Keep your engine's fuel metering accurate with the Walker Products Mass Air Flow Sensor 245-1363. It drops in as a direct-fit replacement across a range of Land Rover, Range Rover, and Jaguar applications, measuring the mass of air entering the intake so the ECU can calculate the correct fuel delivery. When the original sensor drifts or fails, the engine loses the clean air reading it depends on.
Core job: Measures incoming air mass and sends that signal to the engine control unit for proper air-fuel calculation.
Direct-fit: Designed to install for the listed applications without modification.
Signs it may need replacing: Rough idle, hesitation or stumble on acceleration, stalling, reduced fuel economy, or an illuminated check engine light — diagnose the cause first, and if a failed MAF sensor is behind it, this replaces it.
Fitment: 1987-1995 Land Rover Range Rover · 1988-1994 Jaguar Vanden Plas · 1988-1994 Jaguar XJ6 · 1993 Land Rover Defender 110 · 1993-1995 Jaguar XJS · 1993-1995 Range Rover · 1994-1995 Land Rover Defender 90 · 1994-1995 Land Rover Discovery. See the Buyer's Guide tab for the full list.
It measures the mass of air entering the engine's intake and reports that signal to the ECU, which uses it to calculate the correct fuel delivery.
Which vehicles does the 245-1363 fit?
It's a direct-fit replacement for listed Land Rover, Range Rover, and Jaguar applications from 1987-1995. Check the Buyer's Guide tab to confirm your exact year and model.
What are the signs of a failing MAF sensor?
Common signs include rough idle, hesitation on acceleration, stalling, reduced fuel economy, or a check engine light. Diagnose the cause before replacing, as these symptoms can have other sources.
What interchange numbers does this replace?
It cross-references 5S2837, 74-10218, 74-10220, ERR5198, ESR1057L, FDM974, 19754, and SU5132.
Will replacing the MAF sensor fix my rough idle?
If a failed mass air flow sensor is the cause of the rough idle, this replaces it. Because other components can cause the same symptom, confirm the diagnosis first.
