Pending codes? What codes are pending? Are you sure it just hasn't set readiness yet? Usually on obd2 scan tools or code readers, the top bubbles or ovals are the readiness states for the emissions control system. Ie. Cat, secondary air, evap, etc. If you haven't completed enough drive cycles, your monitors will not have had time to run all tests. One of these to make sure on would be to have between 1/4 tank and 3/4 tank of gas, otherwise the evaporative emissions test won't run.
