Intake Air Temperature (IAT) Sensor 1-2 Correlation

Possible Causes:



When the engine is cold, at ignition ON, a properly functioning IAT sensor will gradually increase the scan tool IAT Sensor parameter. This is due to the heat that is generated by the MAF sensor heating elements.
 
Depending on the ambient temperature, an IAT sensor signal circuit that is shorted to the MAF sensor signal circuit can cause either a rapid fluctuation in the IAT Sensor parameter or cause it to become stuck at a given value.
 
An IAT low reference circuit that is open can cause the IAT Sensor parameter response to be sluggish.
 
An IAT sensor 2 signal circuit that is shorted to the boost pressure sensor signal circuit can cause the IAT Sensor 2 parameter response to be sluggish or become stuck at a given value.
