Detailed Description

Walker Products designs MAF sensors with tuned flow characteristics across the operating range so the engine control system can measure incoming air accurately. This helps maintain fuel trim performance close to OE expectations and supports consistent drivability on the Ford Transit Connect. Part number 245-1588 is part of Walker’s Sensor Only program, which is intended for applications where replacing the sensor alone is the correct service approach.

Walker has supplied fuel system components since 1946 and manufactures as an ISO 9001/IATF 16949 certified company. Many Walker MAF sensors are produced in the USA, and each unit is verified through production testing and on-vehicle validation.

This part cross-references Standard Ignition MAS0506 for the same application.

What It Helps Fix

• Rough idle caused by inaccurate airflow readings
• Hesitation or poor throttle response
• Check engine light related to mass air flow sensor faults
• Lean or rich fuel trim conditions
• Reduced fuel economy from incorrect air metering

Installation Notes and Tips

Fits 2019-2023 Ford Transit Connect, sensor only. Confirm the connector style, 4-terminal pin layout, and oblong 1-connector design before installation. Inspect the air inlet tract and connector area for contamination, and avoid touching the sensing element with bare hands. If the original housing is damaged or contaminated, replace the complete assembly instead of the sensor alone.
