The pigtail lengths are different, and the connectors are keyed, I don't remember what's what but placement listed on most FLAPS' websites.

The key in the connector can be cut off to make a "universal" fit sensor, the pigtail length is another issue--too long is OK, however too short can present problems ...

devon...that bosch only has one choice. will replace any o2 sensor on my car or what?

If your downstream 02('s) are/is bad you SHOULD be getting a Catalyst efficiency code.
The job of the Downstream (Rear) O2's are simply to measure the efficiency of the Cat's. If the voltage is wrong, a Cat Eff. code is thrown.

However, if it's an Upstream you should be getting TERRIBLE fuel mileage, the possibility of other symptoms and NOT a Catalyst Efficiency code.

well everyone is saying that it is a downstream one, but i am not getting any other codes... my gas mileage seems pretty ****ty right now...so whitch one should i change out..i dont want to buy all 4...it is running those two different codes...someone help me...all of this is just confusing me even more and more

justang97

codes are p0141 and p0136

LS WHAT

p0136, do you have a exhaust leak on the pass side exhaust near the o2sensor?

p0141, pass front o2 sensor needs replacing.

P0136 and P0141 are both Bank 1 Sensor 2 (passenger side, rear sensor) codes--click on the links to find out more...

Well according the the information in the listing, it will work for the front AND rear locations. So I would assume you would be safe there. Honestly though, if you can afford it, I'd replace em all. But thats just me.
