Thought I would post this as I wasn't able to find the information posted anywhere and only alluded to.

You can reset your CEL codes with the stomp test -

After you enter the stomp test with 5 throttle presses per normal, and after the codes have been displayed, re-enter the 5-press stomp test. The CEL Should register and enter a single flash pattern. Now hold a single stomp down for 10 full seconds.

All CEL codes should now be cleared.
