Question

I have to replace it before the c.c. blows...

also, does anyone have any advice on replacing a egr valve and sensor on an 02 explorer (4.0 V6)...

Answer 1

Dear Blazer-

There are several of them on this particular vehicle.

There will be one located on each manifold, then one before the catylist and one down the exhaust after the catylist.

The other respondent is correct in telling you they can be a real pain to remove.

But I do need to ask you what makes you think the O2 Sensor is bad. I have worked for Chevrolet for a few years, maybe I can help you out a little better if you could give me some more information and details on the problem you are experincing.

You can email me directly if you like, my email address is available on my profile.

Answer 3

the o2 sensor is located on the exhaust pipe, between the exhaust manifold and the catalytic convertor. It can really be stuck on there so be ready with the proper tools.
Pick up a repair manual like a "chilton" guide at the auto parts store. They run less than $25 and more than pay for themselves.
