What damage can a faulty EGR valve cause?
A damaged EGR valve is most likely to cause your vehicle's engine to begin to use up a lot of fuel than normal. For instance, your vehicle is normally on an average fuel economy of 25 miles per gallon or 10 liters per 90 kilometers. via
What happens when EGR is blocked?
If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might also come on in either case. via
How much is an EGR valve for a Dodge Ram 1500?

Will a bad EGR valve cause a check engine light?
If the EGR valve fails, the computer will recognize the problem and turn on the check engine light. This part may seem a little pricey, but it's typically an easy fix and will ensure that your engine gets back to running the way it should. via
How much does it cost to fix EGR valve?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle's year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80. via
Can you drive with EGR valve disconnected?
Yes it might affect the environment but no harm to engine as such. there are people who are running without EGR for more than 50k km. Also in all remapping they disable the EGR. There are some doubts on temperature increase in cylinder if EGR is disabled. via
Can you fix a stuck EGR valve?
Luckily, fixing the EGR valve is easy enough. EGR valves either become stuck in the open position or stuck in the closed position, so once you've figured out which problem plagues your own truck, you can get on with the rest. via
Can a blocked EGR cause limp mode?
A faulty EGR valve can result in excessive carbon/soot at the turbine end of the turbo charger. This could cause the VNT mechanism to become clogged and stick which in many cases will cause engine management lights to appears along with reduced performance known as “limp mode”. via
Where do you spray EGR cleaner?
Spray the product for 2 seconds into the air intake manifold but DO NOT SPRAY DIRECTLY INTO THE INTERCOOLER. After each spray, wait until the idle rpm is restored and engine runs stable. Repeat the process until all of the product has been discharged from the aerosol. via
How do you clean a clogged EGR valve? (video)
Is it better to clean or replace EGR valve?
Proper maintenance of the valve is a must if you want to avoid any performance related issues on your car. If you notice a smell of fuel that comes out from under the hood or rough idling, then it might be time to replace the valve. In most cases, though, you do not need to toss it out just yet. via
How long does it take to replace EGR valve?
How long does an EGR valve replacement take? Looking once again at the averages delivered by our data, an EGR valve replacement should take around 3/4 of an hour. Take a look at a few of our findings; you'll see some comparable times for how long the job can take for different makes and models. via
Can an EGR valve be cleaned? (video)
How do you clean an EGR valve without removing it? (video)
Can I use throttle body cleaner on EGR valve?
A good dousing with throttle body cleaner may be enough to restore your EGR valve to near-mint condition, transforming a harsh idle into a soothing hum. via
Does the EGR valve affect gas mileage?
The EGR valve cycles open and closed based on throttle movement and intake manifold vacuum to reduce exhaust emissions. If it sticks open due to carbon deposits and heat distortion, it creates a vacuum leak and rough operation. This will adversely affect fuel economy. via
Would a bad EGR valve throw a code?
Question: If I have a bad EGR valve, will it throw a code for a misfire in cylinder number 2? Answer: A bad valve most likely will cause a random misfire since it doesn't direct exhaust gases to a particular cylinder. via
How does EGR affect idle?
When the EGR valve is clogged or dirty, as they are prone to, it may not function properly causing the engine idle rough, stall at idle speeds, cause the car to get poor fuel mileage, emit a strong smell of fuel due to excess hydrocarbons which also results in failing emissions tests. via
Which of the following problems can be caused by an EGR valve that is stuck open?
Check engine light: as with most engine management components, a problem with the EGR valve may trigger the check engine light. Engine performance issues: if the valve is stuck open the vehicle's air-fuel ratio will be disrupted causing engine performance issues such as reduced power, poor acceleration and rough idle. via
What is the code for EGR valve?
P0401 is an OBD-II generic code that the engine control module (ECM) detected the engine exhaust gas recirculation (EGR) valve is not flowing enough recirculated exhaust gases when it is commanded to open the flow of gases into the intake manifold. via
How do you test a EGR valve? (video)
Can you drive with P0401 code?
Hi There, Code P0401 relates to the EGR valve flow. When this code is triggered, the computer has detected that the flow is insufficient. Driving the car until next week will not cause any harm, although the vehicle may not run well. via
What happens if you remove vacuum from EGR valve?
The disconnection of an EGR vacuum hose affects the efficiency and stability of the engine. When it leaks, it can make the EGR valve not open, increase the emission of harmful gases and also cause overheating in the engine. via
How do you test a EGR valve without a vacuum pump? (video)
Does EGR affect boost?
The coupling between EGR, the Variable Geometry Turbocharger (VGT) and the EGR cooler critically affects boost pressure, air/fuel ratio (A/F), combustion efficiency and pumping work. via
How do you test a EGR valve solenoid? (video)
What product can I use to clean a EGR valve? (video)
Which of the following are symptoms of a clogged EGR passage?
Always check the manufacturer's specifications for special procedures. The symptoms of a stuck open EGR valve are stalling, surging, and a rough idle. This stumble is noticeable. A stuck closed or restricted EGR valve results in high cylinder temperatures, detonation, and ping. via
Can a EGR valve cause a misfire?
EGR valve can cause a misfire
A faulty EGR valve can cause a misfire all too often. It is usually caused by clogged passages inside your car's intake. It will also diminish your vehicle's power output. via
Where is the EGR valve located?
The EGR valve is usually located near or attached to the intake manifold, with a tube running to the exhaust manifold. There should also be a vacuum or electrical connector (or both) running to the valve which will need to be detached. via
How do you prevent EGR valve failure?
Moreover, many EGR problems can be avoided by simply ensuring that the vehicle is maintained regularly and gets a decent blat down a highway at least once a month, with plenty of accelerating and decelerating (pottering around town at low speeds is especially bad for EGR valves). via
