Look at this and do the cleaning. Then you should be fine. clicky me

You need to make sure none of your boots are leaking. And check for soot on your up pipes.

Good luck.

could be a bad sensor..if you have a scan tool like AE..or if you can reads volts..then do a health check on the EBPS..here is the readings...

I just went through this same thing last week. Matter of fact just put the new sensor in Tues. They have an updated part number, I can get it for ya if you need it, mine ended up costing about $146.oo and another $56 for the tube if you need that (I didn't). When mine was out, it was throwing two codes, changing the sensor fixed both. And so far seems to have brought up the MPG. By the way, thanks again to F350-6 for helping me out on that one I'd prob. still be huntin' the problem if he hadn't jumped in with info.

I'll bet they were thrown BEFORE you cleaned it out. You got any way to reset the DTC's? What are the two codes, you remember? Ours were P0478 & P0470, that's not to say that those are the ONLY codes that a bad sensor can throw, but those are the two I had.
