Looking to reset the "check engine" light on a 2005 odyssey
You need to be concerned with what caused the Check Engine Light to come on, and later turning it off. The OBDII system has detected a fault somewhere. It can be turned off with a scanner, but will just reappear until the fault id found and fixed. For starters, the most common cause is a loose or missing gas cap. If that does not do it, you need an OBDII scan.
if problem is fixed and does not clear code try disconnecting both battery terminals and holding wires together for 20 seconds usually resets computer
