Have you taken the egr valve out?
The first thing to do is to remove the egr valve and see if its full of carbon. If it is clean the valve and reset the light. If the light comes back on then replace the valve. If there is no carbon build up on the egr valve then replace the egr valve. The code p0401 is the first code to fix as it will set the p006a code
how long does it take to remove the egr valve?
if the valve is full of carbon what do i use to clean it?
Not long at all. It is located beside the fuel filter on the top of the motor. Just take both 8mm bolts out then take a pair or channel locks to twist it and pull. If it will not come out you may have to use a pry bar to take it out
is this a common problem with my truck?
Yes its very common for egr carbon build up or egr valve failures
I would sugeest blowing the truck out from time to time. Like floor it so all the carbon will blow out the intake and exhaust
i started having the problem after pulling a big trailer. it blew abunch of stuff out of the tail pipe and shortly after that the codes came up.
Was it black smoke?
thick black smoke
Yeah i would take the valve out and look for alot of carbon. Sounds like either the valve is full of carbon or the turbo is. Do this remove the valve and clean then reset codes. If it comes back replace the egr valve and put in fuel conditioner. If you are still having this issue then the intake might be full of carbon. But alot of the Ford cetane fuel conditioner will clean it out
is there a way to clean the carbon out of the turbo?
im pretty good at using a cetane booster from amsoil
The turbo if bad will need to be removed and taken apart. But do the egr valve first
thank you very much! hope cleaning the egr valve will do the trick.
