Right, thats what i thought...but i wasn't sure if it had 2 o2s or just used 1 to get cat deficiency readings and a/f.

Thank you. Now, is there only 1 o2 sensor? Let me make sure i read this right...if the voltage(at the o2) is staying at .1 or less...its shot...if it bouces around, its ok. Right?

Neither. Its throwing engine lean code....i don't remember the exact name or the code. But something to do with engine lean. Which i would assume it thinks that because the o2 sensor is shot and not reading right. But i could be wrong i guess, i just dunno what other sensor could let the ECU...

Ok guys, need some quick help here. I have had a check engine light on for quite a while on my 99 ltd 4runner. Now, code its throwing is "engine lean" code. The thing has had horrid gas mileage since. I figure its the o2 sensor, but would like someone to confirm it or say what else it could...
