4. Mass Airflow Sensor may fail and need replacing.
With a bad sensor, the engine will not know the right amount of fuel to add, causing problems including poor gas mileage, lack of power and more.
What if I don't replace my Mass Airflow Sensor?
- All cars take outside air and pass it into the engine through the air filter. The mass airflow sensor measures the amount of air entering the engine.
- For an engine to perform properly, it needs a specific amount of air-fuel mixture.
- The car's computer reads the amount of air coming into the engine from the mass airflow sensor and then calculates the correct amount of fuel needed for proper engine performance.
- If the sensor goes bad, the engine will not know the right amount of fuel to add, causing problems including poor gas mileage, lack of power and more.
- If the air filter is dirty it is common for the mass airflow sensor to get dirty and lose the ability to read the amount of air coming in the engine.
- Routinely changing your air filter can improve the lifespan of your mass airflow sensor
