Manufacturers warn not to mistake an air / fuel ratio sensor for an oxygen sensor. Is the 2009 GLS Hyundai Accent fitted with air / fuel sensors? Would you know how many oxygen sensors come with this vehicle? What's the function of the air / fuel ratio sensor?
Will appreciate input concerning manufacturers that produce the best performing sensors.
Your help is requested. Thank you.
