1997 Mercury Mountaineer AWD
1997 Mercury Mountaineer AWD born on 7/24/97 first year they were made. Manufacture date 7/97 Included an extra segment on why the Differential Pressure Feedback EGR (Exhaust Gas Recirculator) Sensor goes bad. I tried to show the white residue inside the vacuum lines which is corrosion caused by moisture. There is a TSB (Technical Service Bulletin) for Ford, Mercury and Lincoln SUVs for that sensor because it was originally manufactured with aluminum which corrodes in the presence of moisture and is a common cause for the check engine light of said vehicles to illuminate. The new sensors are now plastic and have the vacuum lines much further apart. On the 5.0 Liter engines, you will find this sensor next to the intake manifold and the transmission dipstick between the engine and firewall. Takes 5 minutes to change with right tools. The screw next to the transmission dipstick is the hardest to get to and will require an extension. I replaced the EGR(DPFE) sensor, that is why I am showing the old one in my video.
