While doing maintenance to the car last weekend, I noticed that the O2 sensor located on the exhaust was extremely dirty.

What should I use to clean it?

 

is it a g3 teg?

 

97 Teg

 

ok where is the o2 sensor located on the exhaust manifold for my 95 gsr?i only have one-obd1.
can you tell me?
i would guess electrical cleaner, not sure though

sorry im just trying to figure out where it is on my car and the only person that responded to my thread had a g2 car

 

o2 sensor are bolted onto the bottom of ur headers, near the cat, so that it can the burned exhaust to get a cleaner burn

 

can read'

 

thanx,so i guess i do have to lift my car up.

 

AFAIK, there is no official way to clean it. Cleaning solvent is a no-no since that will contaminate the sensor. Some of the pollutants can be burned off but it has to be in a controlled environment - You can't just bake the sensor :-p. Personally, I would suggest leave it alone, unless you are really getting crappy mileage. If that is the case, it may be worth it to buy a new sensor and see if that helps.

 

should i get a bocsh o2 senser?

 

yeah get a Bosch. That's what I got and so do a lot of people because it's quality and much cheaper than buying the OEM o2 sensor from the dealer.
