'09 Dodge Ram 1500 EGR Valve
My check engine light turned on the other day. The code is P1404 which I understand could mean it's a bad EGR Valve. I downloaded the service manual and found where it is and I don't see how I'm supposed to get back in there to take it out let alone put a new one in...
I'm not an expert at this stuff but I don't mind trying to do it myself. However, I could use some tips on how to get back there and take it out and put in the new one. Please post if you have experience with this and can give me some helpful info on how to do it.
I did a quick search and found the below. I would recommend checking all your connectors before replacing the EGR. After doing this, you want to try this:
1. Disconnect the wire harness from the EGR valve.
2. Turn key ON and erase the trouble code(s) from the car's computer AND TURN KEY OFF IMMEDIATELY WHEN THE SCANNER SAYS CODES HAVE BEEN ERASED. DO NOT TURN KEY ON BEFORE YOU RE-CONNECT EGR WIRE HARNESS.
3. Re-connect EGR wire harness and your problem should be fixed.
I learned this fix from OBDII.COM where carfixer and kozloski discussed it and I think kozloski was the one who provided the solution, so thanks to them.
There was also other people stating that this fix really works. Now I have joined this group of people as I got mine fixed using this trick also.
I believe erasing codes with wire harness disconnected and turning the key OFF right after P1404 code has been erased re-sets the 'Valve Close Position' reading in the computer and triggers computer to re-learn position next time the key is turned ON.
Good luck and let us know if this works.
I suppose that might be a viable solution assuming there is no carbon holding the pintle off the seat that set the code to begin with.
