Sensors

What sensors affect A/F ratio?

02's, Maf, and PIP. I know Im missing some.

BAP, TPS, IAT, and ECT are a few more.

Is that all of them?

can't forget ACT

can't forget ACT

IAT and ACT are both inlet air-temp sensors.

So IAT and the ACT are the same thing?

 

[HISSIN50]

IAT (Intake Air Temp) and ACT (Air Charge Temp) sensors are the same.

Generally the fox III's call it an ACT and it's in the lower intake. SN95's call it a IAT and it's in the air inlet tube. The sensor does the same thing for both however, simply relating intake air temps.

And in my first post, along with those already noted, are the biggies I can think of. Arguably things like the EGR position sensor would play a role if the car has an EGR.
