MAP Pressure Sensor 1S7A-9F479-AC 1S7Z9F479AA
-
Measures intake manifold pressure accurately: The MAP sensor converts real‑time intake vacuum/pressure into a voltage signal, allowing the ECU to calculate air density and adjust fuel injection for optimal combustion.
-
Restores engine performance and drivability: A failing sensor causes hesitation, surging, or stalling. Our sensor provides fast, linear pressure readings, restoring smooth acceleration and stable idle on Ford, Lincoln, and Mercury vehicles.
-
Improves fuel efficiency: Precise manifold pressure data enables the ECU to deliver the correct air‑fuel ratio under all driving conditions, reducing unnecessary fuel enrichment and saving fuel.
-
Reduces harmful emissions: Accurate pressure sensing minimises incomplete combustion, lowering CO, HC, and NOx emissions to help your vehicle pass emissions tests.

Why Choose Our MAP Pressure Sensor 1S7A-9F479-AC 1S7Z9F479AA
Perfect Fit, Easy Installation
Made to factory specifications for a hassle‑free installation. Designed as a direct replacement for your original MAP sensor, it fits perfectly without any modifications.
OE Specification Manufacturing
All parameters follow original equipment standards, ensuring identical performance and reliability to the OEM part. You get the same quality at a fraction of the cost.
Direct Plug‑and‑Play Replacement
No wiring, splicing, or bracket changes are required. Installs in minutes with basic hand tools, saving time and labour costs.
Improved Fuel Economy
By providing precise intake manifold pressure data, the sensor helps the ECU optimise injection quantity and ignition timing. This reduces unnecessary fuel consumption and saves money at the pump.
Enhanced Power Performance
Fast and accurate pressure readings allow the engine to deliver maximum power during acceleration and maintain smooth operation at cruise. You will feel sharper throttle response and better drivability.
Reduced Environmental Pollution
Accurate sensing enables near‑stoichiometric combustion, which lowers harmful emissions (CO, HC, NOx). This helps your Ford, Lincoln, or Mercury pass strict emission tests and reduces your environmental footprint.
