How To Bypass Reduced Engine Power: Everything You Need To Know

Imagine you were driving your car, a message arrives on your car’s dashboard saying “Engine Power Is Reduced”. What would you do?

You notice your car is steadily slowing down. You might try to accelerate to fix this problem but it resulted in your car completely shutting down. We call this sort of problem “Reduced Engine Power”.

Engine power reduction can be a frustrating and risky issue to handle, especially when it occurs while you are in the middle of a road. So, you need to know how to bypass reduced Engine Power.

We just need your patience. With that, we can show you how you can bypass reduced engine power in your car.

What does Reduced Engine Power mean

If you see an “Engine Power Is Reduced” message on the dashboard of your car, then consider that your vehicle cannot operate to its full potential.

If your car’s supercharger or turbocharger has fallen down or if the EGR (Exhaust Gas Recirculation) system has been clogged with carbon retainer or the fuel injectors are out of order or the oxygen sensor is out of order or there is an issue with combustion wiring. 

The message might come if you drive your vehicle for too long with an engine that also has been overheating for too long. Your car might run at reduced power while the message is exhibited.

A Step-by-step guide to bypass reduced engine power

Bypassing the reduced engine power is a simple procedure. Just follow through with the steps we’ll be showing you how to make it work

Checking the Catalytic Converter

You know when you experience reduced engine power in your car, the first thing you need to check is your catalytic converter. The OBD (On-Board Diagnostics) monitors will reduce the engine’s potential power to recompense for the problem that was caused by the catalytic converter.

You have to bypass the reduced engine power by replacing the catalytic converter. Although it would seem an unnecessary and expensive purchase, it is worth it to spend the money here.

Cleaning the Air Filter

Your car’s air consumption is the one to blame for drawing in oxygen, which will be used by the engine to burn the fuel. But if the oil building up on the spigots is compromised, then the oxygen can no longer enter the combustion chamber and it will lead to a reduction in the engine’s power.

So, you need to clean up the engine’s intake manifold. Just open it and brush off all the dirt and dust from it before the valves are compromised.

Checking the Engine Control Unit

You might be aware that the ECU system is running through a lot of sensors and displays that help your car distribute the power in the best way possible. But it’s going to be a hassle if one of those sensors is compromised. Hence, a reduction in the engine’s power will occur.

Now, you need to bypass the reduced engine’s power here to fix the problem. How will you do it?

Simply update the ECU’s firmware and software or just replace the entire ECU system with a new one.

Checking Sensors

When you experience a reduction in your engine’s power, you should always check the sensors. It’s the most crucial thing to do when you are in a pinch with reduced engine power.

The ECU alters power according to the information it gets from the oxygen sensors, mass air flow sensors, and intake manifold sensors. If one of these sensors falls down, it will send incorrect readings to the ECU which will cause issues for the engine.

You can’t fix it if one of the sensors falls down, you can try cleaning them but we’re afraid it doesn’t work most of the time. You need to replace the defective sensors with new ones.

Repairing the Exhaust Leaks

One of the reasons for experiencing a reduction in the engine’s power is exhaust leaks. A car normally creates high-pressure while driving. The Exhaust System is designated to take control and release the excessive pressure out of the car so that your car can run accurately.

Sometimes, there might be some holes in the exhaust system’s hose because of rust. It will release a desynchronized amount of pressure which will lead to a reduction in the engine’s power.

You have to search your system for any kind of leaks with a soap and water solution. Once you find them, replace the hose with a new one to bypass the reduced engine power.

How much does it cost to fix Reduced Engine Power

The first measure the mechanic would be taking is determining what’s been wrong with your engine. Typically, it would take about half an hour.

You have to pay for the replacements and the labor. So, the amount would be near 100 US dollars to 500 US dollars. The cost of the catalytic converter is excluded here. You need to pay 2,000 US dollars more to get a new catalytic converter.

If you’ve insurance for your car, then the insurance would cover the cost. But if you don’t have that, prepare to spend 2,100 US dollars to 2,500 US dollars.

Final Words

It’s time to wrap things up. But first, let us clear a misconception about the reduced engine power and the battery. 

Most people ask this question: Can a bad battery cause reduced Engine Power?

The misconception is that they think it does damage your engine and reduce the engine’s power. But a bad battery has nothing to do with it and it won’t cause a reduction in the engine’s power.

Now, you know all the necessary things you need to know regarding how to bypass reduced engine power, thus, we’ll be taking our leave here.
