2002 Acura TL How to Clear a Check Engine Light

Your 2002 Acura TL will display a "check-engine" light when there is a problem with the various sensors.

The trouble codes can be read by a diagnostic scan tool, but when you're done getting the information you need, you need to clear the codes on your TL or the check-engine light will stay lit.
