To reset the check engine light on a Ford E450, first, use an OBD-II scanner to read and clear any diagnostic trouble codes (DTCs) that may have triggered the light. If you don't have a scanner, you can disconnect the negative battery terminal for about 15 minutes to reset the system. Reconnect the battery, and the light should turn off if the underlying issue has been resolved. However, it's advisable to address any underlying problems to prevent the light from reappearing.
