Q: Will I know if there is a problem with my vehicle's secondary air injection reaction (SAIR) system?
A: Yes, when the Secondary Air Injection System fails the 'check engine' light will appear. Black smoke coming from the exhaust can also be a sign of SAIR System failure.
Q: Are there steps I can take to ensure top secondary air injection reaction (SAIR) system performance?
A: Yes, it is important to maintain SAIR system components. Worn hoses are the most common cause of system failure. Carbon deposits resulting from inferior fuel are another cause of system failure.
