If you drive or own a car, you’ve probably had the experience of the “Engine Power is Reduced” light coming on. This warning light can be extremely concerning to the driver because it frequently corresponds with a noticeable drop in engine performance.
In this article, we will examine the meaning of the “Engine Reduce Power” light, its causes, and the steps you can take to identify and resolve the issue whether you have an Avalanche, trailblazer, suburban, Silverado, or Tahoe.
What Does Engine Power is Reduced Mean?
Car owners need to recognize the meaning of lower engine power to understand the reasoning and idea. Your vehicle’s performance is frequently restricted, as the engine power reduced alert suggests. This mode is activated by the Powertrain Control Module (PCM) in the event of a system failure.
Sometimes, when the vehicle’s performance noticeably decreases, the light may blink on the dashboard. The message “engine power reduced” indicates that your car’s performance has been lowered to protect the engine. Additionally, the car is alerting you to the fact that it has entered fail-safe mode by the lit engine power light.
6 Reasons Behind “Engine Power is Reduced”:
This light can illuminate for several causes, all of which are reasons for concern. Using high-quality scan equipment will make it easier to identify the exact location of the problem after your car has been scanned.
1. A loose Clamp and Wire
The wires and connectors in your car are everywhere, providing power and enabling operation. A loose ground wire, or a loose clamp, in the electrical system can all cause a malfunction.
Usually, this is the most obvious and simple problem. On the other hand, if all the wires are in their proper places and there are no loose connections or broken wires, then you need to consult a professional mechanic.
2. Circuit Issues
The normal operation of the TAC (Throttle Actuator Control) system is impacted by damaged cables and poor connections. This condition may cause a car to experience several issues, like entering a mode with reduced engine power.
3. Low Battery Voltage
A low engine power alert is typically caused by the batteries running out of energy to keep the engine running. The engine cuts off immediately when the battery runs empty. But only if there’s still some charge remaining in the battery. then the engine will keep running till the last of the fuel runs out.
4. Failure of the Alternator
The engine shuts down when the alternator fails because there is not enough electric current. This can occur when the alternator isn’t producing enough amps.
5. Issues with PCM or Data Networks
Numerous computers, sometimes referred to as modules, are found in the majority of late-model cars and are connected via a data network. The car could enter into Reduced Engine Power mode if there is a disruption in the network or if the PCM is having problems.
6. Issues With The Emissions System
Strict emissions regulations must be met by modern autos. A malfunction in the vehicle’s emissions system may result in a flashing of the “Decreased Engine Power light” indicator. A defective EGR valve, a blocked air filter, or a damaged catalytic converter are common emissions system issues.

How To Fix “Reduced Engine Power” Warning?
After you’ve identified the issue, you should be worried about how to fix this issue. Here are possible solutions for how to reset Reduced Engine Power light:
1. Repair or Replace Faulty Components
If an engine or other system component is proven to be problematic, it may need to be replaced. The throttle body, sensors, alternator, battery, fuel pump, and other key components may be included.
2. Clogged or Dirty Components
A clogged fuel filter or air filter can cause the “Reduced Engine Power” signal to illuminate. Cleaning or replacing these components can frequently resolve the issue.
3. Clean the Air Filters
The air filter is located in a rectangular plastic box near the engine block on one side of the car, on the inside of the fender. You must first open the container in which the air filtering takes place. Remove the filter and position it in front of the light. If there is dust or dirt on the filter, tap it against a hard surface to remove it.
4. Clean the Airflow Sensor
To locate the sensor, start the car engine and open the hood. If the engine falters after a few of sharp taps, you have a filthy sensor within the automobile. Restart the engine after disconnecting the sensor. If the engine performs better without the sensor, the sensor is dirty.
To find the sensor, start the car engine and open the hood. If the engine has trouble or acts strangely after you tap it a few times, there’s a dirty sensor in the car. Restart the engine after disconnecting the sensor. If the engine runs better without the sensor, it means the sensor is dirty.
5. Check the Overheating Problems
Overheating Issues can prevent your vehicle from producing maximum power. A hot engine requires more cooling capacity. As a result, when temperatures exceed standard limits, the engine will run slower. Excessive heat can also cause early wear on crucial engine components. To avoid these issues, check sure your car’s radiator fan is working properly. Also, keep the coolant level full so that the water pump can do its work properly. Finally, look for any leaks around the engine block. Excess oil could be escaping through these little cracks.
Is It Safe To Drive With Reduced Engine Power Light On?
When the “Engine power is reduced” light illuminates on the dashboard, you can drive gently. However, doing so is not recommended. Towing your car to the nearest repair facility is recommended because driving at such low speeds can be risky. Not to mention that your vehicle is in a fail-safe mode because something is wrong, and pushing it any farther may result in severe damage.
With correct diagnosis and repair, it can be swiftly and easily resolved. If you see this warning light, take it seriously and have your vehicle evaluated by a skilled mechanic whether it’s Equinox, Impala, Malibu, or Camaro.
