What does a Ford EGR valve do?
The EGR valve, which stands for Exhaust Gas Recirculation, is a component of a vehicle’s exhaust system and engine health. It is used in both gasoline and diesel engines to control emissions. The EGR valve allows a small amount of exhaust gas to re-enter the intake system, changing the chemical composition of the returning air. This reduces the production of nitrogen oxides (NOx) and lowers the temperature in the combustion chamber, resulting in improved efficiency and air quality .
When the EGR valve fails, it can lead to various issues. Some common symptoms of a faulty EGR valve include knocking noises in the engine, reduced fuel economy, poor acceleration, rough idle, and a check-engine light illuminating. It is important to note that a faulty EGR valve can trigger the check-engine light, but it is always recommended to have the vehicle’s computer scanned for trouble codes to accurately diagnose the issue.
Overall, the EGR valve plays a crucial role in reducing emissions and improving engine performance by recirculating exhaust gas back into the combustion chamber .

What happens if your EGR valve gets stuck closed?
Whether the EGR valve is stuck in the open or closed position, this will impact the air-fuel balance, causing the engine to use more fuel than normal to achieve the same power output. You’ll feel this in a couple of places; first in the accelerator pedal, which will take more time to get up to speed.
Does removing EGR increase power?
Deleting the EGR system reduces carbon buildup and improves airflow to the engine. This will result in better performance. With an EGR delete, you may experience improved throttle response, increased horsepower, and greater fuel efficiency.
Does EGR increase power?
However, adding EGR to a diesel reduces the specific heat ratio of the combustion gases in the power stroke. This reduces the amount of power that can be extracted by the piston, thereby reducing the thermodynamic efficiency. EGR also tends to reduce the completeness of fuel combustion during the power stroke.
What is the most common causes of EGR failure?
However, the single biggest cause of failure is the buildup of carbon particles from the exhaust gases along the EGR and intake system passages. Over time this will clog tubes, exhaust gas channels and eventually the valve’s plunger mechanism, causing it to either stick open or close.
Is EGR delete bad for the engine?
Disadvantages of EGR Delete
While there are often many benefits to bypassing a flawed system, they may not be right for every vehicle. Some diesel vehicles can experience adverse effects like reduced horsepower, increased exhaust gas temperature and engine knocking.
What happens when the EGR valve goes bad?
A malfunctioning EGR valve can lead to a noticeable decline in engine performance. You may experience a rough idle, hesitation, or stalling when starting your vehicle. Acceleration may feel sluggish, or you may notice a lack of power when driving uphill. Increased fuel consumption.
Is it OK to drive without EGR valve?
Technically you can drive without a working EGR valve.
The role of your EGR valve is to reduce the number of toxic NOx gases in the air, so if it isn’t working quite right, more toxic gases will be released into the air. For this reason, we don’t recommend driving without a working EGR valve for too long.
Does removing the EGR valve damage the engine?
It reduces the NOx levels in the exhaust by recirculating some of the gasses back into the combustion chamber. While it is not bad as such to delete or blank an EGR in many places is is against the low as the engine will now produce more emissions that it was originally intended to.
What are the disadvantages of removing EGR valve?
Some diesel vehicles can experience adverse effects like reduced horsepower, increased exhaust gas temperature and engine knocking. In some cases, it can be more beneficial to have an EGR valve replaced, rather than bypassed.
How do I know if my EGR valve needs replacing?
Here are the 8 common signs of a failing EGR valve :
- Poor Mileage. Poor Mileage.
- Loss in Performance. Loss in Performance.
- Higher Emission. Excessive smoke from the tailpipe.
- Knocking Sound. Engine Knocking.
- Rough Engine Idling. Rough Engine idling.
- Smell of Fuel. Fuel smell.
- Engine stalls while idling.
- Check Engine Light ON.
