MAP Manifold Air Pressure Sensor 82001-21800 25085-00QAA 25085-00Q0B
-
Measures intake manifold pressure accurately: The MAP sensor converts real‑time intake manifold vacuum/pressure into a voltage signal, enabling 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 Nissan Micra and Altima.
-
Improves fuel efficiency: Precise manifold pressure data allows the ECU to deliver the correct air‑fuel ratio under all driving conditions, reducing unnecessary fuel enrichment and saving up to 10‑15% on fuel.
-
Reduces harmful emissions: Accurate pressure sensing helps minimise incomplete combustion, lowering CO, HC, and NOx emissions to help your Nissan pass emissions tests.
