I've been getting the P051B code for about a month now. It will come on, last a day or two, go away for a few days, then come back on. Truck runs normal and all seems good with it. Just wondering if anyone has had this code keep recurring and what it took to fix it as I am out of warranty. I've seen a couple posts about this code but nothing real helpful. Any information would be appreciated. Thank you.

 

what engine?

 

Sorry, 2016 with 3.5 ecoboost.

 

Its probably the crankcase pressure sensor that is bad, sold a few of those

 

Do you have a part number for it? I've tried googling it but couldn't come up with one. Or do you sell them?

 

FL3Z-6758-A

should be it

 

I had that part number already but thought it was just the tube assembly. Does it include the sensor with it?

 

yes, that is the only way to get the sensor

 

Ok thanks I'll try that. From the thread https://www.f150forum.com/f118/how-f...r-code-398449/ and the 3rd post down he indicated he changed the tube and sensor separately it seemed like so I wasn't sure.
