P1404 is the EGR Pintle Position (system) and the fault
description is "Circuit Fault".
in reality, the best thing is to take the whole intake off and do a good house cleaning,since all the passage ways(i.e. vacuum routes, etc.)gets plugged.
the pintle gets stuck by all the **** inside the manifold, usually having the engine running too rich.
the original culprit is(most of the time) the faulty engine coolant temp sensor.
with that going bad, is usually downhill for performance and everything wise ...lol
now.i think I've exhausted the subject for all the peps...

What is the fix for (egr flow sensor a) on 2007 dodge hemi? This code came up when light came on.


It is probably the EGR valve itself. I would remove the valve and check the lines coming off of it to make sure it is not clogged. If that checks out ok then I would replace the EGR Valve and then clear the code with a scan tool.

I am getting a light with code P1404 EGR on Ram


I would clean out the EGR valve and reset the fault code, if the valve is coked up it can stick and cause your problem

I am getting a light with code P1404 EGR on Ram


If you have an exhaust leak this can cause false emission readings. On a vehicle as old as your's I would bet on changing the EGR valve if you don't have an exhaust leak.
As to having your computer re-flashed, I far as I know that's for if your not properly registering a new EGR valve.

Diagnostic code 1404


Trouble code P1404 means: EGR Close Position Performance
basically pull off the EGR and try to clean it up, if that doesn't work it will need to be replaced.
Hope that helps!

Whats the code p1404 mean in my 2006 dodge ram


Hi,this is an errror code that indicates Exhaust gas recirculation ( EGR) valve---- closed position performance.
In other words, the pintle or valve inside is stuck in the closed position and not recirculating the exhaust gases.
You can either take it off and try to free up the valve, or replace it with a new one. Have it checked first, it could also be the EGR valve solenoid causing it not to open,

take care

What is this code P1404 on the dodge ram 1500 mean


That code is the EGR. I'd start by checking for a bad connection on the EGR plug-in. Pull the connector off and inspect each individual terminal inside the plug and the connector pins inside the EGR valve.
I found this solution at another forum on this issue. It worked on my 2001 Grand Am:

"Many GM built cars have a tendency to have the 'Check Engine Soon' light come on as a result of DTC code P1404. P1404 is described as EGR valve pintle stuck open, which in most cases is a false alarm. I had this happen with my '01 Grand Am. A little bit surfing on internet reveals that GM has a solution for the problem, a re-flash for the car's computer.

A software re-flash as a fix kind of indicates that the vehicles with this problem were built with it but I don't think GM will be re-flashing cars outside warranty for free. They will want their $100 for it.

Some hands on people I found had purchased a new EGR valve and changed it but the problem remained.

Possible reason (very likely) for the false P1404 code is that the plastic piston of the EGR valve position instrument (LVDT?) wears over time and starts reading a different position at valve closed than what it was when the EGR valve was first installed.

When the car was built and the computer circuits energized for the first time the computer learned the EGR valve closed position signal from the valve position instrument that is built on top of the valve itself. Over time, when the instrument wears, a slightly different signal is sent to the computer and when it differs enough from the 'Valve Closed Signal', that the computer had learned, the trouble code P1404 is set and the 'Service Engine Soon' light comes on.

Replacing the EGR valve with a new one does not necessarily fix this problem because the 'Valve Closed Signal' between valves is slightly different and it is just pure luck if your new valve would give a 'Valve Closed Signal' close enough to your original valve's signal not to set the trouble code. This is why the new EGR valve 'Valve Closed Signal' must be re-learned by the computer.

So, what this all means is that if the P1404 is a false code meaning that the valve pintle is not stuck open, then new 'Valve Closed Signal' can be re-learned by the computer using the old valve.

For fixing this problem the tool you need to have is a simple OBD II code scanner that can be used to erase trouble codes. There are many scanners of different price range on the market. I purchased one from AutoZone for about $90.

A code scanner is a very handy tool to have and I recommend everybody who is just slightly hands on type of a person to get one. It will end up saving a lot of money over time.

The fix goes like 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.

If you don't have an OBD II scanner and don't want to buy one some car part stores may erase the code for free, but if you have it done there you must tell them about turning the key OFF at the right moment. Other wise the re-learn process does not take place.
