How does a car run without an Intake Air Temp plugged in.

I searched and found lots of ppl trying to retorfit them onto aftermarket intakes, but I was mainly curious how it affects your performance? Does your car go into a somewhat detuned mode, or does it make a general assumption?

Thanks

So, is your plugged in or not?

If so, check for that code. You may have a malfunctioning sensor.

If not, plug it back in and see what happens.

I have that code, I assume it's not plugged in all the way, since I painted my pipes that plug takes a lot of strength to plug in, and my shop may have just forgot about it or not installed it correctly, at any rate I'll check when I get out of work.

Anyways, let's just say it's not hooked up at all, how is performance affected?

Re: How does a car run without an Intake Air Temp plugged in.

The value from the intake air temperature probe is used solely for diagnostic purposes by the ECU. It is not used in any way to adjust engine performance. If you unplug it, the engine will run exactly the same but the ECU will throw a code, that's it.

Ok thanks, I thought that perhaps if it was measuring a cooler or warmer mixture that it would adjust the fuel accordingly. The engine seems to be running VERY smoothly so I was pretty sure that if it was adjusting anything it would only be minimally.

Thanks
