Engine Code For 04 6.0
Hey guys im getting a P0470 engine code which is exhaust back pressure circuit error. Any one have any fixes or repairs for this problem.

Change out your exhaust pressure sensor. Could also check your pcm just to be safe. Is your truck running bad?
|
only sometimes it will run a little rough. just rev the rpms a bite other than that it runs great. what do you mean check the pcm. i just got the truck and aint learned much about them yet
|
You can try cleaning it first. There is a stainless tube threaded into the drivers side exhaust manifold, follow it up and the EPB (exhaust back pressure sensor) is there. Remove the sensor and the tube and clean both. They gum up with crap.

ok thank you i will do that tonight and get back to ya. thanks for the help. do you know how many ohms that switch is suppose to have.
|
I'm not sure off the top of my head. Pull it off and check it out, it's most likely gummed up with a bunch of gooey soot. Even if you could test the electrical side, it will probably be fine in that regard, me thinks. The issue is all of the crap on the other side of it.
|
Ya cleaned it out and it dont throw that code any more. thanks for the help.
