This GSB came out in 2018 and is applicable to all Ford products.
Reference this GSB if it is found that a vehicle has the following DTCs:
P0071
P0072
P0073
Also per the GSB:
There may be a customer concern with an illuminated MIL or Check Engine lamp. These lights may or may not be associated with the P0071, P0072 or P0073 DTCs. In some cases these may be the result of moisture / corrosion at the AAT connector. When directed by the WSM or PC/ED, the AAT and other associated connectors integrity should be verified.
