How long is a "driving cycle"?

Start it up, warm it up to operating temperature, turn it off, let it cool down. That's a "driving cycle"


I did actually use the car with the new sensor plugged in and just hanging by its wire for a couple hours. Think its heating unit could have burned out?

Not real likely that the heater would have burned out since the thing normally operates in the environment of the inside of the exhaust pipe, but it might have damaged the connector or wiring while dangling like that. O2 sensors operate in a very narrow voltage range and are very sensitive to damaged wiring.



If clearing the code doesn't work, then you might try a different brand sensor. In the meantime, take a careful look at the wiring and connector.

Reset codes. Have done 3 driving cycles, engine light still off. So I think the repair fixed my issue.

Thanks to all who helped. love the forum.
