    Hi abovpar,

    All of the sources I've researched indicate that a 2000 Saturn L-series with the 2.2L engine doesn't have an air injection system. It was present on 2001-2003 4-cylinder models. Additionally, there is no "sensor" in the system. There's a control solenoid valve, a check valve, a control valve, a hose, a pump, and a relay, but no sensor.

    However, the system is covered in Haynes manual no. 87020, Chapter 6.
