Mazda CX-5 Service & Repair Manual: Accelerator Pedal Position (App) Sensor Inspection
Voltage Inspection
NOTE:
-
Because the APP sensor is integrated in the accelerator pedal, replacing the APP sensor includes replacement of the accelerator pedal.
1. Connect the M-MDS to the DLC?2.
2. Switch the ignition ON (engine off or on).
3. Verify that the APP sensor output voltage (PID: APP1, APP2) increases according to the increase in the accelerator opening angle when the accelerator opening angle is gradually increased..
-
If verified, go to the next step.
-
If not as verified, replace the accelerator pedal..
4. Verify that the APP sensor output voltage (PID: APP1, APP2) is within the specification when the accelerator pedal is depressed and not depressed..
-
If not as specified, replace the accelerator pedal..

Magnet Clutch [Manual Air Conditioner]
Purpose
The magnetic clutch transmits the rotation force from the engine to the shaft
in the A/C compressor.
Function
The magnetic clutch engages or disengages the magnetic clutch and the A/C
turns on or off by switching the power transmission from the engine.

Air Fuel Ratio (A/F) Sensor Heater Control
Outline
Based on the control of the A/F sensor heater, a stabilized oxygen concentration
is detected even at low exhaust temperatures, and feedback control of fuel injection
even at cold engine start is made possible for improved cold temperature exhaust
emission performance.

Refrigerant Pressure Sensor Removal/Installation [Manual Air Conditioner]
1. Disconnect the negative battery cable..
2. Discharge the refrigerant..
3. Disconnect the refrigerant pressure sensor connector.
CAUTION:
If moisture or foreign material enters the refrigeration cycle, cooling ability
will be lowered and abnormal noise will occur. Always immediate ...
