CEL came on and the local Autozone said it was the bank 1 line 1(?) O2 sensor. Carwled under the truck to take a look and it's apparently the O2 sensor just after the passenger side manifold but before the first cat. Even if I could squeeze the wrench in there, I'm not sure how I would pull the electrical connector. Looks like I may have a little more space if I pull the heat shield, but not much. Any hints tips or tricks?

 

Here is a link from the how to and technical articals. I think it may help.

Awesome, thanks for the heads up!

 

tumba you dont know how long i was looking for that thread!

 

Haha, the search engine is not always so easy to navigate. I was searching for hours trying to find something on this.

I also looked for about 3 hours trying to find out exactly how to pull and clean the maf sensor on my truck. Finally found this link in another thread:

There's all kinds of stuff telling people to clean the sensor, but nothing on here about how to do it, unless you have an '05 which has it's own thread.
