How to replace the EGR valve on 1998-2002 Honda Accord 2.3 I4 (F23a) # Make sure engine is completely cool! Remember, you are working on a portion of the engine that deals with the exhaust. # Disconnect the battery. Its not necessary but advised. # Looking at the engine from the front of the car, the EGR valve is directly behind the left back side of the valve cover. It is black and round on the top, about 1.5 inches in diameter. It will have an electrical connection plug coming out of the side of it. # Remove the electrical plug. # Looking straight down at the EGR valve, you will see the two 12mm bolts holding it to the manifold. # Remove the two 12mm bolts using a deep socket and extension on a 3/8" ratchet. Careful not to drop or loose the bolts! # The EGR valve should pull straight up and off at that point. # Since you have the EGR off, it would be a good idea to clean the ports using some type of aerosol cleaner( brake clean works) and a rag. # Make sure ALL of the old gasket is off the manifold and there is a nice clean surface to bolt the new EGR valve on to. # Line up the new gasket and install new valve by reversing the removal instructions. # If your check engine light was on, it should reset itself and stay off if you disconnected the positive battery terminal during your install. If you left the positive terminal hooked up, disconnect for several minutes to reset the ECU.
