o2 sensor warning light reset?

Post by dffrntwn »

I replaced the o2 sensor but the warning light remains on in the check panel. Is there a way to reset this in a 1984 633csi?

How much have you driven it since the replacement? Mine went out on it's own about 30 miles after the new one was installed.

I've driven the car hundreds of miles since the smog check and it's still on.

Then there probably is still a problem.

So it just goes off automatically, there's no reset? The former owner pulled the bulb before I bought the car, probably since they couldn't figure it out either. What other issue could cause it to stay on if the o2 sensor is new, and the car passed smog?
