How to Replace an EGR Valve On a 2001 Honda Odyssey

The Exhaust Gas Recirculation (EGR) valve, as the name implies, recirculates some of the exhaust gases that are emitted from your Honda Odyssey. The EGR valve cools down the gases and runs them through the engine a second time. This allows greater fuel efficiency and helps reduce emissions. If your Odyssey is idling rough or does not accelerate as it should, an EGR valve could be causing the problem.

Instructions

1

Disconnect the negative battery cable from the battery terminal. Make sure that the cable connector cannot touch metal to prevent accidental electrical shorts in the Odyssey.

2

Locate the EGR valve. Look for the vehicle vacuum schematic on the underside of the hood or consult an Odyssey repair manual. Usually, the vacuum wires are green; however, if an aftermarket hose has been installed, this may not be the case. Assuming that you are working with the original equipment, follow the green hose to the EGR valve.

3

Remove the vacuum hose and unclip the electrical connectors from the EGR valve. Remove the bolts holding the EGR valve to the exhaust manifold. These likely will be 10 mm bolts, but they could be 12 mm if theyve been replaced with aftermarket parts. Use a ratchet with an extension to remove the bolts.

4

Unbolt the EGR valve piece from the exhaust manifold tube that delivers the gas back into the combustion system. You will need a large crescent wrench for this step. If the bolt sticks or is rusty -- and only if the engine is cold -- use a few bursts of PB Blaster spray penetrating lubricant on the bolt and give it a few taps with the wrench. This will allow the spray to work into the threads of the bolt.

5

Examine the area from which you removed the old valve for carbon deposits. Use a generous amount of Carb Cleaner and scrape the deposits off with a small brush. Inspect the gasket for wear, carbon deposits or cracks. If the replacement EGR valve you bought was an OEM product, a new replacement gasket should be included.

6

Install the new gasket and EGR valve. Reconnect all the parts in the reverse order that you removed them. You may want to spray some anti-seize lubricant on the bolts as you reinstall them. This will make removing the bolts in the future an easier task.

Reconnect the negative battery cable to the battery terminal. Then, drive your Honda Odyssey a short distance. If you are still experiencing the same issues, you may need to replace the exhaust manifold or clean out the carbon deposits.
