2001 Toyota Avalon Q&A
2001 Toyota Avalon Question: OXY sensor replaced twice within 1 month. OEM part Bank 2,sensor 1
Check eng light diagnosis - replace oxy sensor listed above. Had it replaced & after about 2 wks, chk eng light comes on again. Took it back & they replaced it again. Now it's been about 2 wks and the light is on again. Reputable repair shop. Also had diagnosis done at 2 different places and both showed sensor. what could be going on? - sfrisch8
What brand sensor was used? Were the circuits to and from the sensor checked? Lot of things can cause a sensor code but it aint always the sensor. A sensor is what it says, it senses a problem in a particular area and tells the computer, then the computer tells you. After that it is a matter of diagnosing and repairing the problem. Sometimes it is a faulyl sensor, sometimes not. - pushrod

Sorry to keep posting about this. I told my mechanic about the check engine light coming on again & he said he just didn't know, offhand but that he'd get it figured out. He only works on the weeke...
