This Mass Air Flow (MAF) sensor measures the volume and density of air entering the engine, providing this data to the engine control module for optimal fuel mixture calculation. It is manufactured to meet precise OEM specifications, ensuring accurate airflow readings unlike a dirty or failing sensor that can cause incorrect fuel delivery. Operators may observe rough idling, poor acceleration, decreased fuel economy, or a check engine light if this MAF sensor is malfunctioning.

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A common initial symptom is an unstable idle or hesitation during acceleration. If ignored, the engine may run rough, experience significant power loss, and show a persistent check engine light with codes related to air-fuel mixture. Continued operation with a faulty MAF sensor will lead to poor fuel efficiency and can potentially cause damage to the catalytic converter.
Ensure the air intake tract is completely clean and free of debris before installing the new sensor to prevent contamination. Do not touch the sensor element directly, as oils from your skin can affect its accuracy.
Inspect the air filter and air intake hoses for leaks or damage when replacing the Mass Air Flow sensor.
