Product Details

Walker Products’ Complete Assembly program is built for applications where replacing the full housing is preferred to help keep the connector air tubes clean and reduce the chance of contamination affecting the sensor element. Part number 245-1280 is produced with OEM-quality components, custom engineered circuit boards, and production testing that verifies calibration before it is released for sale. Walker also states that many MAF sensors in this program are manufactured in the USA, and the brand has supplied fuel system and engine sensor components since 1946.

This Walker MAF sensor is designed to meet or exceed OE long-term fuel trim targets through calibrated airflow characteristics. If you are replacing a failing mass air flow sensor on a Honda Civic or Toyota Corolla, 245-1280 provides a complete housing-style solution for the airflow measurement system.

Common Problems This Part Can Help Solve

• Rough idle caused by inaccurate airflow readings
• Hesitation or stumble during acceleration
• Check engine light related to MAF sensor performance
• Poor fuel trim correction from a contaminated or failing sensor
• Driveability issues after intake contamination or sensor wear

Installation Notes and Tips

Before installation, inspect the intake tract and connector for dirt, oil, or damage. Because this is a complete housing assembly, verify the mounting points and connector style match the original unit. Avoid touching the sensing element with bare hands and confirm all air tubes and clamps are clean before reassembly. After installation, clear diagnostic trouble codes and verify idle quality and fuel trim readings.

Quality Assurance

Walker Products manufactures this sensor as a 100% new replacement and tests each unit for fit, form, and function before release. The brand is ISO 9001 and IATF16949 certified, with engineering and production processes focused on calibrated airflow performance and on-vehicle verification.
