For those of you who have a scanner that can reset the CEL I have found that Leaving the Plastic OBD cover off helps prevent CELs.

If I put the cover on, I get a CEL within 200 miles, with the plastic cover removed: nothing . . .

Also carrying the scanner in the car prevents the light from coming on. Leave the scanner in the garage and you increase the likelihood of a CEL tenfold, even more if it is a long trip.

 

I have also found that pulling the gauge out and removing the CEL bulb REALLY reduces the incidents of CELs illuminating.

 

LOL that is funny!

What cel are you getting?

 

Andy,
Nicely done. Sounds like you have come up with some very scientific solutions. Like Bob I have taken a slightly different approach and have had 100% success with removing the bulb. And I didn't even have to pony up for a scanner!

 

It also helps if you call your shop everyday and make an appointment to check a CEL. The CEL light disappears immediately the next morning right before taking the car in.

I just call the shop everyday and make an appointment for the next morning. Not a single CEL in 3 years!

 

Brilliant!
