Changed EGR Valve How Long for Check Engine light to Go Out? on 1998 Honda Odyssey

Will Engine Cleanes Help?

Asked by for the 1998 Honda Odyssey
The EGR valve failing is not as common a problem as the passage ways in the intake manifold getting restricted and clogged up with carbon. It's best to reset the check engine light with a scan tool but disconnecting the battery for a few minutes will erase all memory and turn off the Check Engine light, make sure you have radio security code prior to removing battery connection.
