What Role Does a Bad Mass Air Flow Sensor Play in Engine Sputtering in Suzuki Alto Lapin?

Can a faulty Mass Air Flow MAF sensor lead to engine sputtering in the Suzuki Alto Lapin? How does the MAF sensor affect the air-fuel ratio and overall engine performance? What are the symptoms of a failing MAF sensor, and how can it be diagnosed? Can a bad MAF sensor cause the engine to misfire, sputter, o r lose power?

A malfunctioning Mass Air Flow MAF sensor can lead to engine sputtering in the Suzuki Alto Lapin by disrupting the air-fuel mixture:

How the MAF Sensor Works: The MAF sensor measures the amount of air entering the engine and sends this data to the engine control unit ECU. The ECU uses this information to adjust the fuel injection accordingly. A bad MAF sensor provides inaccurate data, leading to an incorrect air-fuel mixture, which can cause sputtering o r poor engine performance.
Symptoms of a Bad MAF Sensor: Common signs include engine sputtering during idle o r acceleration, poor fuel efficiency, engine stalling, rough idle, and hesitation when pressing the accelerator. The check engine light may also illuminate, and diagnostic trouble codes DTCs related to the MAF sensor will often be stored in the ECU.
Diagnosis and Repair: The MAF sensor can be tested with a diagnostic scanner. If the sensor is found to be faulty, it should be cleaned o r replaced. A professional mechanic can help ensure the correct part is installed and the sensor is calibrated properly.
Replacing o r cleaning the MAF sensor will help restore proper air-fuel ratio control and eliminate sputtering.
