I think I've got a poisoned/dying O2 sensor -- car runs rich at idle, trim values are wacky, and voltage response seems sluggish (on one bank only).

Here's my question: Other than cable length, are there any material differences between the signals and functioning of Bosch-style 5-wire (wideband) O2 sensors?

My understanding is no -- they all report O2 levels on the same reference voltage basis, but I want to confirm.

I'm asking as I've got a brand new 02 sensor in my parts bin that I could swap in -- but it's for a different car and is a different part number. Other than a different colored cable insulation (blue vs black) and the length being about an inch different, the two sensors otherwise appear similar.

Thanks!
