4327233 3078155 Double Plug Engine Speed Sensor Replacement for Cummins NT855 M11 QSM11 6BT Hyundai Excavator R455-7 2872353

Product Overview The 4327233 / 3078155 Double Plug Engine Speed Sensor is a premium heavy-duty diagnostic component engineered for Cummins Diesel Engines and Commercial Construction Machinery. Featuring a specialized dual-connector (double plug) interface, this high-precision sensor is designed to accurately monitor crankshaft rotational speed (RPM) and gear timing, feeding vital synchronization telemetry directly to the Engine Control Module (ECM). By maintaining a crystal-clear, steady signal feed, it ensures optimal fuel injection timing, prevents erratic governor operation, and eliminates dashboard gauge fluctuations, making it an essential replacement part for high-hour commercial fleets, generator sets, and earthmoving excavators. Technical Specifications Main OE Numbers: 4327233, 3078155 Interchangeable Numbers: 2872353, 3073899, 3616371 Plug Configuration: Heavy-Duty Double Plug (Dual Connector) Waterproof Interface Function: Diesel Engine RPM, Flywheel Speed, and Rotational Timing Monitoring Material: High-Grade Anti-Magnetic Metal Alloys and Thermal-Resistant Engineered Composites Condition: 100% Brand New Premium Aftermarket Replacement Broad Vehicle Compatibility This universal double-plug speed sensor features an incredibly extensive application profile, crossing over multiple industry-standard Cummins engines and heavy equipment platforms: Series Compatible Models & Engine Applications Cummins Heavy-Duty Mechanical NT855, NTA855, G855, M11, ISM11, QSM11 Series Engines Cummins Medium-Duty & Industrial 4B3.9, 4BT, 6B5.9, 6BT, 6C8.3, 6CT, QSL9 Engines Hyundai Robex Excavators Robex R455-7, R455LC-7 Heavy Excavators (Powered by Cummins engines) Power Generation & Mining Compatible with various heavy-duty diesel gensets, marine power units, and large mining dump trucks requiring 4327233 specs Key Benefits Specialized Double-Plug Design: Perfectly matches factory configurations that utilize dual wiring leads for simultaneous ECM data routing and auxiliary gauge display monitoring. High Thermal & Vibration Resistance: Built with premium materials to survive prolonged exposure to blistering engine block environments, thick grime, and severe heavy equipment shocks. Precision RPM Calibration: Effectively eliminates active sensor diagnostic codes, engine sputtering due to timing drops, and false overspeed shutdowns in generator applications. Easy Installation: Drop-in dimensional fitment ensures zero hassle during screw-in mounting, maintaining the exact factory gap clearance with the timing gear. Cross-Reference Guide This sensor interchanges with the following original and aftermarket part numbers: CUMMINS / PACCAR: 4327233, 3078155, 2872353, 3073899, 3616371 HYUNDAI MACHINERY: Direct replacement for original factory speed inductors found on listed -7 series crawler chassis Maintenance Tip: If your Cummins NT855 generator or Hyundai R455-7 Excavator experiences sudden engine hunting, hard hot-starting, or an active RPM communication fault code, inspect the 4327233 sensor connections. Due to its dual-plug layout, make sure both harnesses are clipped tightly and free of oil mist. We recommend wiping the magnetic sensor head completely clean of any micro-metallic filings during installation to ensure optimal inductive signal clarity.
