So who doesn't have O2 sensors? I was underneath my pickup today and thought about O2 sensors and how hard they would be to change if I ever had to change them, but I looked and I looked and could not find a single O2 sensor. Is this normal on a '95 360? Aren't they usually positioned between the headers and the catalytic converter? Well, I follwed the pipes all the way to the muffler and found nothing. I don't know if I should be bragging about this or concerned, I obviously don't know much about O2 sensors...thanks guys

 

should be in the side of the cat

 

see the hole towards the front......thats mine, 95 318

 

If you didn't have O2 sensors you would be throwing a CEL. Well unless you did the mod that is in the FAQ for getting rid of it but most people dont to my knowledge. Really the only way I can see that you wouldn't have O2 Sensors is if you had a Y-Pipe or something else that cut out the cat. I have Dual Straights on my 318 and I still have the O2 sensors in mine but it throws a CEL every 100 miles or so. Thank god for the code scanners so I can just get rid of it

 

okay that makes some sense because the cat is the one spot i didn't really think twice to see if there was anything so I'll have a look at it tonight. Thanks guys!
