QuestionI need a downstream oxygen sensor, because I continually get the 0136 and 0141 codes back on, shortly after they are cleared. The garage I normally take it to has my car down as being 1.6L (DOHC), where I know that it is a 1.5L (SOHC). I've told them, but it keeps showing up. What I was wondering: Is there a difference between the oxygen sensors in a 1.5L and 1.6L? If they get an oxygen sensor for a 1.6L, will it work in my car? I'm just wondering, in case they do order the wrong kind.
Also, is the downstream oxygen sensor (rear), the one by/on the front flex pipe I would have to get under the car to get at, or is it the one I can get at by lifting the hood? Are they the only two o2 sensors, or are there more?
I normally take it to a garage, because they seem to be cheaper than the dealership. The dealership quoted me $451, while the garage quoted me $240. I'd rather save the money, I just want to make sure the right part gets put in.
Thank you,
Gerald
AnswerThe downstream oxygen sensor is the one in the flexpipe under the car. The sensor in the 1.6 is the same as the one in the 1.5, so there shouldn't be any issue with the information mix-up in this instance.
If you're going to try to do this job yourself, make sure the wiring of the new sensor is routed so it won't rub on the axle shaft.
