Re: Tune Up

Is there a "Moron of the Year" award on this forum? If so... I humbly nominate myself

So, after removing the new sensor... and installing the old one... I was still getting the code. I tried clearing it, but it came back. I jiggled the harness, hoping whatever contact was being made would cease, but the code remained. I brought out the test light to see if any power was getting to the pigtail. It must only power up with the engine on because I was getting no signal from any of the pins... and I wasn't about to stick my hand up there with it running. Finally, I reached up there at an odd angle and decided to see if I could get any better connection. I felt it compress just a tad bit more. I cleared the code & restarted the engine.

YAHTZEE! Of course, had I tried that before, I wouldn't have wasted any of your guy's time.

Thanks for all the help. I do have another mystery though. A disconnected ground strap dangling from the transfet case. I'll post a pic.

So it did just need to be tighter? But its fixed now and the jeep runs like it Should?

Post the pic and I'll dig underneath my jeep to see where it should go.. anyways glad you sorted it out.

Ahh, the sometimes humbling "joys" of DIY wrenching we all encounter

Kudos for the closure !+++

Yeeeahhhh... and get this: The harness wasn't broken at all. When I re-installed the new sensor (and was able to actually get to the harness this time) it snapped onto place.

Of course, it'll be a bitch to replace now that I have to figure out how to undo the connection one handed.

Yep.... I deserved that. The sad thing is I'm really not a noob. My username is from my 68 Plymouth Fury that I rebuilt the engine, trans, & rearend in my garage... only thing I couldn't do myself was machine the block & balance the rotating assembly (no tools). I do all the maintenance I can on my cars. My 2005 Volvo S60R has more wrench room in the engine compartment & underneath than this Jeep. That's why this is so embarassing! LOL! I guess I should have expected it from a car with an engine that needs 16 spark plugs.

Anyways, here is that mystery ground strap. The picture was taken from the rear looking forward:


It was definitely torn from wherever it was connected to. I checkd within its "reach" and couldn't see any other bolts with the other end attached to it.

And a pic of the old 02 sensors. Couldn't find the other one after it was thrown into a bush... But it looked just like the one on the left only all the threads were jacked up:

Ohhh dude. Yeah these jeeps are beastly to work on. Imagine having to pull the front diff, trans, transfer case, exhaust manifolds, engine, suspension, rear diff, and you get an idea of how much I've had to do on my jeep in my garage. I pretty much know these cars inside out now.

Oh yeah and that ground strap that's torn bolts to the crossmember on one side and connects to the frame. No worries it's torn on mine too.

Re: Tune Up

Ok, cool. At one point a I was hoping it had something to do with the sensor failing! Lol.

Next job is replacing the front passenger CV axle boot. It's torn & is splattering grease everywhere. Plenty of room around that part... but I have faith it'll be a pain in the ass as well.

Oh it is... Getting that circlip in and out of the diff is either extremely difficult or sometimes easy. I have had to do it 5 times.

Re: Tune Up

Not sure why this ground strap is overthere, but i would replace it if i was you. It was not there for nothing and not having it there can result in a return current seeking its way through some other (unwanted) path.

I agree. I'll pick up a new one & figure where the other end attached too.
