CO2 Sensor cleaning

Is it possible to clean the CO2 sensors? And if how?

Um CO2? No such animal on your van, or any other vehicle that I know of. Do you mean the O2 (oxygen sensor)? If so, nope, replacement is the ONLY option.

Yep, I mean the O2. Thanx for info.

It may be a tall tell. But I heard soaking them in pepsi or coke for a 1 to 2 hours has helped. Might try it my self one day..
