changing the o2 sensors is a PITA!!

[jeep-N-montero]

For those of you who have changed them on your OBDII Monteros, did you learn any tricks? For those of us with big hands there isn't much space between the body and the transmission where they plug into the main harness. Took me 2 freaking hours when it should take 20 minutes on most cars.

Which sensors are you talking about, upstream or downstream? What type of O2 sensor socket did you use? This is a job I'm going to do this weekend.

I did both up and downstream, used a regular o2 socket from Autozone. The sensor itself isn't the issue, it's where the sensor plugs into the harness up in between the body and the transmission/transfer case, there isn't much room unless you have tiny hands. You will see what I mean when you get in there. I hope you stuck with Denso sensors or you are likely to have issues, I found a vendor on ebay and bought both for around $61 shipped.

I think I'm going to need to do this soon. My Monty has a cracked exhaust manifold, and now the CEL is on. I suspect the O2 sensor is being fouled, but I'm just guessing. Replacing the manifold looks like a real PIA

Seems like most every job on these trucks is a PITA to do. Lucky for us things don't fail to often.
I did an O2 sensor on my LS a couple months ago and it took me a good 30 minutes trying to manuver in there.

Good excuse for a body lift.
