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.

WARNING:
Never remove the cooling system cap or loosen the radiator drain plug while
the engine is running, or when the engine and radiator are hot. Scalding engine
coolant and steam may shoot out and cause serious injury. It may also damage
the engine and cooling system.

Engine Tune-up Preparation
NOTE:
If the accelerator pedal is depressed continuously for a specified time,
the engine speed may decrease to the idle speed. This is due to the fuel cut
control operation, which prevents overheating, and it does not indicate a malfunction.
