good luck getting to it!

pre-soak those bolts with some rust penetrating oil HOURS before you even tackle this job

i took my car to NA Auto Repair they did a great job at very resonable rates

I am so sorry to say there ware likely about 50 or more reasons that light is coming on.
An expert will need to find out which one, or several, of these parts is bad.
Know that the modern technology has almost gone beyond understanding of mechanics, so it can could you many dollars and trips for repair to fix this.
I maintain several cars, and am constantly fighting these problems.
Sorry to be un-helpful.

• EGR valve for a 1996 Chrysler LHS

  Passenger side near the firewall. Look for a piece of plastic clipped to a metal bracket and the plastic will have EGR on it. This is a two piece system, follow the hoses for the other part. hope this helps .
  

i would remove the egr and just the passage to make sure it is not filled with carbon. common problem. here is some info for you as well.

Circuit Description


The linear EGR system consists of a linear EGR valve, the PCM, and its associated wiring. The EGR valve solenoid is controlled directly by the PCM when certain conditions have been met. The PCM contains a diode feedback circuit which dissipates energy when the valve is cycled OFF. When the PCM commands the EGR valve closed, a closed valve position value is learned. If the PCM commands the valve closed and the actual feedback value does not match the learned values, DTC P1404 will set.
Conditions for Setting the DTCImportant: When the PCM recognizes that the parameters for setting DTC P1404 have been set, the diagnostic software waits until the EGR cycles open 50 percent or greater 4 times and then resets. If after the 3 cycles the actual vs learned is not within the parameters, the DTC will be stored and the MIL, service engine soon, will be commanded ON.
Important: When this DTC sets, functions will be disabled. When repairs are complete, codes must be cleared and the ignition keyed OFF for at least 10 seconds to allow proper operation.
DTC P1404 will set when the actual closed value does not match the learned closed value within 20 seconds if:
• RPM is below 5,000 and the actual vs learned is greater than 0.2 volts. OR • RPM is above 5,000 and the actual vs learned is greater than 0.4 volts. Diagnostic Aids • Check for backed out or damaged terminals. • Check for a stuck open EGR pintle. Inspect the EGR pintle valve bore for carbon or debris and remove. Verify that the pintle moves freely and the return spring forces the pintle closed. • An open in circuit 452 will result in DTC P1404. • A short to ground is circuit 697 will result in a severe rough idle and driveability complaint and set a DTC P1404. • Compare the learned closed pintle position to the actual closed pintle position with the key ON and the engine OFF. If voltage differs more than 0.15 volts, check for backed out, damaged, poor terminal tightness, or an intermittent open in circuits 416 or 1456.

It's on the drivers side of the engine, on top, right behind the throttle body. Its bolted to the upper plenum, has a four wire connector (I believe), and is round in shape.

In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.

• Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticeable difference in RPM's with the EGR open

• Clean out the EGR valve and/or tubing to remove deposits
• Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
• Replace the DPFE sensor (with a good quality / OEM one)

The problem with the Warning system for the EGR is it usually blames insufficient flow to the sensors that measure the flow.

What is really happening is the intake manifold is clogging under the airhorn mount. The airhorn has a butterfly flap on it and mounts where the carburetors use to be. The EGR gets its flow from passages beneath the airhorn. You need to clean the passages to the EGR. Then remove the battery cable for 10 minutes to clear the old codes. The check engine code should go away when the manifold is clean.

The EGR Valve Location is typically housed on the intake manifold this schematic may help you
