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.
Intake Air Temperature (Iat) Sensor Inspection
IAT Sensor No.1
Resistance inspection
NOTE:
Because the IAT sensor No.1 is integrated in the MAF sensor, replacing the
IAT sensor No.1 includes replacement of the MAF sensor/IAT sensor No ...
Intake Manifold Vacuum Inspection
1. Disconnect the evaporative hose No.3 (purge solenoid valve side) and install
the vacuum gauge..
2. Verify that the intake air hoses are installed securely.
3. Warm up the engine.
4. Measure ...

Parking Mechanism [Fw6 A EL, Fw6 Ax EL]
Purpose/Function
The parking mechanism locks the output gear when the selector lever is shifted
to the P position which locks the driving wheels against rotation to prevent
coasting when parking the vehicle.
