Unhappy EGR VALVE

Check Engine light came on and I took your advice and went to Autozone where they told me that the code was EGR valve. I purchased one, came home, disconnected the battery and when I reconnected it the code was erased. Is it gone for good (wishful thinking) or will it pop on again? Can I clean an EGR valve or do I need to purchase a new one?

Thank you all for your help and information on an earlier post. Can you all tell I am new at this?

Not wise for an old man to start on a young mans hobby

Re: EGR VALVE

The code will pop back after driving the car, try to spray it with carb and choke cleaner and reset you OBD and try again, if not just replace it.

Exactly. He bought the EGR valve while at AutoZone but for some reason he unplugged the battery previous to the repair. Now the MIL has reset and is not illuminated anymore. His question is whether the light will return.

the answer is YES if the EGR system has a problem. The EGR code does not necessarily mean there is a EGR Valve issue. It could be the solenoid or plug lines.

Re: EGR VALVE

just seemed a no brainer, if the egr is throwing a code...and he bought a egr...next step would be to replace the egr correct? lol.

Just unplugging the battery will clear it until it trips it again. it will happen again so just change the egr valve.

you could also run some seafoam through the motor to help loosen up any buildup. but DO IT OUTSIDE do not do it in a enclosed space. It makes ALOT of smoke.

dump seafoam into intake tract, let it bog the motor some, poor a lil more til it bogs it down and dies. let it set for 5-10min and start it back up and watch the smoke pour out the exhaust. when it settles slightly run the car around the block so there is a load on the motor to help get rid of the rest.

No because the EGR code is NOT necessarily ONLY for the EGR valve. What P# code did you get? More than likely is for the EGR systems and is possibly a clogged valve, hose, or even a bad solenoid, Although I am not saying its NOT the valve just other possibilities. Its not a a good idea to start just changing parts.


I have guys coming in all the time at my Dealership with the Autozone said I needed Spark Plugs or 02 sensors because I had a misfire or 02 code. So, they changed all the parts in a guessing attempt running up a huge bill. When it could be running lean/rich need a coil or 2 or even have problems further up the line causing problems (PCM or other modules)

A true diagnosis is the only correct and cheaper way for most repairs IMO.

And YES Seafoam is great!

Re: EGR VALVE

I was under the assumption he had the code number and it was talking about the egr.

Re: EGR VALVE

EGR Valve = Exhaust Gas Recirculation Valve

I understand Bane, but just FYI, Even if he pulls a specific code for a specific problem you should always check all the options. I'm sure he appreciates the help you tried to provide!

Re: EGR VALVE

THEY're located on different points on different cars. its gonna be close to the intake manifold. itll have a pipe going into the exhaust as well.

Re: EGR VALVE

It should connect in the vicinity of the drivers side rear of the engine (if standing in front of the vehicle) on most vehicles. Has a tube that connects to the exhaust manifolds and the intakes
