Ok I went to emissions today and was told my 1998 Honda Civic EX was in " NOT READY MODE" because my battery had recently been disconnected,and was told by the personnel at the emissions sta. to drive it for awhile? My question is how long is awhile and does anyone know exactly how many miles this could be?? :confused:

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.
