If you’re a vehicle owner and you’ve ever experienced the “Reduced Engine Power” warning light on your dashboard, you know how frustrating it can be. This warning light is an indication that your vehicle’s engine is not functioning at full capacity, which can lead to reduced performance and other problems.
Fortunately, resetting the reduced engine power light is a relatively simple process that can be done by following a few basic steps. In this article, we’ll walk you through the steps to reset the reduced engine power light on your vehicle.
What is the Reduced Engine Power Light?
The Reduced Engine Power warning light is a common feature in modern vehicles equipped with an electronic throttle control system. This system controls the throttle opening electronically, replacing the traditional mechanical link between the gas pedal and the engine throttle.
The Reduced Engine Power warning light indicates that the engine is not receiving the proper amount of power and may be in a “limp mode” to prevent further damage. In limp mode, the vehicle’s performance is significantly reduced to protect the engine from further damage.
Causes of Reduced Engine Power
There are a variety of reasons why the Reduced Engine Power light may come on. Some of the most common causes include:
- Dirty or clogged air filter
- Failed throttle body
- Malfunctioning electronic throttle control system
- Issues with the fuel system
- Problems with the engine’s sensors or wiring
- Low oil pressure
How to Reset the Reduced Engine Power Light
Resetting the Reduced Engine Power light is a relatively simple process. However, before you begin, it’s important to identify and address the underlying cause of the problem. Otherwise, the light is likely to come back on again soon. Here are the steps to reset the Reduced Engine Power light:
Step 1: Turn off the vehicle’s engine
The first step is to turn off the vehicle’s engine and remove the key from the ignition. This will ensure that the electronic throttle control system is fully reset.

Step 2: Disconnect the battery
Disconnecting the battery is the next step. This will clear the memory of the electronic control module (ECM), which controls the throttle system. Locate the negative terminal of the battery and use a wrench or socket to loosen the clamp. Remove the negative cable from the battery and leave it disconnected for at least 15 minutes. This will give the ECM time to fully reset.
Step 3: Reconnect the battery
After 15 minutes, reconnect the negative cable to the battery and tighten the clamp with a wrench or socket. Make sure the cable is securely attached to the battery terminal.
Step 4: Start the engine
Start the engine and allow it to idle for a few minutes. The Reduced Engine Power warning light should be off at this point. If the light comes back on, there may be an underlying issue that needs to be addressed.
Step 5: Test drive the vehicle
Take the vehicle for a test drive to ensure that it’s running properly. If the Reduced Engine Power light does not come back on, you’ve successfully reset the system.
The Reduced Engine Power warning light can be a frustrating and confusing problem for vehicle owners. However, resetting the system is a simple process that can be done by following a few basic steps.
Remember, it’s important to address the underlying cause of the problem to prevent the light from coming back on again in the future. If you’re unsure about the cause of the problem or you’re uncomfortable performing the reset procedure yourself, it’s always best to seek the help of a qualified mechanic or technician.
