You can try disconnecting the battery cable for 20 min. and see if that works, or take it to an independent garage and pay less than at the dealer.
Disconnect the battery for an hour or so or take the vehicle to autozone who diagnoses and resets computer free of charge.
Autozone allows, as a matter of policy, customers to use they're code scanner which has a reset/delete setting. With it, I reset an oxygen sensor and knock sensor error, they later came back on - so, I'll be replacing sensors soon - but it did allow me to reset the error codes generated by my car ('99 Maxima) and recorded on my car's computer. A few other parts stores will also do this - call around.
The connection is to the left of the steering wheel, bottom section of the dash board.
