xOverview
The OTO-KAUTOPARTS Mass Air Flow (MAF) sensor is designed as a dependable replacement for a wide range of Chevy and GMC models from the late 1990s to the early 2000s. It mirrors the original part’s form factor and electrical interface to help it drop in with minimal tweaks, so you can get back to your normal driving routine sooner.
What this MAF sensor does
In simple terms, the MAF sensor measures the volume of air entering the engine and converts that data into an electrical signal read by the vehicle’s ECU. This signal helps the ECU fine-tune fuel delivery and ignition timing, contributing to stable idle, smoother transitions, and consistent response across different driving conditions.

Why consider this replacement
