3 O2 sensors fail at once?
Have you ever heard of that?
It apparently happened to my car. To be clear, it was both pre-cats and one secondary. |
My initial reaction is: possible but not probable.
And I don't mean to cast any doubt on the veracity of your statement, simply that those are some pretty long odds! |
I agree with you, hence my qualifier, "apparently".
|
It's not likely two would go at same time... let alone three
unless a bigger issue of major fouling is going on to ruin/coat them w/ something. Did you use a multimeter to individually test? |
Evidently they tested dead. There must be something else going on as you allude to.
|
I had both secondary sensors fail at the same time..... nobody knows why.....
|
I've had 3 go out -- but over a 5000 mile window -- do it your self - Rock Auto Bosch OE match < $100 each.
