Hella 013122421 Engine Crankshaft Position Sensor

HELLA Crankshaft Position Sensor 013122421

The HELLA Engine Crankshaft Position Sensor monitors crankshaft speed and position so the engine control system can manage timing with accurate input. 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.

Built 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.

Detailed Description

HELLA 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.

Compatible 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.

What It Helps Address

• Crankshaft speed or position signal loss
• Intermittent engine stalling or no-start conditions tied to sensor input
• Rough running caused by inaccurate crank signal data
• Check engine light concerns related to crankshaft position sensing
• Timing control issues from a worn or unstable sensor

Installation Notes

Installation 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.

Quality Assurance

HELLA 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.
