More about this item

Mercury Marine 864856A1 Sensors

The Mercury Marine MAP (Manifold Absolute Pressure) Sensor #864856A1 is a genuine OEM replacement component engineered to maintain peak engine performance in Mercury outboard and sterndrive applications. This precision sensor continuously monitors intake manifold pressure and relays critical data to the engine control module (ECM), enabling accurate fuel delivery and optimal ignition timing for maximum power and fuel efficiency.

Using an authentic Mercury Marine part ensures exact fit and function with no guesswork or compatibility concerns. The #864856A1 is manufactured to the same exacting tolerances as the original factory sensor, delivering reliable signal accuracy that aftermarket alternatives simply can't match. A faulty or degraded MAP sensor can cause rough idling, poor throttle response, increased fuel consumption, and hard starting — replacing it with this genuine part restores your engine to factory specifications quickly and confidently.

Lightweight at under a quarter pound, this sensor installs easily and is designed for long-term durability in the demanding marine environment. Whether you're performing routine maintenance or diagnosing a performance issue, the Mercury Marine 864856A1 MAP Sensor is the correct, reliable choice to keep your engine running at its best on the water.
