Product Details

The Regitar USA RMJ002 is a direct replacement Manifold Absolute Pressure (MAP) sensor designed specifically for MerCruiser marine engines equipped with Electronic Control Module (ECM) 555. This precision sensor monitors intake manifold pressure and provides critical data to the engine control unit for optimal fuel delivery and ignition timing.

Key Features:

  • Direct fit replacement for MerCruiser V-6 and V-8 multi-port injection (MPI) engines
  • Compatible with 305, 350, and 496 cubic inch displacement engines
  • Designed for use with ECM 555 engine control systems
  • Helps maintain proper air-fuel mixture and engine performance
  • OE-quality construction for reliable marine environment operation

This MAP sensor is essential for proper engine management, helping to ensure smooth operation, optimal fuel efficiency, and responsive throttle performance. A failing MAP sensor can cause poor acceleration, rough idling, and decreased fuel economy, making timely replacement critical for maintaining your MerCruiser engine's performance.
