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

Got a 1404 code manufacturer controlled auxiliary emission controls


This code shows up if you have a bad or clogged EGR valve, find your EGR valve if you can, clean it, this should clear the code.
If, after cleaning, code returns then you need to replace it.

Service engine light comes on with obd code of p1404, p0405. What do i check ?


Code 1404 for Saturn cars means the computer thinks the EGR is not closing. But it can also mean the computer needs to be re-programmed. There are service bulletins for some models.
Code 405 is a problem with the EGR sensor which can be causing the other code.
Generally the sensor is telling the computer the valve is not closed when the computer commands it to be closed.
It may be tough to fix if the problem is not constant.

I have a 1998 gmc 4x4 that code 1404 has poped up and i would like to know what it means and what to do to fix it


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

2006 dodge ram hemi 5.7 liter trouble codes 1404 and 405 and check engine light on


The check engine light is on to tell you that the ECU has detected a fault. The faults are stored as codes. The codes both have to do with a deficiency of exhaust gas going through the EGR valve. You will need to find out if the problem has to do with the valve, a leak, or the circuit.

2001 grad prix code 1404 egr valve is good but still throws 1404 code any help would be greatful


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 Valve replacement and Check engine light


Error code will have to be cleared. The way that cars know when to turn on the check engine light is that there is a recurring error for "x" miles or time, as long as that error exists in it's memory most cars will continue displaying the check engine light.

DTC Code of a 1404 , and also a IAT High input malfunction


sounds like the IAT is disconnected, it is either in the flex hose from the air cleaner to the engine or in the air filter housing, on my GM product car it is in the air intake hose, it is small and has a 2 wire connector to it, just pushes and pulls in and out of the flexible air intake hose.
