Sorry for the long delay here. Was out of town. I think the following explains why some users are being told the purge valve is not a covered component under the federal emissions warranty. I do not think this is technically correct, and I believe this will explain it......
There are two categories under the federal emissions warranty:
1) Those components covered for 8 years or 80,000 miles. Only specific components are included in this category (shown below, underlined in red). Those components include the catalytic converter, electronic emissions control unit (ECM/ECU), and "onboard emissions diagnostic devices, including the Battery Energy Control Module (BECM)." This last category is most confusing and the best I can come up with is this refers to any device or module that makes official emissions-related diagnostic decisions (illuminating the check engine light). In researching what "onboard emissions diagnostic devices" means, it seems it consists of the PCM (already mentioned as ECU/ECM), diagnostic software and memory (which is part of the PCM/ECM/ECU), the MIL lamp, the OBD communication interface, and integrated monitoring functions for catalyst monitor, O2 sensors and heaters, EGR system, evaporative emission control system, fuel system and trim, misfire detection, secondary air system (if equipped), and electronic inputs/outputs to the PCM. The next logical question is, "what are integrated monitoring functions?" What I conclude here is that this describes the software functions that perform the monitoring of the emission components listed. Once again, these are likely just the software features that monitor the emissions systems described above for malfunctions, and as far as I can tell, this would just be one more way of saying the PCM/ECM/ECU or any other module that makes emission-related diagnostic decisions (referred to as DEC ECUs by CARB - Diagnostic or Emission Critical electronic powertrain control units).
2) All other covered components. In this category, the federal emissions warranty is surprisingly only 2 years/24,000 miles. As you can see below (circled in red), the factory Ford bumper to bumper warranty actually exceeds this at 3 years/36,000 miles and Ford even specifically calls this out. What I suspect (?) is happening is people are experiencing these purge valves failures outside the 3 year/36,000 bumper to bumper warranty and therefore, Ford is saying it's not covered. To say it's not covered because it's an "electronic or electrical component" seems completely incorrect. As mentioned previously, there are numerous electronic components listed on the "covered parts" list, so I don't think this explanation is technically correct, even if this is the reason cited by the dealer.
I think what is meant by the dealers when they say it's not covered is that the purge valve is failing outside the federally mandated 2 year/24,000 mile requirement, AND more importantly, outside of Ford's 3 year/36,000 bumper to bumper warranty, OR that it is not covered under the 8/80 federal warranty (which is correct) . Therefore, it's simply not covered because it's outside of the required (and optional) warranty coverage periods, not because it's "not a covered component" or because "it's an electronic/electrical component." Unfortunately, the end result is the same (no coverage!), but understanding the reason for the denial was important (at least it was to me).
If there are users that are experiencing purge valve failures prior to 3 years/36,000 miles and Ford is saying it's not covered (which seems completely contradictory because if that is not covered, what exactly does "bumper to bumper" mean?), I would be interested in hearing that story. The other category of customers that should have better protection are those in CA, as their emission warranty requirements are more strict than federal requirements.
I also think this means that claims that Ford modified the part number to include hoses as part of the purge valve assembly so the component would no longer be covered under warranty are also likely incorrect. I don't see anything in the requirements that would indicate that attached hoses or a change to the base part number would result in a change to the warranty requirements of a covered component.
NOTE: This is based on information from the 2022 Ford Warranty Guide. I realize there are users who have had their purge valves covered under warranty on other brands, models, or other model years. I suspect those may have been replaced within the 2/24 or 3/36 warranty periods, OR those manufacturers/dealers may have been operating under different (better!) interpretations of emission warranty requirements at that time.
