Detailed Description

HELLA 013122041 is an engine crankshaft position sensor used to report crankshaft position and rotational speed to the engine management system. That signal is critical for ignition timing and fuel control, especially in diesel applications where precise engine data matters. This sensor is listed for 2009-2013 BMW X5 and 2009-2011 BMW 335d, with the noted 3-pin connector and 226 mm cable length.

This part cross-references Bosch (e.g., 0 281 002 477) for the same application. If you are replacing a failing crankshaft sensor on a BMW X5 or BMW 335d, part number 013122041 provides the specified connector style and harness length needed for the listed vehicles.

What It Helps Fix

• Crankshaft speed or position signal loss
• Hard starting or no-start conditions caused by missing engine speed input
• Intermittent stalling related to crankshaft sensor signal issues
• Check engine light concerns tied to crankshaft position sensor faults
• Rough running from inaccurate engine timing data

Installation Notes and Tips

Verify the 3-pin connector, 226 mm harness length, and mounting point before installation. The product notes indicate assembly/disassembly by qualified personnel is required. Inspect the connector, wiring, and nearby engine components for heat or fluid damage before installing the new sensor.

For BMW X5 and BMW 335d applications, confirm the existing sensor matches the listed connector shape and cable length before ordering. Part number 013122041 should be matched to the vehicle by year and engine configuration using the fitment details provided.

Quality Assurance

HELLA builds this crankshaft position sensor with resistance to temperature shock, vibration, and engine fluids, and it is tested for durability under changing engine conditions. The design also focuses on reduced signal drift for stable engine control input.
