How much does it cost to fix reduced engine power? If you’re driving and suddenly see the reduced engine power or engine power reduced message on your vehicle’s display, it can be alarming. But don’t worry, there are a few potential reasons why this might happen, and it might not be as costly to fix as you think. Keep reading to learn more about what this message means and what you should do if you see it.
How Much Does it Cost to Fix an Engine With Reduced Power?
The cost to fix reduced engine power will depend on the severity of the problem, and can range from $100 to $700. In some cases, the problem may be a simple fix, such as replacing a dirty air filter. However, if the issue is more serious, such as a faulty sensor or fuel injector, the repair bill will be higher. If you’re experiencing reduced engine power, take your car to a mechanic for a diagnosis and estimate of the repairs.
Reduced Engine Power Warning Meaning
If you see a reduced engine power warning light, it means your car’s computer has detected a problem that could cause the engine to lose power. There are many potential causes of this warning, so it’s important to have the car checked by a mechanic as soon as possible.
Diagnosis Of Reduced Engine Power
There are many potential causes of reduced engine power, so it’s important to have the car checked by a mechanic as soon as possible. The mechanic will hook up a diagnostic tool to the car’s computer and run tests to determine the cause of the problem. Once the cause is determined, they will be able to give you an estimate of the repairs.
Causes Of Reduced Engine Power Warning And Fixing Them
Why your car goes into reduced engine power mode can be due to various issues. The following are the most common causes of reduced engine performance.
1. Loose Connection
All the important parts in your car are connected by wires. If there are loose ends or a particular wire is broken, the motor will activate failsafe mode. This problem can also occur if the ground wire is not securely fastened or the clip is loose.
Loose wires are easy to fix; although it may be difficult to find, you may need to run a full system check to detect it.
2. Defective Oxygen Sensor
The oxygen sensor is one of the most important parts of your car’s emission control system. It monitors the exhaust fumes and sends a signal to the computer to adjust the air-fuel mixture. If the oxygen sensor is defective, it can cause the engine to run lean or rich, which will trigger the reduced engine power warning.
Replacing it with a real oxygen sensor is an easy repair that can be done at home by a professional mechanic.
Vehicles typically have two oxygen sensors, one upstream and one downstream of the catalytic converter on the exhaust system duct. Due to expansion and contraction, the O2 sensor can get stuck in the pipe threads. You have to use a lot of torque to remove the sensor. For this you will need a long socket wrench.
Before removing the O2 sensor, check its harness connector first. After that, use the Bluedriver scan tool to diagnose the O2 sensor. There is a section on diagnosing a bad O2 sensor in my P0171 code guide.
The mechanical labor cost of removing the oxygen sensor and repairing the reduced engine performance depends on how difficult the oxygen sensor is to use. Typically, labor costs to replace an O2 sensor can be as high as $200. Oxygen sensors cost anywhere from $20 to $100.
2. Throttle Body Issues
The throttle body is a device that controls the amount of air that enters the engine. It’s located between the air filter and the intake manifold, and it consists of a throttle plate and a throttle body assembly. The throttle body assembly includes the throttle position sensor (TPS), idle air control (IAC) valve, and throttle actuator control (TAC) module.
If the throttle body is dirty, it can cause the engine to run lean or rich, which will trigger the reduced engine power warning. Cleaning the throttle body is a relatively easy repair that can be done at home. However, if the throttle body is damaged, it will need to be replaced, which is a more difficult and expensive repair.
3. Malfunctioning Ecu
The ecu is the brain of your car; it controls all the electronic systems in the vehicle. If the ecu is malfunctioning, it can cause the engine to run lean or rich, which will trigger the reduced engine power warning.
Replacing the ecu is a more difficult and expensive repair.
4. Failing Mass Airflow Sensor
The mass airflow sensor (MAF) is located between the air filter and the intake manifold. It measures the amount of air flowing into the engine and sends a signal to the ecu. If the MAF is dirty, it can cause the engine to run lean or rich, which will trigger the reduced engine power warning.
Cleaning the MAF is a relatively easy repair that can be done at home. However, if the MAF is damaged, it will need to be replaced, which is a more difficult and expensive repair.
5. Clogged Catalytic Converter
If your engine experiences reduced power, it is most likely due to an issue with the catalytic converter. The converter is a component of the exhaust system that helps to convert fumes into less harmful contaminants. If the converter becomes clogged or damaged, it can cause a decrease in engine power. In some cases, you may be able to clean or repair the converter to restore power. However, if the damage is severe, you may need to replace the converter.
6. Transmission Failure
If your car’s transmission is not working properly, it may not be able to shift gears correctly. This can cause the engine to work harder than it should, which can lead to reduced power.
If you think that your transmission may be the problem, the first thing you should do is check the fluid level. If the fluid is low, it may be causing the transmission to slip. You should also check for any leaks in the system. If you find a leak, it will need to be fixed before you can add more fluid.
How To Reset Reduced Engine Power Light
Once you have repaired the underlying problem, you will need to reset the reduced engine power light. The best way to do this is with a scan tool. Most autoparts stores will lend or rent you a scan tool for free.
If you don’t have access to a scan tool, you can disconnect the battery for 30 seconds to reset the light. Keep in mind that this will also reset all the other electronic systems in your car, so you may have to re-enter some settings.
You can also use a code reader to reset the light. Code readers are less expensive than scan tools and they are easy to use. However, they will only reset the check engine light, not the reduced engine power light.
1. Disconnect the negative battery cable.
2. Wait 30 seconds.
3. Reconnect the negative battery cable.
4. Start the car and check for any codes. If there are no codes, the light should be reset.
5. If the light is still on, take the car to a mechanic for further diagnosis.
Once you have repaired the underlying problem, you will need to reset the reduced engine power light. The best way to do this is with a scan tool. Most autoparts stores will lend or rent you a scan tool for free.

Is It Safe To Drive With Reduced Engine Power?
If your car is experiencing reduced engine power, it is not safe to drive. The reduced power can cause the engine to overheat, which can lead to engine damage. It can also cause the car to stall, which can be dangerous if you are driving on the highway. If your car stalls while you are driving, pull over to the side of the road and call a tow truck.

If the reduced engine power light comes on, you should take the car to a mechanic for further diagnosis. The mechanic will be able to determine the underlying cause and make the necessary repairs.
Will A Bad O2 Sensor Cause Reduced Engine Power?
Yes, a bad O2 sensor can cause reduced engine power. The O2 sensor is part of the emission control system, and it helps to regulate the air-fuel mixture. If the sensor is not working properly, it can cause the mixture to be too rich or too lean, which can lead to reduced power.
How Do I Get My Car To Stop Saying Engine Power Reduced?
If your car is saying engine power reduced, you will need to take it to a mechanic for further diagnosis. The mechanic will be able to determine the underlying cause and make the necessary repairs.
