• How To Pass Inspection & Complete A Drive Cycle

    Please correct me if I am wrong, but the purpose of completing the drive cycle is to give the computer ample time (mileage) to compile the adequate sensor data needed to identify any out of range values. The module is "ready" when enough data has been collected and if the problem has not been corrected at this point it will simply trigger another code and tbe CE light will already be back on. In your case, it's a couple of months before the code is thrown, (emission faults usually take longer to show up) but experience varies greatly between different makes and models... and age is definately a factor. You were probably able to make it back to the inspection station before the light came back on because the technology in your car is over 12 years old. Late models are not near so forgiving and most likely this method will be of little to no use.
