EGR Valve ODB2 Code 1404

Check the wiring for power and ground. Then check the wiring for resistance from the EGR to the ECM. You will need wiring schematics. If this checks out, then there is a computer reprogram that can be done. Dealer.

The Powertrain Control Module (PCM) monitors the Exhaust Gas Recirculation (EGR) valve pintle position input to ensure that the valve responds properly to commands from the PCM. When the ignition switch is turned ON, the PCM learns the EGR learned minimum position. The PCM compares the EGR learned minimum position to the EGR position sensor when the EGR valve is commanded closed. If the EGR position sensor indicates that the EGR valve is still open when the PCM is commanding the EGR valve closed, this DTC will set.

A scan tool that is capable of commanding the EGR circuits on and off is required to verify EGR performance and sensor feedback voltages at the PCM. However, this code is USUALLY caused by carbon getting stuck in the EGR pintle and holding it open. A good cleaning is usually all that is required to fix this.

You will need an EGR gasket. Remove the EGR valve and inspect the ports for heavy carbon deposits. These deposits can usually be cleaned out using screwdrivers and a piece of mechanics wire to break the carbon loose and some carb and choke cleaner to finish the clean-up. A wire brush and some carb cleaner usually works for the EGR valve itself. Once the ports and the valve are clean, re-install the valve using the new gasket. Clear the codes and drive the vehicle to see if the problem is fixed. Please note that the EGR monitor runs at speeds over 50 Mph. during deceleration, so you need to get the vehicle on the highway for a valid test of the EGR system.

If the Check Engine light does not come on during the road test, Connect a code reader and check the OBD readiness monitors. If the EGR monitor says "complete" and there are no codes in the computer, then you have done a successful repair.

Yuo don't say what year or model but im almost certin that this is the EGR valve pentile valve is eighter stuck open or is not sealing correctly. Witch baiscly means you need to replace the EGR valve and clean where the pentile seals to the intake manifold under were the EGR valve it mounted on the manifold

if its the 3.3 then the code would be--0406 egr sensor A curcuit high--- the common fix is to change the egr valve assembly which includes the egr transducer. This egr valve has also a high failure rate and you can check this out by calling the Dodge parts dealer. good-luck !! once egr valve is replaced. have light turned off with scanner. because if it stays on, pcm thinks it still has the problem. it will not send right info to pcm.

EGR Valve Closed pintle Position This valve is located on the intake manifold near the carb (behind I think) It looks like a flying saucer on its side with a six sided raised portion and a vacuum line going into it. If you push on the valve diaphragm (side opposite the raised portion I mentioned earlier) it should move in and out without too much effort. Be sure the engine is cold to prevent burns. If the valve is stuck - replace it. There also may be a filter in on a bracket near the valve if your vehicle is equiped with an electronic VRV (Vaccum Regulator Valve) Hope this helps. Let me know. Thanks

Ensure the connector wiring pins fit snug at the valve.
A loose pin fit could cause this fault. These EGR's due fail quite often however. I know you say it is good however a solenoid may be failing when hot.

EGR flow is monitored by the PCM by it looking for a reaction in the FRONT O2 sensor in responce to the command given to the EGR valve. The linear electronic EGR valve sends a return signal to the PCM indicating the relative position of the step motor and hence how far open (or closed) the EGR valve is in responce to the PCM command. The PCM expects to see (within a set of given parameters) a change in the O2 sensor reading (change in exhaust gas make up) after the EGR valve is commanded open or closed. If it doesn't, or that change is not within the expected parameters, a code will be set based on the skewed data. Generally a "insufficient flow" code will be set by:

1.Faulty EGR valve (sticking, or "lying" to the PCM about the actual valve position)
2.Faulty electrical connection at the EGR valve (causing false data)
3.Clogged EGR passages
4. Bad read from the MAP, or TPS, causing the PCM to misinterpret the EGR data based on faulty operational data from the other sensors
5. (Very rarely) A marginally "slow" O2 sensor. (PCM does not "see" the change in exhaust make up quick enough and interprets that as poor EGR flow.) I have found that normally this code means that the EGR is not opening the amount that it has been commaneded to by the PCM. Normal cure for me lately has beed to repalce the EGR valve and to clean out the passages while the valve is off. The Tech 2 is able to command the EGR open and show the commanded opening and the actual opening. When this code is present the actual and commanded do not match closely at all.

unhook the battery for ten minutes and hook it back up... that will clear the code... if your stereo requires a code make sure you know it first.

Please take a moment to rate this solution thanks

Hi...
The code P1404. The especification is:
EGR ( exhaust gas recilculation) Closed Valve Pintle error.
Check the condition of the EGR valve.
Check the connector for damaged pins. corroded or broken.
Remove the EGR Valve and see the PIntle, some times is there a piece of carbon making obstruction on the hole of the EGR.
Clean and install, Clear the code and Drive to see if the code return,
If the code return Replace the EGR valve,
If not, You done...

I hope this help on your question....
Thank you for use fixya....

Good Day,

Your best option is to replace the EGR(exhaust gas recurcilation) valve with a new one. For pics and detailed instructions on the process see this link:

Once replaced you will have to clear the trouble code by disconnecting the negative battery terminal, re-connect after a few moments.

Hope this helps
