Default Car external temperature sensor location?

Huge gurgled happily, sounding much like they
were saying:

Anyway - most cars don't have an inlet air temp sensor these days -
they measure the mass of the incoming air instead via an air mass
meter rather than air flow meter plus inlet air temp.


Have installed both Megasquirt and Omex ECUs in the recent past, I can
assure you that both these systems have inlet air temperature sensors.
You need them for cold start enrichment, for one thing. (And the Omex
on my TVR doesn't have an air mass meter, either - it does fuelling
solely on throttle position and lambda.)


Yes, they do.


"Yes they do", what?


"Yes, they do", in a "Yes, those two do have IAT sensors" kinda way.

A couple of unusual and very specialised systems which do doesn't
disprove "most don't"
