Walker 245-1662 Mass Air Flow Sensor

Walker 245-1662 Mass Air Flow Sensor

Walker 245-1662 is a sensor-only mass air flow sensor for select Jaguar applications. It is built as a new replacement part, programmed and tested before release, with fit, form, and function verification for the intended vehicle applications.

Walker Products’ Sensor Only line is designed for buyers who want a direct replacement MAF sensor without replacing the housing assembly. This approach is often used when the housing is still serviceable and the connector air path is clean. Fits 2001-2008 Jaguar X-Type, sensor only, and other listed Jaguar models below.

Key Features

• Sensor-only mass air flow sensor design
• Black housing color
• Male connector with rectangular shape
• 5-terminal spade connection
• 2 mounting holes
• No housing included
• No mounting hardware included
• 100% new, not remanufactured
• Programmed and tested for fit, form, and function
• Custom flow calibration for OE-style fuel trim performance

Detailed Description

Walker 245-1662 is part of Walker Products’ Sensor Only program, which focuses on direct-fit replacement MAF sensors for vehicles that do not require a complete housing assembly. The sensor is engineered with custom tuned flow characteristics and production-tested calibration to support accurate airflow measurement across the operating range. Walker also manufactures many of these sensors in the USA using OEM-quality components and custom circuit board programming.

This part cross-references DENSO Auto Parts 197-6030 for the same application. It is a direct replacement choice for Jaguar XF, Jaguar Vanden Plas, Jaguar XJ8, Jaguar S-Type, Jaguar X-Type, and Jaguar XK8 applications listed in the fitment data. The part number 245-1662 is useful when searching for a sensor-only replacement for these Jaguar models.

What It Helps Address

• Rough idle caused by inaccurate airflow readings
• Lean or rich fuel trim conditions related to MAF signal errors
• Check engine lights tied to mass air flow sensor faults
• Poor throttle response from incorrect incoming air measurement
• Driveability issues after contamination or sensor wear

Installation Notes

• Confirm the connector shape, terminal count, and mounting pattern before installation.
• Inspect the air inlet tract and connector area for dirt, oil, or debris before fitting the sensor.
• Sensor-only replacement is appropriate when the housing remains in serviceable condition.
• Handle the sensing element carefully to avoid contamination during installation.
• Verify the vehicle application by year, make, and model before ordering.
