Check engine light: air pump S70

When I cleared CEL this way it would never come back right away. I had O2 sensor going bad but the ECU would require three engine starts and 20 minutes of driving to show CEL, and my air pump would do the same. The only time the light would come instantly was when my distributor cap needed a replacement and ECU was giving me codes for rear knock sensor.
Hope it helps, good luck.
