Mazda 2: Fuel-filler Cap
FUEL-FILLER CAP INSPECTION
Leakage Inspection
1. Perform the following SST (Evaporative Emission System Tester 134-01049A)
self-test:
NOTE:
- If the tester does not work correctly during self-test, refer to the
tester
operators manual for more detailed procedures.
- Verify that the gas cylinder valve is closed and the control valve
located on the
tester is in the TEST position. All tester displays should be off at this
time.
- Connect the long hose (part of SST) to the tester.

- Connect the manifold assembly (part of SST) to the long hose as shown.
- Open the gas cylinder valve and verify the gas cylinder regulator left
gauge
reads 69-82 kPa {0.71-0.83 kgf/cm2, 10-12 psi} (preset at factory).
- If not, refer to the tester operators manual to contact tester
manufacturer.
- Press the ON/OFF switch to turn on the SST and make sure the left
display
reads 0.0.
- Turn the control valve on the tester to the FILL position.
- Verify the left display reading is within 13.9 to 14.0 in of water.
- If not, adjust the pressure using the regulator knob located on
the right side of the tester.
- Turn the control valve to TEST position and press the START switch.
- After the 2-min countdown (left display) is completed, the right display
shows
the total pressure loss for that period. A 0.5 in of water loss is
acceptable on the
self-test.
2. Press the RESET switch to set the left display reading to 0.0.
3. Connect the fuel cap receiver assembly (part of SST) to the manifold assembly
and fuel-filler
cap from the vehicle.
- If the fuel-filler cap is not a genuine part, replace it.

4. Turn the control valve to the FILL position.
5. Wait (maximum 20 s) until the left display reads 13.9 to 14.0 in of water.
- If the reading is slightly below the specification, adjust it using the
regulator
knob.
- If the reading is far below, the fuel-filler cap has leak. Replace it.
6. Turn the control valve to the TEST position and press the START switch.
7. After the 2-min countdown (left display) is completed, check the test result
(the
failed/passed light on the tester).
- If the green light turns on, the fuel-filler cap is normal.
- If the red light turns on, the fuel-filler cap has leakage. Replace it.
8. Close the gas cylinder valve.
9. Turn the control valve to the FILL position.
10. Press the ON/OFF switch to turn off the tester.
AIR FILTER INSPECTION
Airflow Inspection
1. Remove the air filter. (See AIR FILTER REMOVAL/INSTALLATION).
2. Blow from port A and verify that there is airflow from port B.

- If there is no airflow, replace the air filter. (See AIR FILTER
REMOVAL/INSTALLATION).
3. Blow from port B and verify that there is airflow from port A.
- If there is no airflow, replace the air filter. (See AIR FILTER
REMOVAL/INSTALLATION).
