Hello, is the code you are getting P0088?

Customer: replied 1 year ago.
I already knew the code. I wanted to know if there was some way to adjust the pressure or have to replace the sensor?
Expert:  James replied 1 year ago.

Im aware you know the code but I don't know which code you are talking about. There is no way to adjust fuel pressure on this vehicle. There are two ways to repair this concern. One is to update the PCM which changes the parameters that the sensors work at. If the PCM update doesn't correct the concern the only other repair is to replace the HPFP. The high pressure fuel pump is a complete assembly and the sensors on it can't be replaced separately. 98% of the time the high pressure fuel pump needs to be replaced to correct this concern.
