Well let me see if I can say this without putting my foot in my mouth.
The map sensor is the one with the three vacuum hoses that go to the throttle bodies the sensor in the air box where the are original air filter sets is the (ats) air temperature sensor it measures the air temp going into the throttle bodies and the ecu uses that info when setting fuel ratio.
if this sensor gets to close to a real hot surface it will through off the fuel ratio.
Air pressure, not temp. (Tho pressure will vary with temp.) The Intake Air Temp. Sensor in the intake plumbing does the temp.
