Failed functionality test (no data from 02 sensor, 02 heater, and evaporation system). After the oil changed odometer was reset and added approximately 239 miles to gain data after being zero out.

I dont understand how the monitors can be good with a issue with o2 sensor heater and evap.So there is no data stream from the o2 sensor?
