Proper functioning of the MAF sensor ensures efficient engine operation, leading to improved fuel economy and reduced emissions. A faulty sensor can cause drivability issues such as rough idling, hesitation, stalling, and poor acceleration. PIERBURG is a reputable brand known for its high-quality engine management components.
