How do you get to the damn O2 Sensor?????

2006 JGC Limited 5.7L HEMI. Code P0138 says Bank 1; Sensor 2.

There's no room for a ratchet/breaker bar and I can barely get to the connector because my hand can't bend in 5 different directions at the same time!

Short of cutting the exhaust, is there an easier way to change the damn sensor? Any tips or tricks??

Re: How do you get to the damn O2 Sensor?????

From my experience....you can't! See my related thread about this subject:

What is easist way to access O2 sensor connectors?

I ended up having the dealer replace the bad o2 sensor for $180. They did not drop the mid-pipes for access as I would have needed to do. They either have special tools or employ 'stretch armstrong' to reach it. Best of luck.

Thanks man. I was starting to think no one was going to answer. Since I can see the sensor and the connector, I'm going to brainstorm which I usually have to do with low money funds... which seems to be a lot of the time.

Yeah, I usually do the same since I attempt to do most of my own maintenance and repairs. But this one stumped me. I was able to painfully get my arms/hands up in there to disconnect the connector (which has a damn lock). I even got the special o2 sensor socket but could not figure any way to get the handle in place or somehow otherwise grip the socket to remove it. After a couple hours I gave up and paid. Let us know if you come up with something creative to do this.

After replacing my motor, I had the mud pipes out and replaced the o2 sensors lol. It was a nightmare to disconnect them. The wires are way the hell up wedged between the body and the tranny. Freaking nightmare. I had to cut the old sensors out.

Well, you'll never believe this. After having my Check Engine light on for about 9 months, today it just went off. I thought the light burned out, but the light is still there when I start the jeep.

Re: How do you get to the damn O2 Sensor?????

By some contortion trick I am able to disconnect and re-connect the rear sensors and also remove and replace. But not easy.
Want to tackle the front ones in near future, but will first look for a more suitable 22mm spanner or else have one made up.
For the connectors, I use long nose pliers and flat screw driver to unlock and disconnect and re-connect.
