Detailed Description

This Facet throttle position sensor, part number 10.5079, is used in emission control systems to report throttle angle to the vehicle’s control electronics. It fits 1991-1995 Volvo 940, 1990-1993 Volvo 240, 1985-1992 Volvo 740, 1985-1990 Volvo 760, 1987-1991 Volvo 780, and 1985 Volvo 745 applications, along with select BMW M3, M5, M6, 325e, 325es, and 528e models. This part cross-references Bosch references such as 0280120325 for the same application.

What It Helps Address

• Throttle signal errors that affect acceleration response
• Rough idle caused by incorrect throttle angle input
• Fuel delivery issues tied to inconsistent sensor output
• Check engine concerns related to throttle position feedback
• Driveability problems on Volvo and BMW fuel-injected systems

Installation Notes and Tips

Verify connector style and stamped reference numbers before installation, especially on BMW applications with rectangular connectors and Volvo applications marked Bosch or 0280120325. Confirm the sensor matches the vehicle year, make, and model exactly, since fitment varies by chassis and production range. After installation, clear any stored fault codes and confirm throttle response at idle and during gradual pedal input.

Quality Assurance

Facet manufactures ignition and engine management components for service replacement use, and this sensor is cataloged for the listed Volvo and BMW applications.
