Egr valve replaced and check engine light comes back on with p0405-check wiring at connector-if ok try performing at battery static discharge-disconnect both battery cable ends-and touch cables together-this discharges all ecu capacitors and resets adaptive memory

Its the solenoid controlling the EGR valve movement that is likely at fault. if theres a vacuum pipe running from the EGR valve it goes to a solenoid that opens and closes the valve. If it just has an electrical connector on top of the valve, the solenoid is built in. If its built in you probably have a wiring fault at the connector or in the harness to it.

I have a code PO 442, PO 455 in my 2003 dodge Grand Caravan, check engine is on. 2007 Town Country, i have codeP 1404, PO404


The p0442 is a moderate leak in the EVAP control system and p0455 is a large leak in the EVAP control system. First thing is to ensure that your filler cap is on tight and that the seal is effective. Next is to check the tubing of the EVAP system for any holes or disconnections. The P1404 is the valve in your EGR (exhaust gas recirculation) is staying closed. It could also be that the EGR piping is clogged up with soot (baked carbon deposits). Similarly the p0404 is an EGR related error code. Your vehicle is quite new and it would be unusual for the EGR to pack up or require cleaning out so early in its life. I would make sure that the connector pins in the connection socket to the EGR are clean and bright and that there no breaks in the wiring back to the power control module. If no joy then remove the EGR and examine the freedom of movement of the valve. If gummed up spray liberally with carburettor cleaner spray and leave to stand for at least ten minutes before wiping away the crud. Repeat until the valve looks like new and reinstall. After four or five restarts without fault the error code should clear.

What will be wrong if I got code p0406 and p 404


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
clear codes
test drive

Have a 2005 dodge ram with 5.7 hemi has an eng


Dodge/Chrysler EGR valves are known to be unreliable. The one on my wife's 05 Grand Caravan died in the 40k miles range.

They are not really serviceable. The usual fix is replacement. Part will be between $50 and $150 depending on where you get it. Installation most of the time is 2-4 bolts and the harness.
