How to Prevent AFM Lifter Failure

Active fuel management often referred to as AFM, is a subset of that genre that has nothing to do with the rest.

There have been hundreds of reports of drivers experiencing difficulties due to AFM lift failures. Only by understanding how to prevent AFM lift failures can you remove this menace from the list of concerns in your life.

Those of you who have been suffering from AFM for a long time will find some of the information I am going to offer today to be very beneficial.

What Causes Afm Lifter Failure?

The failure of a lifter is due to a specific reason. The most fundamental and frequently discovered reason is oil pressure problems, as well as control problems under certain circumstances.

If you would like more specific information, I have identified the three most typical reasons for AFM lifter failure.

Poor quality oil

The failure of the AFM lift was caused by poor quality oil, according to a statement from the company responsible for the elevator’s maintenance.

Depleted oil

Safety experts believe that lack of lubrication is responsible for lifter failure. An adequate amount of oil must be available for the sliding surface to work or operate at a satisfactory level.

General wear

The AFM lift is a vehicle component that is used regularly. It can wear out over time, but there is nothing you can do about it.

How To Prevent AFM Lifter Failure

It is impossible to prevent lifters from constantly malfunctioning. The only thing that can be done is to keep them in good condition so that they have a longer life.

Make sure the oil is of excellent quality.

Poor quality engine oil can affect the quality of a car’s tappet. Be sure to check the oil you use before you start using your vehicle’s tappet, and change it if necessary. The best way to keep it in good condition is to change it regularly.

Ensure a sufficient oil supply

Make sure your bike’s sliding surfaces receive enough oil to keep them free of loads. Receiving too much oil in the wrong place can decrease the likelihood of breakage and premature failure. Apply an adequate amount of oil to the surface if necessary.

Use an AFM disable.

If you want to keep things simple, a decent AFM deactivator is an excellent choice. Because they are so simple to operate, they take less time to activate and can be deactivated in an instant. Lifters will be needed less often if you use the AFM less frequently.

Update components

A new version of the AFM lifting system has been developed to reduce the risk of failure. The new design reduces the frequency of AFM-related difficulties in the future, according to the company.

How To Disable Afm Without A Tune

There are cases where you need to get rid of the AFM momentarily, but can’t do so because of a lack of knowledge on how to do it. Some of us like to play with the AFM from time to time, and this includes figuring out how to turn it off without a tune-up.

Using An Afm Disabler

Using an AFM deactivator is the most efficient and straightforward method to deactivate the AFM. It is simple to install, simple to activate, and simple to uninstall. By removing the AFM from the OBD2 port, everything will return to its previous state when you need it.

Remove the Brake Booster Vacuum Sensor.

It is possible to turn off the AFM by removing the vacuum sensor from the brake booster assembly.

However, this is not a fail-safe strategy, as you may see the check engine light on your car’s dashboard.

You can, however, disable the AFM, and you should scan the vehicle on a regular basis to determine if your vehicle has a problem.

Final Thoughts – How to Prevent AFM Lifter Failure

The failure of an AFM lifter can be caused by a variety of different problems.

It is possible for an AFM lifter to fail due to a mechanical problem, which is the first problem to occur. This can be caused by something as basic as a damaged bearing or as complex as a faulty gearbox.

Failure of the materials used in the construction of an AFM elevator is the second problem that can cause it to fail. This will help prevent premature failure by ensuring that all materials have adequate performance levels.
