I'm doing a project for school and im basically making a OBD scanner more or less. However, i want to intentionally throw a code and make the "service engine soon" light come on and my question is how i can do this and what is the best way? for example if i unplug an o2 sensor and drive a couple miles will this do it? or should i unplug the MAF? or something like that. I know this is an odd question but thanks guys!

P.S. my goal is to throw a code the fastest and least damaging way to my car haha

unplug maf, it will immediately trip the ses light. No damage to the engine

You could also pull a plug wire loose... Wont damage anything unless you drive it like that for a long time.

Unplugging Maf would be my choice.

unplugging any sensor should do it really
would be interested in your scanner if you have details

thanks everyone!

we are basically making an android app that communicates with a Bluetooth OBD2 reader which will display codes and real time data

Unplug the IAT connector with KOEO (key on, engine off).
