Check the vacuum line going to the valve and the transducer, this is the black plastic rounnd thing between the egr valve and the intake, chances are the transducer is bad and can only be purchased along with the valve. if you have access to a vaccum gauge you can connect it to the line at the egr valve and raise the rpm to 2000rpm and see if it pulls vacuum, but you can probably count on buying a new valve assembly.
it will come with the tranducer which is probably allyou need. hope this helps.

There is an egr control solenoid on these that always fails. I believe the only way you can buy them from the dealer is with the egr valve also. If so, you really just need to install the solenoid which is pretty easy.

    The solenoid and transducer are the same piece.

2007 Dodge Grand Caravan Engine Light Code P 0405 ?


P0405 is an Exhaust Gas Recirculation fault. This could be a faulty valve. You could try cleaning the valve first, chances are it will need to be replaced in the long run. Hope this helps...

both codes po406 and po404 refer to a fault in the EGR system
Po404 > Exhaust Gas Recirculation Circuit Range/Performance not within proper range.
Po406> Exhaust Gas Recirculation Sensor A Circuit High (meaning the circuit is open or disconnected)
Without actualy checking the voltages (wiring)
Replace the EGR valve

The car dies sometimes when idle and sometimes when traviling at


he EGR valve, or Exhaust Gas Recirculation valve, is a vacuum controlled valve which allows a specific amount of your exhaust back into the intake manifold. This exhaust mixes with the intake air and actually cools the combustion process. Cooler is always better inside your engine. The exhaust your EGR valve recirculates also prevents the formation of Nitrogen related gases. These are referred to as NOX emissions, and are a common cause for failing emissions testing. Unfortunately, your EGR valve can get stuck, causing NOX gases to build up. You'll know if your EGR valve is stuck or malfunctioning because your car will experience symptoms like rough idle and bucking on accelertaion.
