Hi,
the o2 sensor does not work well with my bike, when the bike is idling the sensor gives me a value of approximately 0.8V, from 2000 rpm up the o2 sensor is at 0v. I bought other o2 sensor from a junkyard but gives me the same problem. the measurement is precise (with oscilloscope)

but the sensor error appears in the instrument cluster? even if I go around with the sensor error does not come out
