i got a check light , and i took the car to Honda and they said my EGR valve is fucked up , whats an EGR valve ?

and how the hell it broke so fast , the car is only 3 years old !

 

EGR valve takes air from the exhaust manifold and pumps it back into the intake on a deceleration. it helps keep emissions down.

check the hard lines and the valve itself, its PRONE to getting completley clogged with carbon.

 

so uhmm how much to replace it ? just the part itself ........

thanks

 

the valve itself probably isnt bad
you need to clean the passages, trust me. 95% of the time the valve operates fine just needs to be cleaned.

 

do all the cars in the states have them ??

cuz where i live , we dont really care about emissions , thats why i have never heard about EGR valve, only this car i have now recently having problem with the EGR valve, pftt

 

no, only some do.

 

alright , thanks a lot Kamin

Very True.

Exhaust Gas Recirculation valve.......try getting some valvoline synthetic throttle body cleaner.......that happens all the time on new fords...for some reason the code is thrown, but its just stuck.....i just tell my customers to use that tb cleaner and they say it works!...probably what yours is doing since your car is new, i doubt you need a new one!
good luck!

 

aight thanks a bunch guys

 

btw...those ford customers i was talking about spray like 2 cans in there....you might wanna just try 1 or just 1/2 first!

you should really remove the valve and passages to clean it, use something like a wire brush or stiff bristled pipe cleaner. spraying something like carb cleaner just dislodges the stuff and can easily become lodged in the engine (like an intake valve).

 

EGR reduces oxides of nitrogen emissions (NOx) by recirculating exhaust gas back in the intake as previously stated, but it does that at part throttle load - not during decel. It's not the only way to reduce NOx, it's just one of them. NOx is produced by high cylinder pressures and temperatures which disappear when rolling off the throttle anyway.

Exhaust gas recirculated into the engine is largely inert, so it takes up some of the space otherwise occupied by AF mixture. Exhaust gas has less than 2% O2 as compared to 20.8% for fresh air, so it doesn't support combustion.

The engine must also be at or close to operating temp. It's never on at idle, it would stumble and miss if it did. EGRs that are stuck open do exactly that. Ones that have passages clogged can fail a smog check and/or light up the CEL, even if it has an EGR VPS.

Some systems look for a MAP loss when it commands the EGR to come on and the lack of MAP signal change will trigger the CEL. It's also not on at WOT, doesn't use any hp either, so I don't see the rationale for removing them for street use.
