Mercedes Camshaft Position Sensor - Facet 0021539528

Product Information

The engine camshaft position sensor is used to aid the engine ECU in monitoring the position of the engine camshaft. The feedback from this sensor is used for the optimization of the engine ignition timing. This sensor is sometimes referred to as a CMP sensor and is critical for proper engine operation. Failure of the camshaft position sensor can cause several driveability complaints including stumbling, hesitation on acceleration, and power loss, as well as potentially cause hard start on no-start conditions.

• Check engine light (CEL)
• Extended crank or no-start condition
• Poor driveability including stumbling, hesitation on acceleration, and power loss.

About Facet

Facet began in 1946 by Francesco Andriano with the core principles of dedication, skill, courage to do, and to innovate when he opened up his laboratory. Soon after WWII, Franceso Andiano founded F.A.C.E.T with his son Mario. They began creating tungsten contacts for the telephone industry which was then a potential market with rapid growth. Due to the materials used, they were able to enter into another market, now producing plated contacts for ignition components in the Automotive Industry. In 1961 the company expanded by now producing condensers followed by caps and rotors in 1966. Since the early 90's, FACET has transformed to accommodate the arrival of electronics which as been a large part to this day. Since then, FACET has put a strong emphasis on continuous process improvements which continue to this day.
