As a Chevy Malibu 2016 through 2018 driver, there’s a chance you’ve, at some point, seen a notice that read “Engine Power is reduced”. Even traveling at highway speeds is said to cause rapid power loss in the vehicle and a 20-mile-per-hour slowdown.
It can be a little alarming when the check engine light on your car illuminates and you observe a decline in the vehicle’s performance. Unfortunately, you have no idea what it signifies and is unsure how to proceed.
Due to the risky nature of the issue, and since it prevents drivers from accelerating to a comfortable pace, many Chevy Malibu owners have expressed serious concern about it.
What Does Engine Power is Reduced Mean on a Chevy Malibu?
The “Engine Power is reduced” warning message, flashing on the dashboard of your motor or the device panel, usually means that your vehicle’s performance has been purposefully constrained. Lowered Power Mode is initiated when your car’s central computer detects a system malfunction, and this central computer is also called the power train control module (PCM).
The flash may occasionally come on if the PCM notices a significant drop in the vehicle’s operation due to an underlying issue.
The Engine Power is reduced Mode can limit your car’s performance and acceleration. In addition, because the Power train control module has stopped supplying fuel to the engine, the car may occasionally become impossible to drive.
Various factors could cause the “Engine Power is reduced” warning. A faulty accelerator pedal position sensor, a component of the electronic throttle actuator control (TAC) system, is the cause of the problem in the class-action lawsuits targeting Chevy Malibu models.

What Are the Signs of Engine Power is Reduced on a Chevy Malibu?
If you suspect a reduction in engine power in your automobile, here are symptoms and signals you may watch out for, even if the ERP light doesn’t illuminate. They are:
- Your vehicle moves more slowly.
- Needing to depress the accelerator pedal deeper to obtain a normal result.
- Your fuel efficiency drops.
- Your emissions are higher than typical.
If you notice any warning signs or symptoms, take your vehicle to a repair shop immediately. These issues will be identified, and repairs carried out immediately.
What Causes the Engine Power is Reduced Message on the Chevy Malibu?
The accelerator pedal is where the Chevy Malibu Accelerator Pedal Position Sensor is situated. The tiny, black sensor in charge of keeping track of the pedal’s position is inconspicuous. Its failure can lead to various issues, including a car’s decreased engine power.
The more recent Malibu models have what is known as a “drive-by-wire” system, in contrast to prior vehicles that used a cable accelerator system. This indicates that the accelerator pedal and throttle body are not physically connected.
The sensor keeps track of the pedal’s location and communicates that data to the car’s computers. Instructions from the computer then go to the engine’s throttle body to tell the power quality to supply.
An incorrect computer may transmit an incorrect message to the throttle body if the sensor isn’t functioning properly. Due to this, the engine’s power may be insufficient, which would reduce engine performance.
It’s possible that you can solve the issue on your own in some circumstances. For example, it might be possible to adjust or replace the position of the accelerator pedal sensor if it is broken or faulty.
Before doing any repairs, it is, however, always advised to seek professional advice.
The “Engine Power is Reduced” warning on the Chevy Malibu you own could also come up. When you see any of the error codes, it’s important to take your car to a mechanic as soon as possible. They can run a diagnostic test and make the necessary repairs.
Some other causes of this issue are as follows:
1. Throttle Body problems
When you talk about the throttle body, it regulates how much air gets into the engine. Therefore, engine power may be reduced if it is soiled or damaged.
2. Faulty Spark Plugs
The engine ignites the air and fuel combination using spark plugs. Therefore, engine power may be decreased, if they are harmed or fouled.
3. Engine Misfire
When a single or various engine cylinders ignite improperly, it is known as an engine misfire. Engine power may be reduced as a result of this.
4. Faulty Mas Airflow Sensor
A mass airflow sensor determines how much air is blown into the engine. Therefore, engine power may be decreased if it isn’t functioning properly.

What Are the Common Effects of Engine Power is Reduced on the Chevy Malibu?
Your car may be significantly affected if the engine’s power is reduced. To begin with, it may make it more difficult for your car to accelerate. This could be hazardous if you’re attempting to overtake a car or merge onto a highway.
Your fuel economy may suffer as a result, which is another drawback. It takes more effort for your car to retain an exact speed if it doesn’t have enough power. This implies it consumes more fuel, increasing the expenses on gas.
Intensified emissions may similarly result from a decrease in engine power. Your car can begin to emit more pollution if it doesn’t have adequate power.
Error Codes That Accompany the “Engine Power is Reduced” Message on a Chevy Malibu?
A code that signifies an error can be displayed along with the “Engine Power is Reduced” message. You can use these codes to deduce the issue and carry out the required fixes. The most typical codes include:
- P0221 – Throttle/Pedal Position Sensor(PPS)/Switch D Circuit Range Performance
- P0123 – Throttle/Pedal Position Sensor(PPS)/Switch A Circuit High Input
- P0223 – Throttle/Pedal Position Sensor(PPS)/Switch B Circuit High Input
- P0220 – Throttle/Pedal Position Sensor(PPS)/Switch D Circuit
- P0222 – Throttle/Pedal Position Sensor(PPS)/Switch B Circuit Low Input
- P0121 – Throttle/Pedal Position Sensor(PPS)/Switch A Circuit Range/Performance Problem
Getting your automobile serviced, immediately after you notice these codes is critical. A diagnostic examination will be done, and necessary fixes will be carried out.
How to Fix Engine Power is Reduced in a Chevy Malibu?
If you follow these procedures, you will be capable of solving the issue quickly, except for a very complicated one.
- Check the Cables
