Beck/Arnley 158-1815 Mass Air Flow Sensor

The Beck/Arnley 158-1815 Mass Air Flow Sensor (also called an air mass sensor or MAF sensor) measures the air entering the engine. It sends that reading to the engine control unit, which uses it to meter fuel correctly.

Key Features:

• Matches OE form, fit and function
• Corrosion-resistant terminals and coatings
• Built to withstand the engine environment
• Flange mount design
• May come with or without a housing, depending on the original equipment design

A service manual may call for a relearn or reset procedure after installation. If symptoms continue, check the rest of the intake system for vacuum leaks, a dirty air filter, and damaged wires or connectors.
