CEL after 6 years

[derfo]

Hello everybody

I just thought I would post how things are going. I replaced the 02 sensor on the drivers side. In the manual for the Autel tool it says you can delete the codes, which then I assume the CE light goes off. That is what I was going to do when I got home from work. On the way home however the CE light went out itself. I suppose this tells me that the new sensor works and is communicating the right info to the DME.
My question would be then, does this happen to all repairs of sensors, is it best to wait for the light go out itself after the repair or replacement. Or doesn't it matter.
This is all very basic stuff I suppose to all those of you who have been using diagnostic tools for years, but to newbies like me, its a big learning curve.

Works with some MIL lights, but not all. Some have to be manually reset.

Thanks JFP, I will bear that in mind. Is MIL an American abbreviation?

MIL stands for "Malfunction Indicator Light", and is a widely used term in automive circles. While most are used to CEL for "Check engine light", it only refers to one light. MIL applies to all of the "idiot lights" on the dash(CEL, airbags, seatbelt, your car payment is due, etc).

Thanks again JFP, all this will add to my knowledge and understanding of this area of fault finding.
