A.I.R. Management Solenoid: Description and Operation

The ECM controls an AIR switch and solenoid, depending on CTS and TPS inputs, to allow air flow into either the exhaust manifold, catalytic converter,
or air cleaner.  Under certain conditions when the ECM recognizes a problem, the ECM will set the "SERVICE ENGINE SOON" or "SERVICE
VEHICLE SOON" message and disable the air management system.
