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.

Evaporative Emission (Evap) Control System
Purpose, Outline
Prevents release of evaporative gas into the atmosphere.
The intake manifold vacuum introduces evaporative gas to the intake manifold
via the charcoal canister and the purge solenoid valve.
