 9.CHECK AIR CUT SOLENOID VALVE
 10.REPLACE COMPONENTS
Replace secondary air injection system mass air flow sensor and air pump cleaner filter. ■ CAUTION ■ - Always replace the parts, because the secondary air injection system mass air flow sensor and air pump cleaner filter become dirty due to the blow back of the exhaust gas.
- Never clean up the secondary air injection system mass air flow sensor and air pump cleaner filter.
>>GO TO 11.
 11.CHECK COMPONENTS
Check the following. Is the inspection result normal? YES >>INSPECTION END NO >>Repair or replace malfunctioning part.
 12.CHECK INTERMITTENT INCIDENT
