“Reduced Engine Power” is a common warning from your Chevrolet Malibu. This message displays on your dashboard when a sensor reads that the power is reduced.

It can be challenging to fix, so make sure you follow the correct procedures for your particular vehicle model. To diagnose the problem, look at the vehicle’s TSBs and codes to determine the specific cause. If you have a new car, it may be worth your time to look up the TSBs for the specific model year.

One of the most common causes of reduced Chevy Malibu engine power is a malfunctioning accelerator pedal position sensor.

The MAP sensor measures the density of the air entering the Malibu engine. It can fail, resulting in reduced engine power. Another possible cause of reduced engine power in the Chevy Malibu is a dirty throttle body.

If the throttle body is dirty, it will cause a temporary drop in engine RPMs below idle speed. The PCM will compensate for this temporary loss in engine power and reduce fuel economy.

Some people have reported that their Chevrolet Malibu’s engine power is reduced suddenly. They may experience a warning “Engine Power Reduced” on the dashboard.

During one instance, a man named Mark Rothschild bought a new 2017 Chevy Malibu and noticed that it suddenly lost power.

When he noticed this in March 2018, he steered the vehicle to a safe location out of traffic, despite the fact that he feared for his safety.

Some of the other common causes of reduced Chevy Malibu engine power include a faulty fuel pump. The fuel pump is an important component that builds pressure in order to start the car.

A bad Mass Airflow Sensor can also result in reduced engine power. If your Malibu is exhibiting any of these symptoms, it’s best to have it checked by a professional mechanic. It can cost as much as $100 or more.

Another common cause of reduced chevy malibu engine performance is a damaged air filter. This filter filters out dust particles in the cabin air.

A dirty air filter can reduce engine power, increase fuel consumption, and increase the risk of engine failure. To ensure optimal engine performance, replace your air filter before the problem worsens.

It’s worth the time and effort to inspect and replace this part, and it’s guaranteed to make a difference in your vehicle’s performance.

Another common cause is a faulty electronic control unit. This component can be repaired or replaced, but this process is costly and can cost as much as $2,000.

Lastly, a damaged battery is another common cause of reduced engine power. A battery needs to be checked for corrosion and loose connections, but it’s best to replace the entire unit if it is damaged. So, check your car’s tyre pressure and battery condition to ensure the problem is not serious.


If you own a 2018 Chevrolet Malibu, the issue of reduced engine power is an increasingly common problem. Although no definite fixes have been released, it has been observed that GM has replaced faulty accelerator pedal position sensors with unimproved versions.

That is, GM has adopted a “band-aid” approach that could have long-term negative consequences. However, a class action lawsuit has been filed against the company.

If you’re unable to diagnose the cause of your car’s Engine Power Reduced warning, the best thing you can do is to check the TSB. The TSBs for your car are extremely detailed and contain repair instructions and codes.

Following these instructions carefully can make the difference between a malfunctioning engine and an unresponsive car. It’s important to follow these instructions to make sure that your Malibu is running at optimum performance.

Another cause of the Reduced Engine Power warning on a Chevy Malibu is a malfunction in the fuel system. The reduced engine power warning can occur for a number of reasons.

Either the engine is undergoing a repair or the car’s fuel system is having an issue, but it should be running at a reduced power level anyway. However, if this message persists and you still want to drive your car normally, you should try to find a repair shop.

Another possible cause for the reduced engine power warning is a malfunction in the accelerator pedal position sensor. In such a situation, you can replace the throttle body or even the entire fuel pump.

Changing the throttle plate is more efficient than replacing individual parts. Depending on the cause of the reduced engine power light, replacing these components can cost anywhere from $100 to $500. This repair will vary in cost, but can often solve the problem.

If you experience reduced engine power on your Malibu, it’s important to address the problem as soon as possible. This problem could result in a sluggish engine and the need to depress the accelerator pedal further.

If you suspect a malfunction, you should immediately contact a mechanic or a repair shop. If the problem is a more serious issue, call a towing service.

If you own a Chevy Malibu, you’ve probably seen the “engine power reduced” warning. It’s a serious warning sign because it means your car’s performance is suffering.

The main computer in your car, known as the powertrain control module, will turn the reduced power mode on when there’s an issue with the car’s engine. To find out more about this warning, check your car’s owner’s manual.

A faulty accelerator pedal position sensor is one common cause of the “engine power reduced” warning message on your Chevy Malibu. This sensor helps translate the pedal pressure into a signal that your car’s engine needs to start.

Sometimes, this sensor does not work, and the engine is left to run without getting the fuel it needs. To resolve this problem, you need to take your car to a mechanic immediately.

A damaged throttle body can also be the cause of a reduced engine power warning. The butterfly valve opens and closes the throttle and a malfunction in this part will make it difficult for your car to receive air.

The butterfly valve can also be clogged with carbon, which will make it believe less air is being pumped into the engine.

Replacing the throttle body is easier and cheaper than replacing individual parts, but it can cost as much as $200, not including labor.

Another issue that can cause the engine power reduced warning is a faulty transmission. These problems can be difficult to identify, but a good mechanic will have the ability to locate the problem and fix it.

A faulty transmission will also trip the check engine light. If the transmission is failing, you need to replace the entire transmission. This issue is one of the most common and expensive. Your mechanic will use a scanner to find the fault and fix it.

An error in the PCM may also cause the “engine power reduced” warning light to show up while driving. In addition, a faulty PCM could affect the fuel supply to your engine.

The engine power reduced mode is a failsafe strategy built into modern cars to protect the driver against such an occurrence. So, how can you fix your Chevy Malibu’s engine power problem?

There are several parts of your Malibu that could be causing this problem. First, check the air filter. A clogged air filter will not cause the error code, but it will cause your engine to operate at reduced power.

Check the following components to ensure your vehicle is running at optimal power. If you find any of them malfunctioning, replace them immediately. If you can’t fix it, you might want to consider a Chevy Malibu engine power reduced repair.

The problem itself could be caused by a damaged catalytic converter or a faulty electronic control unit. Either way, replacing these parts will cost between $100 and $160.

Another common cause of the engine power reduction problem is a dirty throttle body or a malfunctioning throttle body.

Fortunately, replacing the entire throttle body and position sensor is much easier than replacing individual parts. However, it’s important to note that a Chevy Malibu engine power reduced error may require you to replace some expensive parts.
