Hella 009121321 Engine Camshaft Position Sensor

The Hella 009121321 is an OE-quality engine camshaft position sensor engineered to accurately monitor the rotational position of the camshaft and deliver real-time data to the engine control unit (ECU). This signal allows the ECU to precisely synchronize fuel injection and ignition timing for optimal engine performance and efficiency.

Hella engineers this sensor to original equipment standards, drawing on decades of OEM manufacturing expertise. The result is a direct-fit replacement that delivers the same measuring precision, durability, and service life expected from a factory component — with highest measuring accuracy across a wide ambient temperature range.

Key Features:

• Monitors camshaft position to optimize fuel injection and ignition timing
• Manufactured to OE specifications for precise fit and reliable performance
• High measuring accuracy across a wide operating temperature range
• Trusted by automotive professionals and OEM partners worldwide
• Direct replacement — no modifications required
• Compatible with Lancia, Saab, Opel, Fiat, and additional European vehicle applications

Common symptoms of a failing camshaft position sensor include rough engine idle, hard starting, and an illuminated check engine light — often accompanied by diagnostic trouble codes P0340 or P0341. Replacing the failed sensor with the Hella 009121321 restores proper engine management system operation.
