2005 Grand Caravan bad EGR

The second Code 404 is for a problem in the same area. It is about the performance of the EGR valve circuit.

Cleaning the ports is a good start. Also checking for a clogged EGR passage beneath any mounting gasket would be a prime place to look.

I deal mostly wth Ford products and this is similar to their problems. Apparently the sensors on both brands are installed downflow of the EGR and triggering sensor. On the Ford products, when airflow through the EGR is measured and found to be weak or non-existent; it blames the EGR and sensor for not opening to provide flow. The actual problem is there is a clogged flow passage. The parts are often fine. You can not have flow at the ending, when you do not have flow to begin with.

So many parts are replaced needlessly because of this misengineered system. Now it is debateable that a sticking EGR could cause the passages to be blocked. It becomes an argument of which causes which in the first place, so you did not hurt anything by replacing the parts. You are just not finished with prepping the area for the repair.

I hope my explanation is helpful.

I have a 96 dodge neon. when it gets to 1000 rpm's or lower it stalls out. i got a new fuel filter. there are no leaks in the hoses. what could be the problem?

your problem may be a bad iac ( idle air control ) valve. also check or clean egr valve passage way to engine. or the egr itself is stuck open. ( exhaust gas recirculation ) valve.

1990 Dodge Dakota Smog Issue


PPM of Nox or Co or HC?????

The base of the EGR and the EGR air passage tube will collect carbon over the years.

Most car over 65,000 will fail Nox and has high CO because of the partly block passage.

The only way to clean to the air passage tube is with a lot of WD-40 or similar cleaner.

The EGR valve can be clean or replace under $68 ////gasket for around $3.

Make sure there is NO LEAK when you put the EGR valve back in place.

Please post what PPM is failing on reply.

EGR code 1999 Dodge Neon

Hello, you could try pulling it and the pipe off and cleaning it before replacing it. An egr is pretty expensive. When you go to clean it use Carb cleaner.

I am having trouble with my speedometer not working occasionally and now my seat belt light is coming on sometimes too. Is this the instrument panel cluster? Or something else? 1998 Dodge Neon. Backstory is as follows: -We take very good care of it and have one dedicated mechanic. -It has only had two owners; my parents and I. -We replaced the battery 2 months ago. -Mechanic checked to make sure the speedometer sensor was working. -We have had issues with the radio for years where it will randomly turn on and off, typically brought on by a stuffed trunk OR wet weather. -The speedometer works until we hit a bump and then the needle flies up and down or sometimes just stops working all together. -Mechanic has made mention of there being some Chrysler specific battery cable that is a smaller side cable and it is not in good condition. -Currently, my problem is that I can't find an old 1998 Dodge Neon in the salvage yard because yards are doing a lot of 2002 and newer vehicles and automatically crushing the others. The meat and potatoes of my question is what direction do I go in? And what of these symptoms ties to each other? And will adding new solder to the points on the panel fix it or is it something else? I'm trying to find least expensive to most expensive options and I'm rather handy but can't drop an engine or transmission or anything so keep this in mind. My handiness ends at resoldering the pins BUT I do have a mechanic I trust, but I fear that maybe I'm not combining symptoms properly. I have the money to repair an item I KNOW is wrong but not to chicken hunt around for problems.
