Check engine light on but no codes!?!?
 

Has this happened to anyone? I'm worried

Full bright on, or just blink? What where you doing when it happened. Help us help you.

Just driving on the street 40mph cruising, its fully on. have uel headers and full exhaust and a tune.

What did you use to check for codes?

Im dealing with the same thing. Just switched to fa20club tune and about 100 miles into it, my CEL came on crusing down the freeway as well. I too have a catless header. What tune are you running?

visconti stage 2 1.14b4 pump gas 91 octane

When setting up custom maps in EcuTek there is an option to turn on the CEL when ever the custom map is active. It's useful when building the tune to make sure the custom map is working. It's possible the tuner left that on by accident. I did it to myself and freaked myself out.

I don't think that is the issue, I have been receiving a P219A CEL about every 200 miles (another issue we are trying to resolve) and that is what i thought this code would be however there is no code showing for this.

This just happened to me early morning. Car was at the train station for about 12h, cold start, about 65 deg, full tank of e85, cranked on fine on the right map, check engine came on after a mile... got home checked codes with ecu tek... no codes... cleared codes and started back up drove around 6h later... check engine light didnt come back... car drives fine no issues... only mods are vortech kit.
