Poor Performance in Malaysia? A Dirty MAF Sensor Could Be Choking Your Engine | MyMechanic

The Engine's Breathalyzer: What is a MAF Sensor?

The MAF sensor is located in your engine's air intake tube, right after the air filter. Its sole job is to measure the precise mass of air entering the engine. It does this by heating a tiny, delicate wire and measuring how much that incoming air cools it down. This data is sent to the engine's computer (ECU), which then calculates the exact amount of fuel to inject for the perfect air-fuel ratio.

How a Dirty Sensor Causes Big Problems

Over time, fine dust, pollen, and oil vapor can bake onto the sensor's delicate wire, insulating it. A dirty sensor can't accurately measure the airflow and will send incorrect data to the ECU. This leads to a host of performance issues:

  • Hesitation and Jerking: The car may stumble or hesitate when you press the accelerator because the ECU isn't providing enough fuel for the amount of air coming in.
  • Loss of Power: Your car will feel noticeably weaker and slower, especially when going uphill or trying to overtake.
  • Poor Fuel Economy: The ECU may overcompensate for the bad readings by injecting too much fuel, causing your fuel consumption to spike.
  • Check Engine Light: A dirty MAF sensor can trigger fault codes related to a "lean" or "rich" running condition.
