Engine and emissions fitment
There is no single Civic EGR valve. Fitment changes with the generation, engine, transmission and whether the car was built to Federal or California emissions. The 1997-2000 cars came as coupe, sedan and hatchback with several engines. The 2001-2005 cars use engine-specific electronic valves, and a common 1.7L setup uses a 5-pin connector. The 2006-2011 cars split by engine, so a 1.8L valve should not go on an Si or Hybrid.
Fitment samples here include DX, HX, EX, LX, GX and Value Package trims. Compare the mounting holes, valve position, connector and pin count with your old valve.
P0401 and other warning signs
A failing EGR valve can cause a check engine light, rough idle, hesitation, stumbling, stalling, weak power, poor fuel economy, misfires or a failed emissions test. The most common code is P0401, EGR flow insufficient.
On 1996-2000 Civics, and often on 2001-2005 1.7L cars, P0401 comes from carbon clogging the EGR passages in the intake manifold, not from the valve. Cleaning those passages may fix the code. Check the passages, the EGR solenoid, the connector and any vacuum hoses before you buy a new valve.
Fitting the new valve
Check whether the listing includes a gasket. Honda sells EGR gaskets separately, and you should always fit a new one. Standard Motor Products lists several EGR valves for the Civic here.
On 2001-2005 cars the valve is held by two 12mm nuts. Unplug it, remove the nuts and lift it off. Before you install the new valve, scrape and clean the carbon from the manifold port so it can flow. Fit the new gasket, tighten the nuts evenly and plug in the connector. Clear the code and drive the car to confirm it does not return.

Civic questions
Will a new EGR valve fix P0401 on my Civic?
Not always. On many 1996-2005 Civics, P0401 comes from carbon blocking the EGR passages in the intake manifold. Clean the passages and test the valve before replacing it.
Does the Civic EGR valve come with a gasket?
Some listings include one and some do not. Honda sells the gasket separately, so check the product details and order one if needed. Always use a new gasket.
Does a 1.8L Civic EGR valve fit the Civic Si?
No. On 2006-2011 Civics, the EGR valve varies by engine, and a 1.8L valve should not be assumed to fit the Si or Hybrid. Check your engine in the fitment table.
