Hey guys, Im not real familiar with Dmax trucks, so I need a little help. Had a customer tow a truck to me on Friday that would only idle, and was in reduced power mode. To make a long story short, it had a boatload of DPF codes in it because it was plugged. I pulled it off, and the truck runs better, but on a test drive it is setting a P0087 FRP too low code. Changed out the filter and cleared the codes, and the truck ran great for half a block before the change fuel filter message came up on the display, and the engine derated again. WTF!? I watched the fuel rail psi with my scan tool, and its not dropping. Im lost on this one. What else should I be looking for? I have ordered a tuner for the DPF delete. Is there any correlation between the DPF being mia and the FRP code? Thanks in advance.
