O2 SENSOR LOW POWER

2000 Chevrolet Truck • 196,000 miles

My check engine light came on so I hooked up my Snap-On scanner. I'm getting a code for O2 sensor low power. Can you tell me what that means and what I could do to fix that?

Your A/F mix is lean following will caused it

1. Vacuum leaks
2. EGR and PCV valve.
3. Low fuel pressure.
4. Dirty fuel injectors.
5. Mass Air Flow Sensor.
6. Oxygen Sensor.
