Give your engine's computer an accurate read on incoming air with the Walker Products Mass Air Flow Sensor 245-2015. It measures the mass of metered air entering the engine so the ECU can calculate the correct air-fuel ratio. It installs as a direct-fit replacement for the listed applications, including the 1990-1995 Ford Aerostar [V6-4.0L], 1991-1994 Ford Explorer [V6-4.0L], and 1990-1995 Ford Ranger [V6-4.0L] — see the Buyer's Guide tab for the full list.
- Precise air-flow measurement: reads incoming air so the ECU can trim the air-fuel mix accurately.
- 4-terminal female connector: designed for a straightforward plug-in replacement.
- New, never remanufactured: Walker MAF sensors are 100% new and tested for fit, form, and function, built to meet or exceed OE specifications and test requirements.
- Sensor-only replacement: housing is not included; supplied with replacement Torx screws and the corresponding tools.
Accurate air-flow data helps the ECU optimize the air-fuel mix for reliable monitoring. Watch for a rough idle, hesitation, stalling, poor fuel economy, or an illuminated check engine light — these can be signs the MAF sensor may need replacing, though the same symptoms can have other causes, so diagnose before replacing. Country of origin: China.
