So I went in really deep water, truck died. I was able to start it up shortly after (while in the puddle) to get it out of the puddle and then I shut the truck off. Took the sopping wet air filter out then made sure no water was in any of the cylinders by cycling the engine with the spark plugs out (one at a time of course.) Luckily no mechanical damage to the engine that I can tell ------- yet.
Yes rookie mistake I know...........Now to the problem.
The truck was throwing a CEL for P0257 (something like that) and I changed the MAF. This solved the first CEL. Now the CEL is coming on "P0051" I looked into this on the forums already and have tried changing out fuses and I also just installed the URD o2 Sim.
None of my attempts to solve this have worked. Anybody have any advice?
