Keep your engine's fuel metering on track with the Standard Ignition Mass Air Flow Sensor MAS0114. It drops in as a direct-fit replacement for the 1999-2000 Ford Contour, 2000-2002 Mercury Cougar, and 1999-2000 Mercury Mystique, reporting how much air is entering the engine so the powertrain control module can meter fuel to match.
- Measures intake airflow: monitors the mass of metered air entering the engine and sends that reading to the powertrain control module.
- Supports fuel metering: the airflow signal helps the PCM calculate the correct fuel delivery to maintain the intended air-fuel ratio.
- Direct-fit replacement: a straight replacement for the mass air flow sensor on the listed applications.
Signs the sensor MAY need replacing include rough idle, hesitation or stalling, reduced fuel economy, and an illuminated check engine light. Because these symptoms can have other causes, diagnose the fault first; if a failed mass air flow sensor is the cause, this unit replaces it.
Interchange: Manufacturer part number MAS0114.
Frequently Asked Questions
What does this mass air flow sensor do?
It measures the mass of metered air entering the engine and reports it to the powertrain control module, which uses that reading to calculate the correct fuel delivery for the current air-fuel ratio.
What are the signs my mass air flow sensor may need replacing?
Common signs include rough idle, hesitation or stalling, reduced fuel economy, and an illuminated check engine light. These symptoms can have other causes, so diagnose the fault before replacing.
What vehicles does MAS0114 fit?
It is a direct-fit replacement for the 1999-2000 Ford Contour, 2000-2002 Mercury Cougar, and 1999-2000 Mercury Mystique. See the Buyer's Guide tab to confirm your vehicle.
Does it measure air or an air-fuel mixture?
It measures metered air only. The sensor reports intake airflow to the PCM, which then determines the fuel needed to reach the intended air-fuel ratio.
Should I diagnose the problem before installing this part?
Yes. The symptoms it addresses can stem from other components, so confirm the mass air flow sensor is the cause first; if it is, this unit replaces it.
