Did you reset the system and the light still comes on? If so you have a possible wiring problem or a plugged EGR passage maybe. You need a scanner to check these things so if you don't have that you are stuck here and need the dealer or a good shop with correct kit to look into this.

SOURCE: EGR Valve - Engine Option Code

Hi, this is my first post. I had the same problem with my 2005 Grand Caravan. Great van, but all of the sudden, the check engine light came on, and then it started driving "jerky." I found this post, along with others on the web, and diagnosed it myself. Let me outline how I did that, since this will accumulate info from several different sites:

1. I turned the ignition key from the "on" to the "run" position about 5 times, and a code showed up in the mileage slot. My code was P 0404, which read more like "tripP 0404".
2. I looked up that code on google, and also asked the guy at Autozone. Both said it was a bad EGR valve.

**Side note: there is a little thing here in the 2005 Grand Caravan called a "XZZ Option Code" in relation to the EGR valve. As in, when you go to get a new EGR valve, they are going to ask you if you need the "XZZ Option" or the "XZZ Exception." When you ask the guy at Autozone what the difference is, he doesn't know. So, after a little research, the difference is this: if your VIN has the letters "XZZ" in it, then you need the "XZZ Option." If your VIN doesn't have "XZZ" then you don't need that option. (Thanks a lot, Dodge, for that bit of stupidity.)***

3. Autozone didn't have the EGR in stock, but Federated Auto Parts (aka KOI, in our area--Cincinnati) had five in stock, so I got one--it cost me about $85.00
4. After getting home, I changed it out, in the following steps.
a. I disconnected the battery.
b. I disconnected the electrical line coming to the EGR (by the way, the EGR sits just above the alternator...and if you don't know what the alternator is, take the parts to your local mechanic and ask him to change it out for you...)
c. I disconnected the vacuum line that comes into the top of the EGR, as well as disconnecting the other end of that line, just to get it out of the way. That took 4 bolts, and they were 8 mm.
d. I removed the two bolts (10mm) holding the EGR in place, and they were a bit tight to get to. I would suggest a 1/4" drive U-joint to get to the bottom one, but a two inch extension held just right will get the job done--I didn't have the u-joint for my socket so it can be done without it...not much fun though.)
e. I replaced the metal gasket (it came in the box with the new EGR), and reversed the steps to put everything back together.

After restarting and test driving the minivan, I have no check engine light, and the "shuttering" is gone. I'm about to drive to Texas next week...we'll see if it solved the problem. More news later.

I love the internet. Ride free, citizen!

SOURCE: getting the error code P0442 with a ODB2 on 2004 Caravan

Code 442 indicates a vapor leak in the EVAP control system. Fuel vapors are routed through hoses to the EVAP charcoal canister, then via purge control valve, are rerouted through intake when engine running. Bad gas cap seal is the usual culprit, which you can try cleaning the seal & filler neck where it screws in, then erase codes & try again & see if it comes back, or may require new gas cap. Other areas to look is at hoses running to & from canister & purge valve for any crack that may be a source of leak.

SOURCE: code p0406 dodge grand caravan 3.8 engine. Is it

P406 is a EGR code, EGR will also cause a knocking/ pinging sound when there bad. Very common problem. The position sensor inside the valve goes bad. Your going to have to replace the whole EGR valve and it can put out variety of codes from P0401 to P0406. The new valve will solve the problem and easy to replace, you can pick one up at Auto Zone and they can give you the step by step instructions to replacing the EGR with common tools. Good luck and hope this helps.

How to clean a egr valve from a 2000 mitsubishi montero. I replace the egr valve, but still engine ligth code 403 still on.


Your new EGR valve (assuming it wasn't defective out of the box), is fine, but the car's computer just needs to have its code 403 cleared. Even though you've corrected the problem, the computer will still light the "Check Engine" light, and store code 403 until the code is cleared using an OBD-II (On-Board Diagnostics 2) code scanner.
Note that the car will function perfectly with its new EGR valve, a lit "Check Engine" light and a code 403 stored. Its just a good idea to clear the code, so that then only NEW problems will become the reason that the "Check Engine" light gets lit.

I have a 1998 dodge stratus and the code 403 egr flow cicuit malfunction comes up how can i fix this problem so i can pass inspection


Check all vacuum lines to the EGR valve, the EGR valve is between the intake and the exhaust, EGR stands for Exhaust Gas Recirulator valve. It must be able to flow properly in order to pass emissions anyway if they do a smog test.

Engine check light, code 401 low egr vacum egr


The EGR and the lift sensor may look perfect from the outside but the under side of the EGR valve and the EGR passage (small tube) are the REAL WORKING parts.

The carbon inside the EGR passage tube and the underside of the EGR valve must to clean out.

Make sure you has a NEW EGR gasket before you start the job.

It's a 2-3 hours job.

If you do not clean the EGR passage tube the Nox emission will get higher (check you past emission reports).
