I took my catch can off also never had much in the can ..

 

Is there any comments on the fix for this code anyone ???

 

Reading back through, it seems you're needing to rewire the connector?

 

thats my guess try to replace some of the wire its so small diameter but it has to be the issue a sensor just doesnt go bad all the time ..

 

ok after a lot searching if anybody else thinks they need a new pig tail here is the ford part number wpt-1308 cu2z-14s411-ava I will get one and see what happens

 

So last night I took pig out and tried to secure wires better, put back in sensor, and cleared codes, went to start truck & now a wrench symbol on dash I just shut it off did not look to see what code it was throwing now, as I hopefully will get my new pigtail today from dealer, and I will try to get it put on this weekend, and see if it works..

 

I picked up new pig tail not yet put on I played with wires in orginal one just to see if I can stop engine light from coming on, and I was not able to, I am scratching my head on the pictures I have form earlier post on wiring colors, I dont even know if I have them right, the picture that was posted with plug is diff year but I would think they should be the same ?? then you look at the pig tail 1 should be yellow, and 2 should be ye,gr and 3 should be gn,vt so when I have it plugged into sensor the yellow should be first one on top left to right ? I get a engine light with the key on dont even have to run the engine, I will start it and engine light right away for code po51b ... or when looking at plug when in sensor should yellow be on the far right then go left from there no one ever showed a picture of the plug off a 2019 ecoboost 3.5? once I threw 2 codes po68a came up also.. I checked the pcm relay with electrician at work it appears good ..

 

come on boatwaco you can help ? also just so anybody want to know I only use oem sensors thanks..

 

Look back at post #10…

 

Ok. Let’s start fresh. You have a new pigtail, right? It is to connect to the sensor, right?
Please post a few photos of the wires in the truck and the pigtail that you bought. We will go from there…

 

I dont want to hook up pigtail until im 100% on what color goes where post #10 shows yellow starting at right going left if im seeing it right ? not how I had it before, I think I had it the way the other picture shows of diff year, and it worked for a year ?

 

when you look at post #2 diagram doesnt make sense as where it goes on post #10 it shows #3 wire in the middle but I dont know how to read that ? post #2 shows it going from 1 23 downward which hooked up would be left to right on top ?

 

Please post pictures of the pigtail and the wires in the truck.

 

I have three wire and they are just hanging there right now I dont drive truck to work, I have a yellow a yellow green and a green brown or velvet whatever the last color is, why do you need pics they are just hanging.. another words they are not in the pig tail right now..

 

ok I figured how do download pictures lol, this setup is not right I dont think should 1 and 3 be changed ?

 

the replacement pig tail from part number I got from ford which is the same as anywhere the 3 wires are all green..

 

All I can find in my wiring diagrams for 2018 - 2019 Work shop manual wiring diagrams is that the Crankcase pressure sensor wiring seems to match your crankcase position sensor wires.
The Pressure sensor connector is in the lower half by the blue star. The wires are as seen coming out the back.
Perhaps the Green-Violet looks Green-brown.

 

Here are the C1120 position sensor and C1088 pressure sensor connector diagrams

 

well it shows like i said before the picture I have 1 and 3 switched and yes the gr vt looks gr br

 

are your colors diff on your 2018 ?

 

I don't know. I am only looking at my physical wiring diagram book and the PDF wiring diagrams - while I am listening to work meetings.

 

cant somebody with a 2019 post a pic of there pigtail please!!! as I want to see if it matches the diagram ? thanks..

 

When in doubt ohm out through the factory harness. Or use a multimeter to confirm which wire is which.

I did not. Probably just gonna replace the harness. Do you happen to know which one it is? I see many harnesses listed and am afraid I’m gonna end up with the wrong one

well if you look at my other post I gave the part number to pigtail hey boatwaco I said I got my part from ford dealer of I switched wires 1 an 3 and no light drove around block no engine light, so no pigtail needed. so looking at my picture yellow is on left, and gr-vt on right.. anyway thanks for help..

 

FYI - Ford will sell an entire harness, but typically they do not offer “pieces” of said harness. You can buy harness kits (as I call them) that have the right connector or, importantly, the right connector metal pins. These often come with one set of wires, all the same color.
So? Well, if I wanted to replace a section of harness that was broke, I would get the whole harness and replace it. I would not try to add on just a section. My preference. To me, it eliminates a lot of potential shorts or bad splices.
Just the way I do.

 

If you having an issue with one section of the harness, the rest of the harness is pretty worn as well. You can prevent future issues with a new one.

 

I get what your saying but I'm not having wiring issues anymore, besides to buy a whole harness just to get 2 inch of colored wire probably hundreds of dollars the pig tail that is offered is same part just all green wires, but I get it hopefully mine stays good I also dipped some electric tape glue in the cavity so it will hold wires better non the less I now know where the wires go I am a tool maker not a electrician lol... I also do all my own work my brother in law is a mechanic and never touches my vehicles..

 

my brother in law is a mechanic and never touches my vehicles..

I hope he's OK with that 1 star review...

 

dont I get a 5 star for fixing my truck

 

Anytime you can save money rather than give it to the mechanic is a great day!
