This standard replacement sensor uses an inductive design with a rectangular 1-connector layout and 2-pin blade terminals for a direct-fit style service part.\u003c\/p\u003e\u003cp\u003eBuilt with a plastic housing, black finish, and 12V electrical specification, HELLA 013122421 is engineered for resistance to temperature shock, vibration, and exposure to engine fluids. It is a practical replacement choice for Nissan Maxima, INFINITI I30, Nissan Pathfinder, and INFINITI QX4 applications that use a front-of-engine crank sensor location.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eEngine crankshaft position sensor for speed and position signal input\u003c\/li\u003e\n\u003cli\u003eInductive sensor design for engine management systems\u003c\/li\u003e\n\u003cli\u003eStandard replacement grade\u003c\/li\u003e\n\u003cli\u003ePlastic housing with black finish\u003c\/li\u003e\n\u003cli\u003e12V electrical specification\u003c\/li\u003e\n\u003cli\u003e1 rectangular connector, male connector gender\u003c\/li\u003e\n\u003cli\u003e2 blade terminals, female terminal gender\u003c\/li\u003e\n\u003cli\u003e2 mounting holes with 7.00 mm diameter\u003c\/li\u003e\n\u003cli\u003eNo gasket or seal included\u003c\/li\u003e\n\u003cli\u003eNo wiring harness or mounting bracket included\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDetailed Description\u003c\/h2\u003e\u003cp\u003eHELLA 013122421 is an engine crankshaft position sensor that provides the engine control module with crankshaft speed and position data. That signal is critical for ignition timing and fuel control, especially in vehicles that rely on a front-of-engine sensor location. This part cross-references Dayco 87624 for the same application.\u003c\/p\u003e\u003cp\u003eCompatible With 1995-2001 Nissan Maxima, front of engine; 1996-2001 INFINITI I30, front of engine; 2001-2002 Nissan Pathfinder, front of engine; and 2001-2003 INFINITI QX4, front of engine. The HELLA 013122421 part number is also commonly searched alongside these Nissan and INFINITI fitments.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCrankshaft speed or position signal loss\u003c\/li\u003e\n\u003cli\u003eIntermittent engine stalling or no-start conditions tied to sensor input\u003c\/li\u003e\n\u003cli\u003eRough running caused by inaccurate crank signal data\u003c\/li\u003e\n\u003cli\u003eCheck engine light concerns related to crankshaft position sensing\u003c\/li\u003e\n\u003cli\u003eTiming control issues from a worn or unstable sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eInstallation requires qualified personnel. Verify the connector shape, 2-pin terminal layout, and front-of-engine mounting location before replacement. Inspect the mating harness, mounting points, and surrounding engine area for heat damage, fluid contamination, or corrosion before installing the new sensor. Because no gasket, seal, wiring harness, or mounting bracket is included, reuse or source those items separately if needed.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eHELLA tests this sensor for durability under temperature changes, vibration, and exposure to engine fluids. The design also focuses on reducing signal drift and improving resistance to temperature shock for stable engine control input.\u003c\/p\u003e","brand":"Hella","offers":[{"title":"Default Title","offer_id":52415112675509,"sku":"BFDP-013122421","price":30.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/1442\/1173\/files\/HL_013122421_Fro.jpg?v=1777801551","url":"https:\/\/www.partcatalog.com\/products\/hella-013122421-engine-crankshaft-position-sensor","provider":"PartCatalog","version":"1.0","type":"link"}
