Spectra MA366S Mass Air Flow Sensor
The Spectra MA366S mass air flow sensor is built for precise airflow measurement and stable signal output in the engine management system. It is a direct-fit style replacement for select Ford Escort and Mercury Tracer applications, including 1991-1993 models with multiple mass air flow sensor configurations.
Key Features
- Programmable ceramic circuit board with premium-grade silicon coating
- Helps protect the sensor from under-hood heat swings and road vibration
- Uses platinum resistance thermometer sensor technology for consistent response
- Supports accurate airflow signal delivery to the engine control system
- Cross-references Delphi AF10110 and NGK 59021 for the same application
Detailed Description
The Spectra MA366S is engineered for 1991-1993 Ford Escort and 1991-1993 Mercury Tracer vehicles that use a mass air flow sensor in the intake system. Its circuit board design is built to maintain signal consistency under demanding operating conditions, while the platinum resistance thermometer sensors support faster response characteristics. For drivers searching for a 1991-1993 Ford Escort mass air flow sensor or a 1991-1993 Mercury Tracer MAF sensor, MA366S provides a focused replacement option.
This part number, MA366S, is also referenced in aftermarket catalogs under related numbers used for the same application, including Delphi AF10110 and NGK 59021.
What It Helps Address
- Rough idle caused by inaccurate airflow readings
- Hesitation during acceleration
- Hard starting related to incorrect air metering
- Check engine light concerns tied to airflow sensor performance
- Fuel trim issues from inconsistent sensor output
Installation Notes and Tips
Verify the original sensor part number and connector style before ordering. Confirm fitment against the vehicle’s existing mass air flow sensor configuration, since these Escort and Tracer applications note compatibility with multiple sensor versions. Inspect the intake tract, air filter housing, and wiring connector for contamination or damage before installation.
Quality Assurance
Spectra designs this sensor with a protected circuit board and platinum-based sensing elements to support stable operation in the engine bay environment. The MA366S is built for the listed Ford Escort and Mercury Tracer applications and is intended as a replacement sensor for those fitments.
