hey guys got a problem with my car and which i think its the oxygen sensor. its on a 95 dohc my car only has one, i bought a universal one last year from autozone but now i tested and it says on the manual if you get it to normal operating temp it should go up and down on the voltage reading on the multi meter when you rev the engine. i get a constant reading that does not change. when i run it with it off i dont get a code and the car runs a little better. would this mean my sensor is dead? just checking before i buy a new one

well, i just changed mine n it seems to run better, i got a universal bosch one from advanced auto n it seems to work perfect, r u sure the connection is good?

ya im pretty sure its plugged in right, i just think all the work ive done to it, the timing, messing up the air fuel ratio bad fuel pumps and dumping fuel into the engine maybe burned it out. ima try tightening it see if that works maybe its not fully in there.

o well since uve done all that id replace it...its only $20 at advanced auto for a bosch one....it works good for me..

No, it's 20 bucks for you, not for us.
You have a single wire O2 sensor, our 94+'s have a 3 wire.

it's no less than 75 for a replacement at autozone.

autopartswarehouse has a replacement for about 40.

o my bad...sry bout that

It's still not too bad, we still get off cheap. Our situation could be like the newer vehicles. My friend's '05 eclipse has two O2's in front, and 2 in back of his cat.

Imagine trying to replace all 4 of them :S


75x4=300.

I'll pass. kthxbye

ya i no rite..that must suck..lol

if you can wait a week for shipping, you can pick up an oem oxygen sensor off ebay for around 50us. Oem is alot better than the universal ones.

ya thats what i was thinking, i had a universal o2 sensor and it crapped out pretty quick on our old saturn. thanks for the help guys i ran into other problems so the o2 sensor has to wait.

wat happened?

well either my new front main seal went or my valve cover or my cam seals because i got a ton of oil everywhere on the belt side of my engine. and i gotta get new seals and new timing belt.

o crap!!!! thats no good...usually the valve cover leaks but not a ton....its visibly but not a large amount....

Does anyone know, can Oxygen sensors be cleaned for maintenance or improved performance (perhaps with CRC Electronic Parts cleaner)?

im not too sure..but im guessing u would b way better off by just buying a new one..i mean u can always try..lol.
