I'm trying to help my daughter and son in law figure out this DTC. P0221 Throttle/Pedal Position Switch B Circuit Range/Performance. I never had this issues when I had the Ex this started a few months ago. They have tried 2 Pedal position sensors from Dorman and the issue keeps coming back. I cleaned all the connectors with elec Parts cleaner. Ford doesnt sell the sensor by itself you have to buy the entire pedal. other than replacing the entire pedal assembly what do you guys suggest?
Thanks guys! We removed the pedal from the truck cleaned and lubed the IVS and the entire pedal assembly. Reinstalled the pedal and will see if the problem persists.
