I do not know much about this vehicle. You might want to go get a service manual or get an all data subscription. (It’s cheap!)
The trio of crows bit made me laugh haha.For getting to the connectors I would try some really long needle nose pliers. I bought a pair ( straight and 90 degree ) from harbor freight many years ago. I believe they are about 14” long . use them all the time. you could also try hose removal pliers. as for the sensor its self , if a standard sensor socket wont fit you can pick up a crows foot style for your ratchet. also they make a crows foot style sensor tool with its own attached handle. hope this info helps.
Hi redfury,
What code(s) did you get please? Also, is it known what O2 sensor needs attention? When working from under the vehicle, do you have the vehicle raised up at all? I know sometimes a mirror can help too, especially when working in tight areas. I am looking forward to other’ posts, as well as hearing your progress. Keep us posted.
when i do them i usually support the exhaust in the rear and drop it down undoing the hangers gives you a little more space hope this helps
Well the only thing I can offer is ‘welcome to my world’. I’m not trying to be sarcastic but this is one of those things that you just get kicked in the teeth on I’m afraid but do enough of them and I’m sure you will become more proficient. The right tool might help but you may have to go through the access panel OR you might consider dropping the back of the transmission to gain better access.
Well, I worked on the Exploder today since the temps were 43F in MINNESOTA on December 18th! I’m taking that opportunity and making good use of it whenver I can!
Fortunately, it ended up being the easier of the two sensors that needed replacing ( bank 2 ), but I still plan to replace that other sensor since the code was for a sluggish sensor which makes me believe that the other one will start going sooner than later. Dropping the back of the tranny and the transfer case seems like just as much work as pulling the console and seat out or picking up some really long pliers and surgically getting that plug off.
Funny, the O2 sensor I was focused on originally loosened up for me no problem, the one that actually needed replacing ended up being the PITA automotive work is known to create. Took coaxing from penetrating fluid and the good old propane torch to get it to give up it’s grip on the threads. New Bosch O2 sensor installed and wiring properly zip tied away from the front drive shaft and the scan tool I have is showing me really good readings from both sensors, so for now I’m happy with the repair. However, this thread is far from over, the fight still continues, but I get to do it on my terms, which means I will do my best to document how I go about it for future O2 replacements searched for on the ETCG boards!
