MerCruiser® MAP & MAPT Sensors

Manifold Absolute Pressure (MAP) and combined Manifold Absolute Pressure and Temperature (MAPT) sensor replacements for MerCruiser® EFI and MPI engines.

MAP and MAPT are not interchangeable. MAP sensors measure manifold pressure only. MAPT sensors combine pressure and temperature sensing. The ECM-555 generation uses a MAPT sensor (885165 / 8M0087834) — do not substitute a MAP-only sensor.
