ICEs will also use recycled exhaust to warm intake air. There's a separate sensor for intake air temp and I think a separate oxygen sensor that should inform the fuel mix.
At least in my performance car, there are separate gauges for engine oil, transmission fluid, coolant and air intake temperatures. Those are all exposed to me in dash.
I think traditionally, the only temperature exposed to the driver is the coolant temperature as that's usually the only one that really causes problems with overheating.
- walnutclosefarm 4y agoI am not current by any means with many makes of contemporary cars, but those I have had anything to do with used the coolant temperature sensor as the input to the fuel adjustment. I'm not saying that's universal, but it certainly is common, and makes a lot of sense if you're looking for a reading on the engine operating temperature, since that's what the coolant regulates.
