2001 Mercury Sable with Duratec V6 DOHC engine: EGR Vacuum Solenoid question
The car was in a bad shop out of town and came out with a fresh set of problems. It is
now generating a P0401 Engine Check Code which indicates there is a problem with the
EGR system. Looking things over I noticed that there are no vacuum tubes on the EGR
Vacuum Solenoid. That seems like a likely excuse for the engine check. Where do those
small tubes come from and go to?
