The Dealership told me the 1996 models have an extended warranty up to 150,000 miles. It covers this problem.

Did you replace the EGR valve, or the volume control solenoid valve?

Egr insufficient flow


NO YEAR, STATED.
NO ENGINE STATED.
now that makes this hard, no? my only clue is the body shell.

why not post the DTC error , not your interpretations?
on newer cars there are up to 5 or more EGR DTCs.
the exact dtc or the lack of some , tell the FULL STORY.
for example on newer cars there is EGR feedback readings.

btw: i own a 04GV and have 100%+ documentation on it and can fix any EGR fail on any car made, sure can. GEN1 , to GEN now.
but need more INFO.

pull you egr valve off and get some brake parts cleaner or carb or throttle body cleaner and clean your valvue also start the car with the valvue off and give it a little gas so you can blow all the stuff out of it then put it back on and erase the codes then drive and see if the check engine light comes back on

Engine light comes on so they scan it and they told me egr valvue


The problem is that your EGR valve needs replaced. What these do is they allow a precise quantity of exhaust back into the intake manifold; Provides a great help for an efficient combustion process and improved engine performance, when thes go bad your perfomance drops off and it does not run as clean.
The EGR valve, or Exhaust Gas Recirculation valve, is a vacuum-controlled valve which allows exhaust back into the intake manifold in controlled amounts. The EGR valve can clog and get contaminated over time by carbon buildup, at which point it will require replacement. A malfunctioning valve can cause the engine exhaust pressure to drop and send engine warnings to the computer. It can also cause engine back pressure to drop, reducing gas mileage and engine
This is for a dodge ram, as I have no idea what car you have but this is a general tip.
  • Locate the EGR valve in the engine bay. The year and make of the Dodge vehicle determine where the valve is located. This is on the front of the engine block, next to the timing belt in model-year 2005 and newer trucks. In older vehicles you will typically find the valve behind the engine, near the firewall.

  • Unclip the exhaust tube from the side of the valve. You can do this by hand. Shift the tube from side to side until it slides off.Use a flat-head screwdriver to remove the EGR valve from the exhaust tube. There is a screw on each side of the tube.

    Disconnect the harness from the EGR valve. Use your hand to pull up on the tab and slide the harness from the valve.

    Use a flat-head screwdriver to remove the two screws that secure the EGR valve to the cylinder head. Remove the EGR valve and clean the surface of the cylinder.

    Attach the new EGR valve to the cylinder head and tighten it down with the same screws that were previously installed.

    Reattach the harness and reattach the exhaust tube to the valve. Tighten the two flat-head screws that hold the tube to the valve.

    Reattach the hose to the valve and use your hand to attach the clip to the hose.

    P0406 - Exhaust Gas Recirculation Sensor A Circuit High

    Early Models : The EGR valve control the amount of exhaust gas routed to the intake manifold. Vacuum is applied to the EGR valve in response to the throttle opening. The vacuum control the movement of the taper valve connected to the vacuum diaphragm in the EGR valve.

    zjlimited_230.gif

    Late Models : The EGR volume control valve uses a step motor to control the flow rate of EGR from exhaust manifold. This motor has four winding phases. It operates according to the output pulse signal of the ECM. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes, changing the flow rate. When no change in the flow rate is needed, the ECM does not issue the pulse signal. A certain voltage signal is issued so that the valve remains at that particular opening.

    Symptoms
    - Engine Light ON (or Service Engine Soon Warning Light)
    - Engine hesitation

    Possible causes
    - Harness or connectors (EGR volume control valve circuit is open or shorted.)
    - EGR volume control solenoid valve
    - EGR temperature sensor and circuit

    Possible solution
    - Repair EGR harness or connector
    - Replaced EGR volume control solenoid valve
    - Replaced EGR volume control valve
    When is the code detected?
    - An improper voltage signal is sent to ECM through the valve


    Hope helps.
