Where is the EGR valve in a 2004 Dodge Intrepid?

I'm trying to track down the source of a P0400 engine code problem which points anywhere from the valve EGR valve itself to the solenoid, need to know where it is in this car

SOURCE: no vacuum to egr valve

there is an EGR vacuum solenoid somwhere that controls on/off vacuum to actuate the valve. i am not to sure of the location, but follow the vacuum line back from the egr until you find a device that looks like an electrical check valve for vacuum. that is a possibilty. but then again i am a ford,chrysler guy and am just giving you an answer based on my understanding of the functuality of a vacuum egr system

SOURCE: how to replace EGR valve on 99 Chevy Tracker

Take off your EGR valve and clean it out with carb cleaner also
grease tyhe little screw thing in it,,, u will c what i mean if u take it apart. carbon builds up in the chamber. it is located at the back left side of your engine and is a bit of a pain to take off. this should save u the cost except for the cleaner and labor. i had the same problem cheapest i found was 90$ on ebay.

SOURCE: Replacing the EGR valve on a 2004 Dodge Caravan 3.3L engine

I repair mine last summer,
It is on the exast port, left.
You have a tube attach to it, going in the Head Cover.
Easy to change. it cost me $105.00CND at the dealer

Good Luck

SOURCE: code p0400 keeps coming up after changing the egr valve and sol.

It may be that the passage to the exhaust is blocked also.

Check the EGR air passage tube again.

You may miss some on the first pass.

====


Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

99 maxima ran till it was parked now it turns over will not start gave code p0400 any ideas


The fault is somewhere around the EGR valve - probably the EGR valve or the throttle position sensor.

Before replacing any sensors try removing and cleaning the EGR.

Here's a Youtube link that may be of help to you:

My 2004 Sebring 2.4L does not have an egr valve. The engine light is on light is on with and error of p0400 . So what now?


Hi Gerard, I'm glad to help. Gerald, I work on these everyday almost. The EGR Valve is located at the rear of the engine which would be near the brake fluid reservoir. It's way down low to the right under the exhause pipes very hard to see very hard to get to. When you replace it, get from the dealer and it will come with a new vacuum valve or at least it used to. You'll also need to clean the tube out because it will be full of carbon build-up and also make sure the hole in the cylinder head where it mounts is not blocked. Hope this helps and have an awesome day Gerald!

My 2004 Sebring 2.4L does not have an egr valve. The engine light is on light is on with and error of p0400 . So what now?


With the code coming up for an EGR valve I would consider it unlikely that it left the factory without one as it would have had the code from day one and it would have been fixed at a service under warranty.. If you got the car second hand then it is possible that the EGR valve failed and the previous owner found it easier to blank it off to sell it . I would consider fitting a new valve and getting it working properly as it is critical to passing the road worthy certificate., performance and economy.

P400 code on a 2000 mitsubishi diamante


P0400 - Exhaust Gas Recirculation Flow Malfunction
The exhaust gas recirculation (EGR) valve is vacuum controlled valve that regulates the amount of exhaust gases that re-enter the cylinders. The powertrain control module (PCM) determines how much based on engine load, temp, and other conditions. If the PCM detects that the amount of exhaust gases entering the cylinder were insufficient or non-existent, this code is set.

Symptoms: No symptoms will likely be noticed by the driver other than the MIL (malfunction indicator lamp). However, non visible symptoms will be increased combustion temperature and increased Nox emissions.

Causes: A code P0400 may mean that one or more of the following has happened:
Plugged EGR passage which restricts the flow of exhaust gasses
Faulty EGR solenoid
Faulty EGR solenoid wiring/harness
Vacuum lines damaged/disconnected to the EGR valve solenoid or to the EGR valve
Faulty EGR valve

Possible Solutions: Since EGR valve designs are different, no one test will suffice:
Using a scan tool, operate the EGR valve with the engine running. If the engine stumbles, the problem was likely intermittent wiring problem or intermittent blockage problem
If engine doesn't stumble, operate the EGR valve manually, if possible. If engine doesn't stumble and die, the ports are likely plugged. Removal of valve and cleaning of all ports will be required
Checking of solenoid can only usually be done with a scan tool, because most solenoids operate with a duty cycle of voltage, rather than constant voltage
Check all vacuum lines, hoses, etc for any damage
Visually inspect the solenoid harness and the solenoid for damage
Replace EGR valve

Hope this helps.

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.

2005 grand caravan error code P0400 egr valve chk/ performance


I have the 2005 Town & Country TOURING . If my memeory serves me correct, I believe this was the same code that I got on time. The van didn't seem to drive any different but this is what I did and I haven't seen the light come on since.
first I went to the dealer ( you can get these parts from a auto parts house also) and bought the 3 gaskets total.for the the EGR solenoid vavle assembly where it bolts on to the engine ( that gasket was made from metal), NOTICE AN INDENTATION IN THE METAL GASKET WHEN YOU TAKE IT OFF,YOU WILL WANT TO PLACE THE NEW GASKET IN THE SAME DIRECTION. one gasket that goes between the EGR valve solenoid and the small stand pipe. and another gasket that goes between the stand pipe and where it connects to the plastic valve intake area cover on top of the engine.
I took the EGR solenoid off from the engine and took it apart (reall carefully) and cleaned it thouroughly with a spray carbuerator cleaner. I took mine "completely apart" after I did this I dont recommend to do this again, you can damage the coil inside if you're not cafefully. I suggest just cleaning the valve and plunger ports, etc....
When it was completely dry I reinstalled the EGR solenoid on the van making sure I used ALL NEW GASKETS. The van hasn't produced the engine light since. I hope this helps.
