Wells 5S13836 Mass Air Flow Sensor

The Wells 5S13836 Mass Air Flow Sensor is a direct replacement sensor designed to restore proper engine performance and fuel efficiency. This sensor measures the amount of air entering the engine and transmits that data to the engine control module (ECM), which uses the information to calculate the optimal air-fuel mixture for efficient combustion.

Key Features:

• Direct replacement for OEM part numbers 10393948 and 23256991
• Precision-manufactured sensing element ensures accurate airflow measurement
• Restores proper throttle response and eliminates rough idle conditions
• Helps improve fuel economy and reduce emissions
• Quality-tested to meet or exceed OEM specifications

Mass Air Flow Sensors are critical components in modern fuel injection systems. When a MAF sensor begins to fail, symptoms typically include rough idling, poor acceleration, decreased fuel economy, and illuminated check engine lights. Wells Vehicle Electronics has been manufacturing automotive electrical components for over 120 years, providing reliable replacement parts for professional technicians and DIY enthusiasts.
