21160659 Crankshaft Position Sensor Replacement for Volvo Truck FH FM FMX D11 D13 Engine Excavator EC360 EC460 20513340 5MT2033-01 505-5511

Product Overview The 21160659 / 20513340 Crankshaft Position Sensor is a premium commercial-grade heavy-duty vehicle diagnostic component engineered explicitly as a high-reliability replacement for Volvo Commercial Trucks, Highway Logistics Fleets, and Volvo Heavy Construction Machinery. Threaded securely adjacent to the primary engine flywheel housing or front crankshaft timing gear array, this high-precision electromagnetic induction tracking sensor reads the rotational speed and precise top dead center (TDC) position of the engine crankshaft pistons. By transmitting instant, zero-lag electronic pulse square-wave telemetry straight to the main Engine Control Unit (ECU), it secures flawless fuel injection synchronization, perfect cylinders firing timing, and stabilizes fuel efficiency under punishing heavy-haul hauling and extreme quarry excavation site loads. Technical Specifications Primary Volvo Factory Genuine OE Reference: 21160659, 20513340 Historical Legacy Interchange Code: 8078108 Commercial Logistics Trading Identifications: 5MT2033-01, 505-5511, 02184 Sensor Modality: High-Sensitivity Inductive Electromagnetic Proximity Pickup / Position Sensor GP Primary Function: Engine RPM Calculations, Crankshaft Position Synchronization, and Cylinder Fire Synchronization Terminal Configuration: OEM-Matched Heavy Duty Sealed Waterproof and Dustproof Connector Plug Lock with Insulated Harness Leads Condition: 100% Brand New Premium Commercial Powertrain Aftermarket Replacement Broad Vehicle & Equipment Compatibility This heavy-duty position velocity sender delivers exact original factory dimensional matching and signaling compliance across Volvo’s legendary D-Series engines driving global logistics and heavy earthmoving sectors: Equipment Family Compatible Volvo Engine Models & Heavy Machinery Applications Volvo Heavy Commercial Trucks Volvo FH, FH12, FH16, FM, FM12, FMX Logistics and Dump Trucks powered by D9, D11, D12, D13, and D16 heavy-duty diesel motors Volvo Track Hydraulic Excavators EC330, EC340, EC360, EC380, EC460, EC480 heavy mining and digging platforms utilizing matched electronic injection layouts Volvo Articulated Dumpers & Wheel Loaders A35, A40 Articulated Haulers and L150, L180, L220, L250 Wheel Shovels tracking real-time engine rev telemetry Volvo Penta Industrial Powers Select marine auxiliaries and prime stationary generator stations utilizing co-engineered automated speed controls Key Benefits Immediate ECU Synchronization: Calibrated strictly to native Volvo engine resistance and wave amplitude specifications, allowing immediate active fault code clearing (e.g., active check engine or limp-mode codes) without expensive dealership software reflashing. Severe Heat & Vibration Protection: Fully encapsulated solid-state structural housing easily handles extreme engine block thermal spikes, hot engine oil splash soaking, carbon soot contamination, and violent engine block vibrations. Critical Engine Cranking Errors Solved: Swiftly addresses severe powertrain malfunctions such as hard starting when engine is hot, sudden engine stalling under heavy load, erratic idling, or massive fuel economy drops caused by intermittent timing signals. Drop-In Leak-Free Installation: Fabricated to exact original physical factory blueprints to guarantee a tight, fluid-proof physical thread-in lock that completely stops oil weeping around the timing casing block. Cross-Reference Guide This industrial closed-loop agricultural electrical sensor interchanges directly with the following international manufacturer catalogs: VOLVO GROUP (GENUINE): 21160659, 20513340, 8078108 GLOBAL SPARES SYSTEMS: 5MT2033-01, 505-5511, 02184 Industry Indexing Mapping COMMERCIAL FLEET ENGINE PARTS: Premium high-durability replacement automation electronics calibrated to match original factory diagnostic signaling profiles Maintenance Tip: If your Volvo FH12 Truck or EC460 Excavator with D13 Engine struggles to crank up smoothly during morning ignition, cuts power abruptly when entering a heavy digging cycle, or triggers active dashboard warnings for crankshaft signal failure, evaluate the 21160659 position sensor plug immediately. Because this component operates directly adjacent to fast-spinning flywheel gear teeth or timing wheels, its magnetic inductive tip naturally collects a heavy slurry of microscopic metal engine wear dust mixed with carbonized oil residues over thousands of severe operational hours. This layer heavily dampens the digital signal pulse loops. Before plugging in this new replacement unit, always wipe the casing port perfectly clean, check the wire lead loom for harness chafing against hot exhaust manifolds, and ensure a completely dry terminal interface to secure absolute telemetry reliability.
