Give your engine computer an accurate read on incoming air with the Walker Products Mass Air Flow Sensor 245-1193. This complete MAF sensor and housing assembly is a direct-fit replacement for the 1999-2000 Ford Contour, 1999-2002 Mercury Cougar, and 1999-2000 Mercury Mystique with the L4-2.0L engine.
The sensor measures the air entering the engine and reports it to the ECU, which uses that data to manage the air-fuel ratio. Walker describes its MAF sensors as 100% OEM quality, precision made, and built to original equipment specifications and test requirements.
- Precise air flow measurement: Designed to give accurate readings of incoming air so the ECU can meter fuel correctly.
- Custom-tuned calibration: Walker engineers tune the flow characteristics across the full flow spectrum. The sensors are designed to meet or exceed OE long-term fuel trim percentages.
- Fully tested: Every sensor is programmed and tested for fit, form, and function. Calibrations go through 100% production testing and are verified with on-vehicle testing.
- Complete housing assembly: Some manufacturers recommend replacing the full housing so the air tubes are clean and the sensing element is protected from oils on your hands and from air pollution.
Signs this part may need replacing include hesitation, rough idle, stalling, reduced fuel economy, or an illuminated check engine light. These symptoms can have other causes, so diagnose the system before replacing the sensor. Walker has supplied fuel system components since 1946 and is an ISO 9001 / IATF 16949 certified manufacturer.
