Generac's Mobile Link card reads "A warning has occurred, ECODE 2202: Low fuel pressure," and its message list gives the warning as code 3217. Fuel pressure alerts show in Mobile Link only if the generator has a Power Zone 200 controller and is registered to a Mobile Link account.

Generac says an article for a code with the same first two digits generally applies to its variants, and that Evolution controllers show the code on an LCD while Power Zone 200 controllers show it only in Mobile Link.
