MAP SENSOR — FORD TAURUS / AEROSTAR / CROWN VICTORIA / MERCURY SABLE
New manifold absolute pressure sensor for Ford and Mercury passenger cars and minivans. Direct replacement for DY-520, DY520, DY-503, DY503, and Ford E6EF-9F479-A2A. This MAP sensor measures intake manifold vacuum and sends voltage data to the EEC-IV engine control module for optimal fuel injection and ignition timing. Fits Ford Taurus, Aerostar, Crown Victoria, LTD, LTD Crown Victoria, Thunderbird, Mercury Sable, Colony Park, Grand Marquis, and Cougar. Covers 3.0L V6 Vulcan, 3.8L V6, and 5.0L V8 engines across sedans, wagons, and minivans. A degraded MAP sensor leads to rough idle, poor fuel economy, engine hesitation, and check engine light activation. Manufactured to OE standards for accurate pressure readings and dependable long-term performance across all driving conditions.

Professional installation recommended. Verify OEM part number before ordering.
