Hello folks. 1999 ford f-150 v8 5.4l lariat, 217,000 miles.

Today my engine light came on and I hooked my scanner up to it, and it fired off some bizzare codes. I cannot seem to find these codes anywhere on the net. O have also never seen a code on my truck that did not start with a 'P'. What the reader told me:

U09C9
B3D5B
U0B50
C1BC9

Anyone seen codes like this? Are they actual codes or some sort of computer 'burp'?

 

i've seen codes similar to that from a volkswagon. but right next to it it has the "P0" code in parenthesis. i dont think those are the real codes.

 

It's weird. I have been chasing down a p0171/p0174 code, so i have one of those scantool things always hooked up to the odbII port. When the light comes on, i check the code real quick and erase it. This time I had the p0171 along with those other weird codes. It's gotta be some sort of misread.

 

do you think the weird codes will come up if you were to try it again?
for the P0171 and 174 did you check you pcv tube and elbow?

 

I am going to erase it and see. Hope its nothing major, I am driving across state tomorrow for a music fest.

Actually, yeah, I did check it. Its weird, the elbow part was not cracked or anything, but it seemed to simply not 'fit' on the nozzle. I could flick it off with a finger. I pulled it off the hose and reversed it, and it fits a little better but not much. So its sort of sitting there while I hunt down a new elbow, the advanced auto parts people were no help.

 

Get the whole PCV assembly from Ford. I think it's about 35 bucks.

 

Yea it's $49 from Ford.
