Since the check engine light is not on, we can be confident the ECU has not found any specific emission component failure.
How often does an exhaust gas recirculation ( EGR ) tube last?
The hoses can start to leak due to cracks over time, which then hinders the EGR valve’s ability to work properly. While there is no set lifespan for your exhaust gas recirculation tube, it is suggested you have an air induction procedure done approximately every 50,000 miles.
Can a faulty EGR valve cause your car to stall?
It may feel as though it is about to stall, it can stumble, and even shake. If you have tried to pass an emissions test recently, only to have your vehicle fail, that can be due to a faulty EGR valve. Once it is replaced, you should be able to pass the test. Your Check Engine Light may come on since the engine is not operating as it should.

How often should I Clean my EGR valve?
It is suggested that every 50,000 miles you have a carbon cleaning done, which is an air induction. This will clean out any carbons and sludge that is building in the air intake system and the engine. Once your EGR valve dies it will begin to affect your vehicle in a variety of ways, so it’s good to know what signs to watch out for.
What’s the best way to clean an EGR valve?
Cleaning the Valve: After removing the valve, use an EGR valve cleaner, if possible. However, you can use carburetor cleaner or solvent as well. Apply the cleaner to the passages at the bottom of the valve, intake and exhaust passages. Use a dull scraper and wire brush to remove carbon deposits from the bottom of the valve, plunger and valve seat.
Where is the EGR valve on a car?
The EGR valve is usually located around the top or backside of the engine, and to one side of the cylinder head, close to the intake manifold, or on the intake itself. Depending on your particular model, the EGR valve may connect to a pipe that goes to the exhaust manifold. But you won’t have much of a problem working with either type of valve.
Can a bad EGR valve cause system failure?
The EGR system includes several components like the EGR valve, hoses, sensors, control circuit, pipes, ports, and passages. Replacing a bad EGR valve without checking or cleaning these other components can lead to system failure. Exhaust gases are prone to clog passages with carbon deposits wherever they flow.
