2000 Mercury Grand Marquis 4.6L Emission Label (VECI) - Vacuum Hose Routing

This is a photograph of the underhood Vehicle Emission Control Information (VECI) label issued by Ford Motor Company, affixed to the vehicle. The label states the vehicle is equipped with electronic engine control systems and that engine idle speed, idle mixture, and ignition timing are not adjustable, directing the reader to the Powertrain Control/Emissions Diagnosis Manual for more information. It specifies the use of SAE 5W-30 American Petroleum Institute certified oils for gasoline engines. The label certifies that the vehicle conforms to U.S. EPA regulations applicable to gasoline-fueled 2000 model year new motor vehicles. A vacuum hose routing diagram is printed on the right side of the label, though most of its component callouts are too worn or small to read in this photo; a 'FRONT OF VEHICLE' orientation note is visible. Key tune-up data includes a spark plug gap of .052–.056 inch, the engine family designation 4.6 L-YFMXR0115BAE, and emission system code YFMXV04.6VB5-2TWC(2)+2HD2S(2)/EGR/SFI, indicating a 4.6-liter engine with dual three-way catalysts, heated oxygen sensors, EGR, and sequential fuel injection. The label part number YW7E-9C485-GGL and the word 'Catalyst' appear at the bottom, with barcode calibration code 46VEGXBG along the right edge.
