How do you reset a check engine light for a f150 5.4?

To reset the check engine light on a Ford F-150 with a 5.4L engine, you can disconnect the negative battery terminal for about 15 minutes to clear the codes. Alternatively, you can use an OBD-II scanner to erase the trouble codes directly. If the issue that triggered the light is not resolved, the light may come back on after resetting. Always ensure to diagnose and fix any underlying problems before resetting the light.
