Hella 013122631 Engine Crankshaft Position Sensor

The Hella 013122631 is a direct-replacement engine crankshaft position sensor engineered to OEM-level standards. Crankshaft position sensors (also referred to as crank sensors or CKP sensors) are critical engine management components that detect the rotational speed and precise angular position of the crankshaft, transmitting that data to the engine control unit (ECU).

The ECU relies on this signal to calculate and deliver accurate fuel injection timing and ignition pulses, making a properly functioning crankshaft sensor essential for smooth starting, stable idle, and optimal engine performance. A failing crank sensor commonly triggers diagnostic trouble codes P0335, P0336, P0337, or P0338 and may cause hard starts, misfires, rough idle, or unexpected stalling.

Key Features:

• Manufactured to OE specifications for precise fit and reliable signal output
• Built for durability — resistant to vibration, heat, moisture, and engine bay contaminants
• Delivers high measuring accuracy across a wide operating temperature range
• Plug-and-play replacement restores proper engine timing and fuel management
• Professional installation by qualified personnel is recommended

Hella is a global Tier 1 OEM supplier and one of the world's largest automotive parts manufacturers, with over 120 years of experience developing sensors and electronic components for virtually every major automaker. The 013122631 reflects that same OE engineering expertise in an aftermarket-ready package.
