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

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.

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

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.

What are the probable causes of DTCs P0400, P0171, P0174 y P0302?


DTC code PO400 could be caused by a clogged EGR valve or EGR tube. try cleaning the EGR valve, tube
DTC code PO171 is fuel system too lean bank 1
DTC code PO174 is fuel system too lean Bank 2
Most likely suspects are O2 sensors, But can be caused by vacuum leaks and also can be Mass airflow sensor (MAF) try cleaning with electrical parts cleaner
DTC code PO 302 is a misfire at cylinder # 2
Check spark plugs and wires
Try cleaning the EGR Valve first along with changing the spark plug first, and see if any codes erase, in other words start with the cheaper fixes first, as some problems can be causing the other other codes

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!

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.

Egr valve cleaning


Usually the EGR valve problems show the fault code P0400 - Exhaust Gas Recirculation Flow Malfunction

What does that mean?
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
