    Q:
    What Are the Diagnostic and Replacement Procedures for Check Valve? Posted by Customer
    A:
    This AIR system was designed to reduce hydrocarbon and carbon monoxide levels in the exhaust by injecting air into the exhaust ports or catalytic converter. The system uses an air pump, air management valve, and check valves that direct air to the correct location based on engine temperature and driving conditions. To diagnose any issues one should check hoses, vacuum lines, wires for damage, and ensure pump drivebelt is in good condition. Pump can be checked by feeling its pulsations and noting parallel airflow with increased engine speed. The check valve should only allow air flow in the direction of normal air flow. The vacuum presence can be checked in the air management valve while deceleration valve for air flow and engine speed drop. Note the routing of hoses and tubes, tighten all connections before replacing any components. Disconnect outlet hose and remove valve from pipe assembly to replace check valve. Disconnect vacuum signal line, air hoses, electrical connectors then remove mounting bolts inorder to change air management valve. Remove the adapter together with the drive belt then unbolt the mounting bolts before installing a new pump (remove the old one). Disconnect vacuum hoses, remove retaining screws then install new deceleration valves.
