I have been searching all over for what P0148 code means. so far it looks like maybe something to do with the fuel system. I am not totally sure, does anyone have any idea what this code is?

background; I was using my performance tuner through my OBD II, but before it programs it runs a scan for existing codes. This is how I found it. I think I hit the rev limiter a couple of times prior to this, so maybe the that had something to do with it.

truck: 2008 f150 4 x 4

It's a fuel delivery error. There's a bunch of things that it could be. Fuel filter, line blockage, injectors, etc.

Change the filter, run some injector cleaner, and test the fuel rail pressure to start.

It's as easy as using Google. Type in the code in the Google search window. Here is one of the Google search results for your code:

thanks for the help all, it seems that the truck sucked in air when it was ran down to fumes and made a right turn. So basically running out of gas at some point will leave you that code as well.

That'll do it too, lol.
