Mass Air Flow Sensor for Volvo 850
The Spectra MA377 mass air flow sensor is built for 1993-1994 Volvo 850 applications with multiple MAF sensor configurations. It uses a programmable ceramic circuit board with a protective silicon coating to help resist under-hood heat swings and road vibration, while the platinum resistance thermometer design supports quicker signal response and consistent airflow measurement.
Key Features
- Fits 1993-1994 Volvo 850, N/A
- Programmable ceramic circuit board
- Silicon-coated protection against temperature fluctuation and vibration
- Platinum resistance thermometer sensor design
- Direct replacement part number MA377
Detailed Description
Built for emission control systems, the Spectra MA377 helps restore accurate airflow data to the engine control module. This mass air flow sensor is intended for Volvo 850 models from 1993-1994 and is listed for vehicles with multiple Mass Air Flow Sensor configurations. This part cross-references Bosch (e.g., 0280217002) for the same application.
What It Helps Address
- Rough idle caused by inaccurate airflow readings
- Hesitation during acceleration
- Check engine light related to MAF sensor performance
- Poor fuel control from incorrect air measurement
- Driveability issues tied to sensor signal inconsistency
Installation Notes and Tips
Verify the connector style and sensor configuration against the original unit before installation. Confirm the vehicle is a 1993-1994 Volvo 850 and match the replacement to the existing Mass Air Flow Sensor setup. After installation, clear diagnostic trouble codes and recheck idle quality and throttle response.
Quality Assurance
Spectra uses a ceramic circuit board design with protective silicon coating and platinum resistance thermometer sensor technology to support stable operation in demanding under-hood conditions.
