Will disconnecting battery reset a steady Check Engine light?

[2020-MAX-Limited]

Hosed off the Expy today at a carwash and steady Check Engine light was on after driving away. No noticeable engine symptoms, running normally. Considered the fuel door ('15 Expy with cap-less filler) might have broken seal, so I dried it off and made sure it sealed well when getting home. Understand the need for pulling codes to run it down, but was wondering if disconnecting the battery (neg terminal) will reset the light in an effort to repeat the fault before taking to a shop for codes. Am aware of earlier Fords working this way.

Sometimes, try it.

Not if it is a permanent code. Even some short term codes won’t be.

If it is EVAP related(Cap). Go for a few drives where you get over 45. It should clear itself...

I think some of the auto parts stores, Advanced and AutoZone will pull codes and reset for free.

Disconnecting the battery/ resetting with scanner will clear the light. However, if issue that set the code still exists the light will come back on. Usually takes 35-50mi for the vehicle to register issue exists; then the light will return.

Amazon sells a bluetooth OBD-II scanner for ~$10, and there's an app, Torque Lite (free) that allows you to reset it....

VERY handy to reset CEL lights for stupid reasons...
