toyota camry mass air flow sensor problems

The MAF sensor is a very accurate, but also a very delicate component. With no fuel wasted, the fuel economy is at its best, and it also reduces the negative effect on the environment.

The optimal air-fuel mixture leads to higher power output and ensures all the fuel gets used up. It has a “hot wire” which is heated to a constant temperature. The air flowing over it is trying to cool it down, and the exact volume of air can be measured by taking into account the electrical current necessary to heat the wire, with more airflow requiring a stronger current.įor modern fuel injection systems, precision is everything, and knowing how much air is available in every millisecond allows the ECU to adjust the fuel injection frequently. The mass airflow sensor measures the volume of air going into the throttle body. I strongly suggest that you read the following article as I’ll explain how the MAF sensor works, why it’s important and why you shouldn’t drive without it, even if the car is running better. If the car is running better with the MAF sensor unplugged, it means that the sensor is sending inaccurate readings and needs to be either cleaned or replaced. After unplugging it, the car seemingly runs better than it did with the MAF sensor. You’ve been trying to identify the cause of poor engine performance and your search lead you to the mass airflow sensor.
