Hella 013122811 Engine Crankshaft Position Sensor with Seal Ring - 2-Pin

The Hella 013122811 is a direct-replacement crankshaft position sensor (crankshaft pulse sensor) engineered to OE specifications. This sensor monitors the rotational speed and precise position of the crankshaft, delivering accurate signal data to the engine control unit (ECU) to enable correct calculation of fuel injection and ignition timing.

Key Features:

• 2-pin connector for straightforward, plug-and-play installation
• Seal ring included — no need to source additional hardware
• Manufactured to original equipment (OE) standards for reliable, long-lasting performance
• Precise signal output supports accurate injection and ignition pulse timing
• Built to withstand the demanding thermal and mechanical environment of the engine bay
• Sourced from HELLA, a globally recognized OE supplier to major automotive manufacturers

A faulty crankshaft position sensor can trigger diagnostic trouble codes such as P0335, P0336, P0337, or P0338, and may cause symptoms including hard starting, engine misfires, rough idle, or poor acceleration. The Hella 013122811 restores correct sensor function and helps clear these fault conditions.
