    If you have cleared the computer then likely you are ready for inspection. Take the highway.

    I am guessing you are in a state that does the OBD-II emissions check, correct?

    If that is the case, from what I understand, all cars are different. They all have to go through a "readiness" cycle before the emissions can be checked and the time and conditions for this cycle vary on the car. I seem to see the common answer is 1 to 2 days of local and highway driving will usually get the computer back through the readiness cycle.

    With all the work trucks over the several states I have had to get inspected, the most common answer I have gotten from mechanics is 100 miles. Happy motoring.

    It really varies. It's all about the computer re-learning each of the different cycles, as 'odinn7' state. The fastest way to get there with the lowest miles is to hit the interstate and drive about 70 mph for 25 miles, take an exit and turn around and come back. I have the dreaded P0420 code right now myself and I'm waiting on new cats to arrive at the house. Good luck!

    After Clearing Codes, How Many Miles Do You Need To Drive Before You Can Have The Car Inspected?

    It's not an issue of miles--it's a function of drive cycles. Some drive cycles require a cold start, warm-up, and a certain number of miles at a certain speed. So, there's no set answer. It depends on the year, make, and model of the car, along with the specific trouble code.

    After a code is erased, the computer "monitors" conditions, until the drive cycle has been completed. Then, it "resets" the monitors, making it okay for inspection. There's no way to manually reset the monitors.

    If you have to clear the codes you have a problem. You can got to just about any auto parts store and they can check the code. It all depends on the code. If it is something simple you can disconnect the battery for about 10 min. but you should drive about 50 miles after that. They can tell if you clear or do something with the battery
