Mazda CX-5 Service & Repair Manual: 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.1.
1. Disconnect the negative battery cable..
2. Disconnect the MAF sensor/IAT sensor No.1 connector.
3. Measure the resistance between MAF sensor/IAT sensor No.1 terminals A and B.
-
If not as specified, replace the MAF sensor/IAT sensor No.1..

IAT Sensor No.2
Resistance inspection
NOTE:
-
Because the IAT sensor No.2 is integrated in the MAP sensor, replacing the IAT sensor No.2 includes replacement of the MAP sensor/IAT sensor No.2.
1. Disconnect the negative battery cable..
2. Disconnect the MAP sensor/IAT sensor No.2 connector.
3. Remove the MAP sensor/IAT sensor No.2..
4. Measure the resistance between MAP sensor/IAT sensor No.2 terminals A and B.
-
If not as specified, replace the MAP sensor/IAT sensor No.2..

Shift Pressure Control (Line Pressure Control) [Fw6 A EL, Fw6 Ax EL]
Outline
The TCM drives the pressure control solenoid and adjusts the pressure based
on the accelerator pedal depression amount, vehicle speed, ATF temperature,
and gear shift signal. As a result, line pressure is controlled finely and with
high accuracy according to the engine load c ...

When Warning/Indicator Lights Illuminate/Flash
If the brake system warning light illuminates
If the light stays on after the parking brake is fully released there may be
a problem with the brakes.
