Product Line Details

Walker’s Complete Assembly line offers a sensor and housing package for applications where replacing the full unit is preferred. This approach helps address contamination concerns in the air tube and housing area while providing a direct replacement format for vehicles that require the complete sensor assembly.

Detailed Description

Walker Products Part Number 245-1366 is engineered for precise airflow signal delivery to the engine control system. The sensor is calibrated and production-tested to support OE-style fuel trim performance, and the complete housing assembly helps simplify replacement on Land Rover Discovery, Range Rover, Range Rover Sport, Range Rover Velar, and LR4 models that call for this configuration. This part cross-references LR035726 for the same application.

What It Helps Fix

  • Rough idle caused by inaccurate airflow readings
  • Check engine lights related to mass air flow sensor faults
  • Hesitation or poor throttle response
  • Fuel trim issues from incorrect air measurement
  • Driveability problems after contamination or sensor wear

Installation Notes and Tips

Verify connector shape, terminal count, and housing style before installation. Because this is a complete assembly, inspect the intake tract and air tube surfaces for dirt or oil residue before fitting the new unit. Handle the sensing element carefully and avoid touching the sensor surface during installation. Confirm vehicle-specific fitment for the exact year and model before ordering.

Quality Assurance

Walker Products has supplied fuel system components since 1946 and operates as an ISO 9001 and IATF 16949 certified manufacturer. The 245-1366 mass air flow sensor is 100% new, programmed, and tested before release, with on-vehicle verification used to confirm calibration and function.
