About 10 days after Honda dealer replaced my spark plugs, I tried to get a smog check for registration renewal. I had drive more than 50 miles at varying speeds up to 65. I have had two smog checks rejected because some test parameters (OBD catalyst and OBD evap) show not completed.
What is required to complete a drive cycle so that a smog check can get info? on 2007 Honda Accord

it is a very specific way of driving to make the monitors run. you could drive 500 miles and never set a monitor. thats why it costs to have it done as we are familiar with driving the way it needs to be done. Roy
