Walker Products 245-1098 Mass Air Flow Sensor Assembly

A mass air flow sensor, also known as a MAF sensor, is an important component in modern automotive engines. It measures the amount of air entering the engine, allowing the engine control module (ECM) to adjust the fuel delivery and optimize the air/fuel ratio for maximum performance and fuel efficiency. If your vehicle's MAF sensor is malfunctioning, it can cause a number of problems, including poor fuel economy, reduced power, and even stalling. Fortunately, replacing a faulty MAF sensor is relatively simple and inexpensive, and can restore your vehicle's performance and efficiency.

• Measures the amount of air by weight through changing voltages or frequencies
• Sends information collected to the onboard computer
• The computer uses this and other inputs to calculate the correct amount of fuel delivered
• Symptoms of failure include poor starting, engine surging, engine stalling, a check engine light, and no-start conditions
• Sensors are non-serviceable, replace sensors that are non-functional
