Detailed Description

This Walker mass air flow sensor 245-1206 measures incoming air so the engine control system can calculate fuel delivery more accurately. Proper airflow signal input is important for drivability, idle quality, and emissions performance on applications including 2009-2015 Chevrolet Silverado 2500 HD, 2009-2015 GMC Sierra 3500 HD, and 2009-2014 Cadillac Escalade. It also covers additional Silverado, Sierra, Tahoe, Yukon, Suburban, and CTS applications listed in the fitment data.

What It Helps Address
