Check Engine light question
How do you know it is working or not?....does it normally come on with the first key position and then go off?....have yet to see mine...the bulb is in place, have not tested the bulb however. I see there is a maintenance required position as well in the panel without a bulb behind it. Trying to get all the stuff from the PO straight.

Turn it from off position to on position 3 times then leave it in on position and it should flash a code

The light should come on when you first start up and then go off after a few seconds

I just got my TJ inspected and my bulb was blown which failed my inspection. Mechanic was able to remove dash and replace bulb on mine. Every time I start it up it shows for a couple of seconds now.

The Maintenance Required light was an emissions timer to remind folks to replace the O2 sensor at 82500K and it just needs to stay removed as useless as the shift light.
