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.

This system uses the key buttons to remotely lock and unlock the doors and the
liftgate.
The system can start the engine without having to take the key out of your purse
or pocket.
It can also help you signal for attention.

Barometric Pressure (Baro) Sensor Inspection
Voltage Inspection
NOTE:
Because the BARO sensor is integrated in the PCM, replacing the BARO sensor
includes replacement of the PCM.
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the BARO sensor output voltage (PID: BARO) is wi ...

WARNING:
Handling a side air bag improperly can accidentally operate (deploy) the
air bag, which may seriously injure you. Read the service warnings/cautions
in the Workshop Manual before handling the front seat (side air bag integrated)..
CAUTION:
