Where is the EGR port on a Honda Accord?
Learn how to properly clean clogged EGR ports on a Honda Accord. This article applies to the Honda Accord (1990-2002). The EGR ports on an engine exist to release exhaust fumes into the intake manifold.
What’s the best way to clean the EGR port?
EGR port plugs installed. Cleaning the EGR valve is optional; however, it is best to clean out all the carbon deposits found on the manifold to avoid any future issues. Remove the two mounting nuts for the EGR. Flip the unit over and attach it to a vacuum pump. While its valve is open, spray some carb cleaner inside. Figure 10.
What’s the best way to clean a Honda Accord?
It’s best to wait overnight to allow the pressure in the fuel rail to settle. Open the gas tank to relieve any excess fuel pressure. Disconnect the vacuum and fuel line attached to the regulator at the end of the rail. Loosen the bolts on the FITV (fast idle thermal valve).

What to do if your EGR valve is stuck?
Remove and clean, or replace, the plugged up tube that FEEDS the EGR valve. If this is the same code as before it sounds like either a clogged EGR passage or a stuck EGR valve. The entire passage way needs to be checked out for clogs.
What to do if your EGR valve is clogged?
If your EGR valve is clogged, you don’t necessarily have to replace the valve. It is possible to remove the EGR valve from your Honda’s engine and clean all of the carbon deposits from the valve. Cleaning your EGR valve should make your Honda idle more smoothly.
Where is the EGR valve located on a Honda?
The valve location will vary between vehicles. It is toward the front of the engine on the driver’s side for most Hondas. The owner’s manual will have a diagram to help you find the exact location of the EGR valve. Remove the EGR valve from the engine.
How do you replace an EGR water line?
Let it soak in the cleaner for at least 8 hours. Use a wire brush to remove any visible deposits left on the EGR valve. After soaking in the cleaner, any deposits should brush right off. Replace the EGR valve. Put it back exactly as you found it, hook the wires and hoses back up and bolt the valve back into place.
What happens when the EGR port is clogged?
The EGR ports on an engine exist to release exhaust fumes into the intake manifold. When the ports become clogged, the engine can experience several different problems including stalling, bogging, poor fuel economy and hesitant acceleration.
Why do I need to clean the EGR port on my Honda Accord?
Over time, the EGR ports on an intake manifold will become clogged with carbon deposits. The ports will need to be cleaned in order for the car to run correctly.
What does DTC p1491 stand for in Honda?
If this happens, the vehicle may hesitate or surge during light acceleration, and the MIL (malfunction indicator lamp)may come on with DTC P0401 (EGR insufficient flow) or P1491 (EGR valve insufficient lift). If DTC P0401 or P1491 is stored, or if the engine hesitate or surges, clean the EGR port, install an EGR pipe kit, and clear the code.
Can a vacuum cleaner be attached to an EGR port?
Vacuum cleaner attached to the EGR port. Check and make sure the ports are fully cleaned. When they are clean, carefully use a sledge hammer with a small rod to hold them steady and knock in the new plugs. The plugs should sit flush on the intake. Figure 8. Cleaned EGR port. Figure 9. EGR port plugs installed.

What to do if there is no wire in an EGR valve?
If there is no wire, continue. Spray the inside of the EGR valve with carburetor cleaner, then shake the EGR valve out. Carefully scrape stubborn soot off with a screwdriver. Wipe out the inside of the valve with a rag, making sure it is completely dry before reinstalling the valve.

What should I do if my EGR valve is not working?
If the stem or diaphragm doesn’t move, disconnect the thin vacuum hose from the top of the valve. Place your finger on the opening of the vacuum hose you just disconnected. Increase engine rpm again as you did in the previous step. You should feel vacuum or a slight pressure on your finger tip, depending on the particular system type.

What kind of valve does a Honda Accord use?
We offer a full selection of genuine Honda Accord EGR Valves, engineered specifically to restore factory performance. Please narrow the Emissions EGR Valve results by selecting the vehicle.
How does an EGR valve work in a Honda?
In a Honda, the EGR valve will have one electrical connection to the engine and may also have 1 to 2 hoses attached. These connections will likely be held with retainer clips that will just need to be pressed to release the plug. Hoses may be held in place with screws. The valve will also be bolted in with 1 or 2 bolts.
Why is the EGR valve open at part throttle?
At part throttle, there is a vacuum in the intake manifold. Also the exhaust gas is at positve pressure. So when the EGR valve opens, exhaust gas is easily drawn into the intake manifold. Running EGR allows you to run more timing at light cruise loading.
What should I do if my EGR port is clogged?
Each port should be filled with what looks like a black gunk, also known as carbon buildup. The first thing to do is to remove the old EGR port plugs. Drill into the plugs. Thread them using a 10-24 tap. Use the slide hammer to break lose the plugs on the intake manifold. Remove each plug. Figure 4. Clogged ports. Figure 5.
