Air Intake Actuator Inspection
WARNING: This page is about a different car, the 2018 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
- If the lever position exceeds the operation range shown in the figure below, the circuit in the actuator could be damaged. Always perform an actuator operation inspection with the lever movement within the range shown in the figure below.
- Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION .)
- Remove the following parts:
- Passenger-side front scuff plate (See FRONT SCUFF PLATE REMOVAL/INSTALLATION .)
- Passenger-side front side trim (See FRONT SIDE TRIM REMOVAL/INSTALLATION .)
- Glove compartment (See GLOVE COMPARTMENT REMOVAL/INSTALLATION .)
- Dashboard under cover (See DASHBOARD UNDER COVER REMOVAL/INSTALLATION .)
- Passenger-side decoration panel (See DECORATION PANEL REMOVAL/INSTALLATION .)
- Passenger-side lower panel (See LOWER PANEL REMOVAL/INSTALLATION .)
- Passenger-side front heat duct (See FRONT HEAT DUCT REMOVAL/INSTALLATION .)
- Blower unit (See BLOWER UNIT REMOVAL/INSTALLATION .)
- Remove the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION .)
- Apply battery positive voltage and connect the ground to the air intake actuator terminals as indicated in the table below and verify the operation condition.
B+ Terminal Ground Terminal Operation B A FRESH → RECIRCULATE A B RECIRCULATE → FRESH - If not as indicated in the table, replace the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION .)
- Verify that the resistance between terminals C and D, D and E matches the air intake actuator operation as shown in the graph.
- If the operation condition and resistance are not normal, replace the air intake actuator. (See AIR INTAKE ACTUATOR REMOVAL/INSTALLATION .)
