Hi there. There are probably more blown fuses than just the two you mentioned. That particular code generally means that the throttle motor circuit has no power available. I suggest checking all the fuses and replacing as necessary; this includes all in the engine compartment area and under the dash. If that checks ok I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a check engine light inspection.
