What is the EGR on a Honda Accord?
The EGR (Exhaust Gas Recirculation) valve helps lower the car’s exhaust emissions (gases from the tailpipe). It recirculates the portion of the gasses coming out of the engine by putting in back into the intake manifold, where the engine can burn it again, thereby reducing the emissions.
How do you clean a Honda EGR valve?

Wipe out the inside of the valve with a rag, making sure it is completely dry before reinstalling the valve. Place a new gasket on the intake’s mating surface.
What happens if EGR valve is blocked?
If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases. This may cause pinging (detonation), as well as surging on light acceleration. In a diesel engine, a bad EGR valve is one of the causes of a black smoke. The Check Engine light might also come on in either case.
Can you clean a dirty EGR valve?
To clean your EGR valve, start by cleaning the vacuum hose with carburetor cleaner or a pipe cleaner. Then, unbolt the valve, and clean the return tube and entry port using carburetor cleaner, and a toothbrush or pipe cleaner.
How does a Honda EGR valve work?
The EGR system works by returning a small portion of exhaust gas to the engine’s combustion chambers through the intake manifold, lowering combustion temperatures and therefore reducing the amount of NOx emitted. The EGR valve is the main component of the EGR system and it’s normally closed.
Does a 2000 Honda CR V have an EGR valve?
The 2000 Honda CR-V EGR valve is located on the intake manifold. … A faulty EGR valve can cause problems with the flow and operation of the EGR system leading to performance issues including a reduction in power, reduced acceleration, and decreased fuel efficiency.
What does this code mean P0404?
When P0404 is triggered, it means that the PCM has been told that the valve is performing in a way that is outside of its specified parameters. More specifically, the PCM has been told that the valve is closed when it should be open, or vice-versa.

How does EGR valve get clogged?
Causes of EGR valve clogging Both are susceptible to sticking or not seating properly due to a build-up of soot, carbon and even oil around the spool or valve seat. … When soot and carbon deposits build up around the valve seat, the valve is not able to fully close.
Can EGR cause limp mode?
A faulty EGR can result in excessive carbon/soot at the turbine end of the turbo charger. This could cause the VNT mechanism to become clogged and stick which in many cases will cause engine management lights to appears along with reduced performance known as “limp mode”.
How often does EGR valve need cleaning?
Every 50,000 or so miles, car manufacturers recommend that the EGR valve and different passages be cleaned. You don’t have to wait for this time before you start cleaning the valve.
Will a bad EGR valve cause rough idle?
An EGR valve that is stuck open can result in a fuel-air mixture that is too lean. This can cause a rough idle. A vacuum pump can be used to test whether the EGR valve is operating properly. A faulty EGR valve may also cause your Check Engine light to come on, in which case a code reader may reveal the culprit.
Will a bad EGR valve cause misfire?
A faulty EGR valve can cause a misfire all too often. It is usually caused by clogged passages inside your car’s intake. It will also diminish your vehicle’s power output. Oil vapors inside the engine increase carbon accumulation inside the exhaust gas recirculation valve, causing a stuck valve.
Will a bad EGR valve throw a code?
In modern cars plugged EGR or Stuck open EGR can throw a code. Stuck shout EGR may not cause any running problems but EGR FLOW is monitored the ECU with by either Maf,map,temp sensor or some feed back circuit then it will throw a code. but in older cars it may not throw code.
