Hella 009121701 Engine Camshaft Position Sensor for BMW

The Hella 009121701 Engine Camshaft Position Sensor is a precision-engineered exhaust camshaft position sensor designed for BMW vehicles. This sensor provides critical real-time data to the engine control module (ECM) by accurately monitoring the camshaft's rotational position, enabling precise control of fuel injection timing and valve timing for optimal engine performance and efficiency.

Key Features:

• Hall effect sensor technology scans a ring gear on the camshaft for accurate position detection
• Provides essential data for precise injection and ignition timing optimization
• Engineered to withstand high temperatures, vibrations, and harsh engine compartment conditions
• Includes O-ring seal for proper installation
• Made in Germany with OE-quality construction and materials
• Meets or exceeds BMW factory specifications

A failing camshaft position sensor can cause a variety of drivability issues including hard starting, rough idle, stalling at low speeds, and poor engine performance. This Hella replacement sensor restores proper engine timing control and resolves these common problems. Cross-references to BMW OEM part numbers 12147518628 and 12141438082.
