Where is the EGR valve located on a Dodge Caravan?
Use the hood release lever inside the Caravan to pop open the hood. Find the EGR valve, which is located on the engine intake manifold.
What are the effects of a bad EGR valve?
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. It can also cause vehicle emissions to increase.
What could cause a P0404 code?
Code P0404 is triggered when the EGR position is not as the ECM expected and the most common cause is the EGR valve partly stuck open from carbon buildup on the valve pintle.
What is an EGR valve do?
Within modern internal combustion engines, Exhaust Gas Recirculation (EGR) is a method to control Nitrogen Oxides (NOx) emissions, produced as a by-product during the combustion process. The function of the EGR valve is to control the flow of exhaust gas being recirculated depending on the engine load.
Where is the EGR valve located on a 2008 Dodge Grand Caravan?
On the 2008 and up 3.3 & 3.8 engines the EGR valve is located on the right side of the engine just behind the coil pack.
When would the EGR valve release exhaust back into the system?
When the engine is idling, the EGR valve is closed and there is no EGR flow into the manifold. The EGR valve remains closed until the engine is warm and is operating under load. As the load increases and combustion temperatures start to rise, the EGR valve opens and starts to leak exhaust back into the intake manifold.
What does diagnostic code P0404 mean?
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.
What to look for in a p0404 Dodge?
Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P0404 DODGE code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type.
Can a p0404 engine have too much EGR?
(Too much EGR and the engine won’t idle). If you have a P0404, then the EGR valve is likely an electrically controlled EGR valve instead of a vacuum controlled EGR valve.
Is the p0404 valve on my Malibu gone?
I have a 2002 Chevy Malibu LS with the 3.1L V6 engine. I had a p0404 code and when I did my tune-up recently, I went ahead and replaced the EGR valve. However, after two days of normal driving (approx. 70mi each day), the code has not gone away.
What causes the EGR valve on a Dodge Caravan to go bad?
While there are several issues that can throw the P0404 code in the Caravan, the most common issue is either going to be carbon buildup on the EGR valve, the EGR valve itself (going bad), or wiring issues. Most of the time, the only symptom of P0404 is going to be the service engine soon light itself.
