This system utilizes exhaust pressure pulsation to draw clean air from the inside of the air cleaner, into the exhaust system. The system's function is to reduce hydrocarbon (HC) emissions.

The only service possible is replacement of the aspirator or check valve. See the air injection check valve procedures in this section.
