If its failing and allowing too much fuel in then you get too much pressure.It's located on the back of the CP3, and it has the only electrical connection on the CP3 attached to it. I am not aware of any real ways to test it. I hear if you shake it and it rattles its good?? But I am not sure I trust that..
