I should try and run a jumper wire, outside the harness maybe? Not sure where the other ends come out of the harness to. Can I just run a wire from the battery to the selenoid to cheat, to see if it get power, and clicks? or is that bad?

I didn't check to see if there was power going to the valve. There are two wires, "I forget the colors", i don't know which is the hot. i have a voltmeter.

Also. i am going to remove the canister. Maybe it is bad, and I can check it. I don't know if anyone sells them except the stealership though. I am in a pinch. i need it on the road so badly, and kind of in a bad situation. I am hoping it is not the computer...ugh!!!

 

So the wire, "one of them" go from the selonoid on the firewall", to the trans sensor, then the evap leak detection, then to the fuse box? i want to make sure I am understanding that right?

YOU NEVER GOING TO BELIEVE THIS!!
I checked the selonoid..No Power....Okay.
I checke dthe fuse box. There was "no fuse at all" in number 10 slot. I don't know if thats for this code. P0443. But I put a fuse in, and the disconnected the battery. And the damn engine light went out. The previous owner told me he disconnected the a/c casue it didn't work. He didn't tell me he was pulling fuses!! ugh!!
I guess I am good now....

 

Well Defiance! It sure wasa fuse number 10. There was no fuse in the box at all! He removed it. I cannot believe that! I put a fuse in, and its fine now. light went right out. Unreal! why do people do dumb ****! Thanks for the advise. I am going to run to advance, and get the codes run again, while I return the new selonoid that I didn't need.

 

I had several codes and this was one of them, mine turned out to be a bad vacuum line in the hard plastic preformed one, only found that cuz I have a vacuum tester and tested all my lines. replaced it and all is well. the vacuum line is located under the air filter in the far left of your pic with the big hose, I believe if you trace this back to the manifold it should be the first one, I ran a new "rubber" line. also replaced the rubber "flex joints" along frame/fire wall on drivers side since XJ has 137K on it. Sorry cant remember everything at this moment but hope I pointed you in the right direction. PM me if needed.

 

Thanks!! it was fuse numer 10. The owner I just boght it off of, removed the fuse completely. He said he disconnected the a/c, and thats when it came on. I think he pulled that fusing, "thinking a/c", and here came the engine light!
Whatta nut! I popped the number 10 fuse in, "15amp", that was sitting in the glove box, go figure! And the light went out.

 

hi I just changed O2 sensors on my 2001 cherokee I had a problem with cat converter , check engine light was on, obdII clean the code but the light is coming on and off , does anyone know how often those cat converters go bad...?
