Dealer told me the light was on because the front 02 senser on the right side needed replaced. When I do this can I reset the system by disconnecting the battery for a few minutes?

Do you
have the same problem?

You can clear the codes that way but you will also clear all the adaptive memory functions including idle strategy and fuel adaptives. It will relearn them after a while but may not idle right when first started. Leave battery disconnected for at least 5 minutes.
