"• Many sensors draw that reference air through the wire insulation and the crimped terminals, not through a visible vent hole.
2. The wire and terminal are designed to be slightly gas-permeable.
• The sensor’s lead wires are usually special “porous” or “vented” insulation."
...having in the past worked as an occasional electrician, mostly household factory installs,
I find this information to be astoundingly hard to believe. Shocking even !
I don't know if I should simply stand corrected or if I need to be skeptical of Chat GPT or do more research. The oxygen sensor wires are heat-shielded with a woven tube of fabric and they are about 1/2" (-2 cm) away from the exhaust pipe ( on my BMW M3 ) these wires have one job to transfer electric signals, never considered them having to breathe or to send air through the strands...but I get it: there is a difference between a crimped wire and a soldered wire.
Do wires breathe? Not that i know of, but I know they can drown.. ie they generally don't do 'great ' submerged in liquid.
