Threw a code P0442
#11
OK - so here is the latest - I went to the stealership to pick up my part. The parts guy was pretty nice & let me open the box first - The part was not what I was thinking it was. So He & I go out to my truck & I point to what I think is the NVDLP. He said no - that was the purge solinoid.
Well between the two of us we couldn't find the NVDLP. Now I just had my right shoulder rebuilt 9 days ago - so I'm still pretty sore & not able to lift anything or do much with that arm. So I decided to just have the dealership fix it.
The parts guy takes me back to the service guy - I told him I just wanted this part installed & don't sell me a bunch of crap.
He called in the tech & between the two of them they start telling me how it could be any of 100 different parts or issues & they really should do a full smoke test blah blah -
So I guess they saw my eyes roll back in my head because the service guy says - why not just replace the gas cap - 90% of the time this is what he finds the issue is. Then the service guy chimes in that he has only see 1 or 2 DLP's in the 6 years he's been there. THey don't fail too often.
Plesently surprised I buy a new gas cap - reset the codes & so far we have been all good.
I'll let you know if I have any other issues - but so far so good.

Well it will be good if a new gas cap does fix it. A new gas cap didn't fix my evap leak, the P0442 came back on the next day after I bought and installed a new one. It was after that when I read about LDP failures, I read on several sites that the LDP is very often the reason for a P0441, and it made sense because of my wreck. You have a P0442 which is for a small evap leak, so maybe it was/is the gas cap causing the problem.
That is the problem with P04xx codes, there are a lot of different reasons and causes for the same code. Drive the truck a couple of days and see if the code comes back. Hopefully a new gas cap really was all you needed.
