Mazda CX-5 Service & Repair Manual: Intake Air Temperature (Iat) Sensor
IAT Sensor No.1
Purpose/Function
-
Detects the IAT before it passes through the throttle body as basic information for mainly determining the fuel injection amount.
-
Detects the IAT before it passes through the throttle body and inputs it to the PCM as an IAT signal.
Construction
-
Built into the MAF sensor.
-
A cold resistor has been adopted as the detecting element for detecting the IAT.
Operation
-
Inputs the signal, which fluctuates according to the IAT after passing through the air cleaner, to the PCM.

IAT Sensor No.2
Purpose/Function
-
Detects the IAT (in intake manifold) after it passes through the throttle body as basic information for mainly determining the fuel injection amount.
-
Detects the IAT (in intake manifold) after it passes through the throttle body and inputs it to the PCM as an intake air temperature signal.
Construction
-
Built into the MAP sensor.
-
A cold resistor has been adopted as the detecting element for detecting the IAT.
Operation
-
Inputs the signal, which fluctuates according to the IAT in the intake manifold, to the PCM.
IAT sensor No.2 characteristic
Fail-safe
-
Function not equipped.
