Symptoms of a Bad EGR Valve (and Replacement Cost)

The purpose of an exhaust gas recirculation (EGR)
Valve is to improve your vehicle’s economy and performance.
Not only that, but it also cuts down on emissions
Because it allows exhaust gasses to flow back through the;
Cylinders to get burned again.

The EGR valve even cuts down the emissions of nitrous oxide and
It allows the warmer exhaust to flow into the engine once again.
As a result, the mixture of fuel and air won’t have to work.
So, hard to maintain the operating temperature of the engine.

So, what happens when you have a bad EGR valve?
Here are 3 of the most common signs of a faulty EGR valve.

3 Bad EGR Valve Symptoms

1. Check Engine Light.

If the “Check Engine” light on your vehicle’s dashboard turns on,
Your car’s computer is letting you know there is a problem with a specific part,
Or system in your vehicle. One possibility is a bad EGR valve.

Usually, the computer of the vehicle will be able to sense the position or circuit of the EGR valve. If it senses an issue with one of these,
The Check Engine light will illuminate and
Then the driver can use a diagnostic scanner or
Take it to a mechanic to confirm the issue.

Since an illuminated Check Engine light can indicate any of over a hundred issues,
A specific trouble code relating to the part will need to appear. Commonly, the trouble code for an EGR problem is P0400. Check various online resources to verify what the actual trouble code means.

2. Weak Engine Power.

If there is an EGR valve problem, the first symptom you’ll notice is a performance problem with the engine. If your EGR valve is malfunctioning or just clogged,
The air-to-fuel ratio of your vehicle will be disrupted.

This will cause all kinds of engine problems like a reduction in acceleration,
Fuel efficiency, and power.

3. Rough Engine Idle.

A common symptom that arises from a bad EGR valve in a vehicle is something called rough idle. When malfunctioning occurs with EGR valves,
They end up stalling in their open position. Then a rough idle will form from the
Recirculation of the exhaust gas, no matter if there are desirable conditions or not.

EGR Valve Replacement Cost

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. Of course, these costs estimates don’t factor in the fees and taxes
That will get added to the total as well.

When you get the replacement done,
The service should include an EGR transducer test,
Inspection of vacuum hoses connected to the EGR valve,
Clearing of all the trouble codes,
Cleaning of carbon deposits from the EGR pintle,
And a test of the EGR valve to ensure it operates smoothly.

EGR Valve Maintenance Tips

Every 50,000 miles (ca. 80,467 km),
You should have an air induction service done on your vehicle because
It will clean the carbon and sludge that accumulates in your vehicle’s air intake system. And, of course, get regular oil changes too,
Because it will reduce the chances of sludge accumulating in your engine.
