The active fuel management system (AFM) is a technology used to reduce the amount of gasoline and diesel consumed by the engine and it is one of the technologies that contributes to better vehicle performance.
In addition, this system can help us save money on expensive gasoline prices by reducing fuel consumption. AFM technology allows you to switch from eight to four cylinders during the combustion cycle. Thus, the number of working cylinders is reduced at high speeds or when it is not necessary to have all eight cylinders in use.
When it comes to how to disable the active fuel management system, there are some factors that you need to consider before making a decision. If you are looking for how to reduce fuel consumption, you should use this technology carefully.
In addition, the AFM has some disadvantages. When the cylinders are off, there is a high amount of vibration and noise that can be very unpleasant for the driver’s ears.

The Ways to Disable Active Fuel Management
Installing the disabler is the first and most important step in turning off an AFM. That is not an easy process, to say the least. Disablers can be installed in the following manner:
How to connect:
It’s necessary to turn the engine off first. The OBD-II port must then be hooked into the disabler. The OBD-II port is located under the steering wheel. The steering wheel is also located underneath the dashboard..

Checking the Blue Light:
When the device is connected, a blue light should be visible. The gadget must be reconnected if the blue light does not appear. It’s possible that the port’s fuse has to be checked if that fails.
To check that the disabler is working effectively, the car should be started and driven for a time once it has been successfully linked.
Disabler Installation Tips: A Few Pointers to Keep in Mind
Before inserting the disabler, the vehicle’s engine must be turned off.
The disabler must be unplugged if the vehicle is not to be utilized for longer than four or five days. When the vehicle is driven, it should be reinstalled.
When the car is taken to a mechanic for a diagnostic, the same rules apply. The OBD-II port must be utilized for diagnostic purposes since the car will be scanned. Because of this, disconnecting the disabler from the port is preferable.
Only if the vehicle’s valve train is in good functioning order should a disabler be placed.
After installing the disabler, the AFM will be disabled and the computer will no longer be able to return to 4-cylinder mode. For as long as the driver desires, the 8-cylinder mode can be used. AFM will also enhance the exhaust sound, giving the vehicle a race car feel.
In certain cases, removing the AFM rather than turning it off is preferable. It’s not cheap to get rid of the AFM, though, since you’ll need a deletion kit and other parts. The procedure is time-consuming and complicated. The only alternative left is to use a deletion kit when the lifter fails to function.
It is possible to use a disabler if the situation is dire and it is impossible to satisfy the conditions for installing a deletion kit and its components. The solenoid pack of the AFM must be linked and all the codes must be in order to achieve this goal.
It doesn’t matter if it’s the original valley cover or a non-AFM one, this may be done. The solenoid pack has to be attached to the harness and installed. For the time being, this will suffice.
Once the disabler is ready, disabling the AFM is a cinch.
The Price of AFM
There are a wide variety of AFM disablers on the market from various manufacturers. The more expensive a disabler is, the less efficient it is at disabling an AFM. There is a direct correlation between price and quality. Between $150 and $250, on average, the disablers are sold.
Should I Disable or Delete AFM?
We recommend deactivating AFM unless you have failing lifters. It’s more expensive to remove AFM than it is to install it, because you’ll need to replace a lot of components and gaskets, as well as a lot of work, if you’re not doing it yourself.
If you desire, you can always switch it back on at any time after disabling it. The manufacturing warranty is maintained and you may reinstall it if something goes wrong as a result of disabling it.
Install a disabling device if lifters fail, or replace the lifters and install the device. If you have to get to the lifters to replace them, the only reason we mention eliminating it is because doing so doesn’t involve a lot of more effort.
We advocate changing the oil pump in both cases, however I suppose I should remark that few people do so unless they are entirely erasing the system. The decision is entirely up to you, although it’s not a terrible idea to disable it in the first place.
What Are the Disadvantages of Using the Advanced Flight Management System?
Despite the fact that the AFM system contributes to improved fuel efficiency, there are certain issues linked with it. The following are some of the disadvantages of employing an Active Fuel Management system:
It is possible that oil will pass through the piston and into the combustion chamber. In the event that oil is burned off or accumulates in the combustion chamber, it has the potential to become a severe problem in the future.
The majority of automobile owners do not love the sensation of having half of their cylinders shut off or of having their autos converted from full on to half off.
Lifters that are not operating properly: The AFM system continually keeps the lifters operational by deactivating and reactivating them on a regular basis. It’s possible that the lifters may need to be replaced soon.
If you find yourself in a situation where you need to turn off your car’s AFM, you’ll at least be prepared. Get a decent disabler, follow installation instructions, take precautions, and disable the AFM so that you can enjoy your drive!
