Intake Air Temperature (IAT) sensor is a thermistor built into MAF meter and is used to monitor temperature of air flowing through MAF meter.

Thanks much folks, Almost there. There are two sensors there, a large one (A) on top on the ait intake, then a small one (B) "inline" with the intake going to some kind of air hose. (See the pic) Which one is it please?
