Show original supplier description
The ACDelco 213-4337 Mass Air Flow Sensor is an essential component engineered to ensure optimal engine performance by precisely measuring the volume of air entering the engine. This critical function allows the engine control module (ECM) to accurately determine the correct fuel-air mixture, leading to efficient combustion and smooth operation. With OE-level quality, reliability, and fitment, this mass air flow sensor is a trusted replacement part for a variety of GM vehicles. The sensor's primary role is to provide real-time data on airflow, which directly impacts fuel injection calculations and overall engine efficiency. This ACDelco Mass Air Flow Sensor is compatible with a wide array of GM vehicles from 1999 to 2005, specifically models equipped with the 3.8 V6 engine, including various trims of Buick Regal, LeSabre, and Park Avenue; Chevrolet Camaro, Monte Carlo, and Impala; Oldsmobile 88, Intrigue, and LSS; and Pontiac Firebird, Grand Prix, and Bonneville. It is recommended to use the vehicle selector tool to confirm exact fitment for your specific application. Symptoms of a faulty mass air flow sensor can include poor engine performance, rough idling, decreased fuel efficiency, and check engine lights with codes such as P0101, P0102, P0103, P0104, or P0113. Replacing the ACDelco 213-4337 when these issues arise or during routine maintenance can help restore optimal engine function and fuel economy.
