Maybe it's the hottest or leanest?
In our beloved vw bugs n°4 was the hottest because it was offset from the cooling air flow...

Thanks a lot :thumbup:

I've seen a stock exhaust from a certain car (don't know make or model)
It had a single wire O2 sensor and has another single wire coming from what seems to be a thermometer (what other sensor could it be?)
If it's a thermometer, what kind of signal could I read with my dmm?
Thanks in advance

So I should read ohms...
Thanks

Sorry if I wasnt clear enough
The O2 sensor was there
The second sensor in the same exhaust manifold could be a exhaust temp sensor?
I was talking about reading this temp sensor variation alone, without ecu

A diesel... Only cars I've seen there were gasoline
Both were located just after primary tubes merge
I'll get a couple pics
