The EGT sensors are not related to the DEF problem you. EGT sensors haven't be a problem as they once did after Ford updated the calibration of the ECU/PCM a few years ago. Ford, also extended the warranty on the EGT sensors but your truck being a 2012, it might be past the warranty extension.
DEF is injected into the exhaust after the CAT and DPF. Have you check the DEF level? Have you pulled any OBDII codes that might identify the problem?
