Hella 013122101 Engine Camshaft Position Sensor

The Hella 013122101 is an OE-quality engine camshaft position sensor engineered to monitor the rotational position of the camshaft and deliver precise data to the engine control module (ECM). The ECM uses this signal alongside crankshaft position data to calculate optimal ignition timing and fuel injection timing, keeping the engine running efficiently and cleanly.

How It Works:

This sensor operates on the Hall effect principle, scanning a ring gear mounted on the camshaft. As the ring gear rotates, it produces a change in Hall voltage within the sensor's IC, which is transmitted as a digital signal to the engine control unit for real-time processing.

Key Features:

• OE-specification design ensures direct-fit, plug-and-play replacement
• Hall effect sensing technology delivers high measurement accuracy across a wide temperature range
• Flange-mount design for secure, vibration-resistant installation
• Corrosion-resistant materials and robust housing construction for long service life in harsh underhood environments
• 12V DC operating voltage compatible with standard automotive electrical systems
• Digital output signal for clean, reliable communication with the ECM

Replacing a faulty camshaft position sensor restores proper ignition and fuel injection timing, resolving symptoms such as hard starting, rough idle, misfires, reduced power, and an illuminated check engine light. The Hella 013122101 is manufactured to meet or exceed original equipment standards, making it a dependable choice for professional technicians and DIY mechanics alike.
