If you notice the engine idling is lean or it is getting hard to turn it over, you can consider changing it.Īnother reason is the engine starts stalling once it starts or it begins to jerk or hesitate. There are so many reasons why you might be required to change your MAF. Once you disconnect the battery for ten minutes and replace it back, the computer will begin to learn all the parameters of the newly replaced MAF sensor. The reason you need to do this is for the car computer to reset to its factory setting and forget previously learned parameters. What to do after replacing mass air flow sensorĪfter you finish replacing your mass airflow sensor, you will have to let your car idle for about 30 minutes to an hour or you disconnect your car battery for some minutes (I recommend 10 to 15) and then reconnect it back again. If you change the air filter regularly, it will help to ensure your mass airflow sensor works perfectly and has a long life span. The MAF can also get dirty as time goes on due to an old or clogged air filter.Ī dirty filter will serve as a passage for dirt to enter the airflow sensor. The MAF can get damaged and once it does, it causes many problems which could lead to engine failure or a drastic reduction in performance.Ī faulty or damaged mass airflow sensor can cause rough idling to the engine and difficulties in starting. The MAF as it is commonly called is usually placed between the throttle and air cleaner. The ECU will then deliver the required amount of fuel to the engine. read also the 8 Symptoms of bad mass air flow sensor in my previous article. After collecting the information, the details will be sent to the Engine Control Unit. The airflow sensor collects details to determine the amount of needed fuel. The mass airflow sensor is the component used for detecting the flow of air that is entering the engine of a car. I also discussed the Mass airflow sensor replacement cost and much more.
Mass airflow sensor cost how to#
If you find what to do after replacing mass air flow sensor or maybe you like to know how to reset mass air flow sensor after replacement and how to trick a mass air flow sensor and if you should even perform the tricking in the first place, then you have come to the right place. You can find a mechanic near me with My Auto Shop.Last updated on July 13th, 2023 at 05:06 pm No, but it’s a cheap and easy part that provides a lot of benefits. They are a cheap and easy thing to replace so you should replace them as required. Some sensors last over 40,000km but usually they need replacing every 20-30,000km or just when they wear out. How often do I need a mass airflow sensor replaced? It’s a small and easy part to replace so prices can be as low as $35 and rarely go over $400 for twin sensor, performance vehicles. How much does a mass airflow sensor cost?
Mass airflow sensor cost code#
The engine will be run and the fault code removed. The new mass airflow sensor will be connected and plugged into the connector. Once the intake is located, the mechanic will disconnect the sensor and check the terminals on the electric connector. The bonnet will be opened and the intake located. A lot of the time a mechanic can use a diagnostic tool to figure out which sensor needs replacing and take the guesswork out.
If your car starts idling poorly at the lights, running low on power, gas mileage seriously reduced, or you get a check engine light, you may need a new MAF. How to tell if you need a new mass airflow sensor? As these are things you want to avoid, get it replaced when needs be.
Without it working properly, your car will run poorly, get bad gas mileage and stumble when idling. In order for your car to run as efficiently as possible and have the right air/fuel mixture, your MAF needs to work properly. It is the heating element that usually leads to a MAF failing as it wears out over its lifespan. More cooling means more air is flowing, less cooling means less air is flowing. The amount of cooling that occurs is what gives the ECU the info it needs. The MAF has a heated element that is cooled by the air flowing over the element. It is usually fitted in the air intake after the filter and before the intake plenum. It then sends this information to the ECU which will use this info to adjust the fuel mixture that is injected via the fuel injectors. The mass airflow sensor checks the amount of airflow that’s coming into the engine.
