What should the mass air flow sensor reading be?
Note: The transmission may need to be put into a lower gear to create a sufficient load on the engine. At WOT, the MAF sensor reading should be approximately 40 times the engine displacement. For example, if your vehicle has a 1.8L engine, the MAF reading should be approximately 72 g/s (1.8 x 40 = 72).
Why is the Check Engine light still on after cleaning mass airflow?
If it is the MAF, and cleaning it was unsatisfactory, it will be need to be replaced. There are many possible causes for the Check Engine Light to come on besides the mass airflow sensor, so have an expert read the codes and address the Check Engine Light accordingly. Was this answer helpful? Thank you for your feedback! Sorry about that.
What should the air flow sensor read at idle?
At idle, the approximate air flow rate (in g/s) should loosely mirror the size of the engine (measured in liters). For example, if you have a 1.8L engine, the reading should be close to 1.8 g/s. As you’ll see in the image below, which is of a Honda 1.8L engine with a healthy MAF sensor, there’s a reading of 2.27 g/s at idle.
What should MAF reading be for 1.8L engine?
For example, if your vehicle has a 1.8L engine, the MAF reading should be approximately 72 g/s (1.8 x 40 = 72). If the engine has variable valve timing (VVT), the MAF sensor reading should be approximately 50 times the engine displacement.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
Where is the mass air flow sensor located?
Updated: February 18, 2020 A Mass Air Flow sensor (MAF) is one of the key components of an electronic fuel injection system in your car. It is installed between the air filter and the intake manifold of the engine.
How to clean a dirty mass air flow sensor?
How to clean a Dirty mass air flow sensor. Sometimes you may be able to extend the life of the mass air flow sensor by cleaning it. As explained above, the sensor can become covered in grease and dirt and this can affect its performance. In my experience, if the engine is performing very badly, then the sensor may be worn as well as dirty.
What kind of air flow sensor do I need for my MAF?
Depending on the year and make of the vehicle, you may find different types of mass air flow sensors, from the old-style vane air flow meter to the modern era hot-wire mass air flow meter. Since hot-wire technology is the most widely used today, we’ll assume that your MAF is using that design.
