Lol!

Well i moved out of nyc, and ive been busy thats why ... hahah

the front o2 sensor is atop the transmission where the engine and transmission meet. you can access the harness from the top under the hood from the left side.

:lol:

That's where the plug is...the O2 sensor is I'm the exhaust manifold ��

Not to mention that it was all covered earlier in the thread.

I almost hate to bring this one back after the earlier exchanges, but here goes anyway.

I need to change my front sensor on my '06. Have both the sensor and plug located just fine from all the info here - very well illustrated and my thanks for that. Plug will be tough 'cuz I have big clunky hands, but I'll likely remove some stuff to get in there - moving the A/C line may help and be enough as I saw elsewhere. The sensor is easy to get to since I have a lift in the garage and have it soaking with PB Blaster ahead of time.

Question I have is how do you get a wrench in there to loosen the old and then tighten the new sensor? I see there are two types of sockets, and I used the longer one a while back, when I swapped the rear sensor, but the shorter one is what I figure I need for this with the offset. Does anyone by chance have a pic of how the wrenches will configure in this space? I'll go rent the right socket when the new part arrives and I have plenty of ratchets, but want to have a better idea before I get too much further.

Thanks in advance for any help here!

Mike

Edit: I found this offset wrench on Amazon. Will this be the best tool for this job?

Update on progress: Moved the A/C line and got the plug easily that way. The socket won't budge the sensor at all, so I decided to just go ahead and start removing the whole manifold. Really taking my time with that, since I don't need the car right now. Broke one bolt on the lower mount bracket for the manifold and the bolts for the manifold to the CAT are pretty bad too. No big deal if those break. Soaking more with PB Blaster and giving it all time to sit so far.

The two bottom rear manifold bolts came loose pretty well so far and need to pull the front right wheel to get the engine mount bracket out, so I can get to the rest of the manifold bolts on top and bottom front. Once the unit is out, the sensor should be easier to finish off - then just reinstall everything to finish the job.

Have to admit that the start was ugly, but patience should get me through the rest.

Happy Thanksgiving everyone.

Just want to close this here. Appreciate the initial details given. For my case, I ended up having to pull the manifold to cleanly remove the sensor. The space was tight and the sensor was too stuck to get it to turn with any of the tools that I had to try. Here's the sequence:

Removed the motor mount on passenger side to help with access
Removed brace under the engine
Pulled the bolts from the manifold - they came off very well
Broke two of the bolts from manifold to cat so I had to get the studs out and get new bolts for that reinstallation - not a big deal there
The heat riser tube to the EGR valve was a pain to get out to remove the manifold as those nuts were rusted and I couldn't get socket over them to loosen. Cut the bolts off at the manifold and removed the other end up top to get the tube free
With help was able to maneuver the manifold out and remove the sensor
Got a tool to clean-up the threads on the sensor hole
Put it all back together and cleared the code with the OBD II reader.

All seems good now s far.
