Walker Products 245-1091 Mass Air Flow Sensor Assembly Steering & Suspension Tools Operational Temperature: -40°F ~ +85°FMass airflow sensors measure the amount of air by weight through changing voltages or frequencies and sends this information 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.
