Your best bet would be to check your catilytic converter, thats the thing in your exhaust system under the car that looks like a muffer, it could be clogged, triggering the Exhaust Gas Recirculation (EGR) fault code. However, I don't trust those scanners from these autoPARTS stores have a proffessional diagnosis done you will save money and headaches later. You probably have more than one trouble code. As for the fuel pump you will know when it goes bad, the vehicle will stop running period, so, don't change that.

Hello and welcome to FixYa!

Looks like that the EGR valve reached it's break point. As a first course of action, I strongly suggest that you replace it. This issue is common and you'll be good after the replacement.

2006 Dodge Caravan Sputtering. Code says EGR Valve. Would an EGR valve cause the van to sputter and run rough?

Absolutely. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on acceleration.

Try cleaning the EGR valve first

electronic Tempture Control
ECT sensor
Potential Symptoms

Symptoms of a P0118 could include:

* Very poor fuel economy
* A no start condition
* Vehicle may start, but run very poorly, blowing black smoke, running very rough and misfiring
* Illumination of MIL
EGR valve

Usually a fault in the control circuit, will leave no noticeable symptoms other than the Malfunction Indicator Lamp (MIL) illumination. However, if the EGR control solenoid
is stuck open due to debris, etc. the code may be accompanied by misfire under acceleration, rough idle, or engine dying altogether.

sounds like a problem in the egr valve or the porting through the egr valve or maybe a vaccuum line that has something to do with monitoring it. make sure there are no vacuum lines near it that are leaking and is there a difference in the idle that you may notice.
