Report: Faulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy
Mercedes-Benz S500 Problem
Average Mileage: 115,000 mi (85,000 mi - 145,000 mi)
A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.
