Walker 245-1348 Mass Air Flow Sensor

Walker Sensor Only Mass Air Flow Sensor 245-1348

Walker 245-1348 is a sensor-only mass air flow sensor built for direct replacement on select Jaguar applications. It is designed for drivers who need accurate airflow measurement, stable fuel trim control, and a clean OE-style fit without replacing the full housing assembly.

The Sensor Only line from Walker focuses on replacement sensors rather than complete housings. That makes it a practical choice when the original housing is serviceable and you want a faster, more economical repair path for a Jaguar XJR, XK, XKR, S-Type, or Super V8.

Product Details

Walker Products engineers its MAF sensors to match vehicle airflow requirements across the full flow range. Part number 245-1348 is calibrated and production-tested, with on-vehicle verification used to confirm performance. Walker also manufactures many of its high-demand sensors in the USA, and the brand has supplied fuel system components since 1946. This part cross-references Cardone Reman 74-50078 for the same application.

Compatible With 2005-2009 Jaguar Super V8, N/A; 2004-2009 Jaguar XJR, N/A; 2007-2009 Jaguar XK, N/A; 2003-2009 Jaguar XKR, N/A; and 2003-2008 Jaguar S-Type, N/A. If you are searching for a Jaguar XJR mass air flow sensor, Jaguar XK MAF sensor, or Walker 245-1348 for Jaguar S-Type applications, this part matches the listed fitment.

Common Issues This Part May Address

• Rough idle caused by inaccurate airflow readings
• Check engine light related to mass air flow sensor performance
• Hesitation or poor throttle response during acceleration
• Fuel trim imbalance from incorrect air measurement
• Driveability problems after MAF sensor contamination or failure

Installation Notes and Tips

Sensor-only replacement is typically used when the housing and air tubes remain in good condition. Before installation, inspect the connector, intake tract, and surrounding air path for dirt, oil residue, or damage. Handle the sensing element carefully to avoid contamination, and verify the connector shape, terminal count, and mounting points against the original part before installation.
