Easy to find it. Trace the vacuum line from your egr valve along its path visually. At the end of the hose, should be the switch your trying to find.

cleanout egr valve and troutle body . Or replace egr with new one, clean, check vacumm lines , check for clogged check , depending on modle of car you can pippoint problem as some have a common part problem depeding with make of car. But all have to do with exaust system. Insufficient flow exaust flow. Im not an expert, all I know it is related to this, I have it myself so im googling it.

Ford EGR valve

The OBDII fault code P0401 means that the engine computer has detected that the Exhaust Gas Recirculation (EGR) system flow is insufficient. Read more how the EGR system works below. What could cause the code P0401 - clogged or restricted EGR passages
- faulty EGR valve
- EGR valve stuck closed
- problems with the DPFE sensor (Ford)
- problems with hoses to the DPFE sensor (Ford)
- problem with the EGR vacuum switching valve (Toyota)
- clogged catalytic converter
- carboned up EGR temperature sensor
- vacuum supply issues at the vacuum-operated EGR valve
- electrical problems with the EGR valve control circuit
- engine computer problems

If it's stuck closed, you will feel no ill effects. If it's stuck open, the car will not idle right and be hard to start. If you're getting an egr trouble code from your accord, test the egr valve to make sure it's working; use your finger to push up on the egr valve diaphragm, while the car is idling....car should shake and shut off if the egr valve is good. The one vacuum solenoid that feeds the egr valve, on that generation accord, is known to go bad and cause the egr trouble code. Check that solenoid if the egr valve tests ok.

P0401 - Exhaust Gas Recirculation Flow Insufficient Detected

Possible Causes:
- Harness or connectors (EGR volume control valve circuit is open or shorted.)
- EGR volume control valve stuck closed
- EGR volume control solenoid valve
- Dead (Weak) battery
- EGR passage clogged
- Exhaust gas leaks
- Faulty EGR valve

Possible Solutions:
- Clean EGR Valve
- Replace EGR Valve
- Repair EGR harness or connector
- Replace EGR volume control solenoid valve
- Replace EGR volume control valve

The EGR valve is mounted on the intake manifold and has an opening into the exhaust manifold.

The digital EGR valve, used on all 1990 and later EGR-equipped engines (Except the 2.5L and 1994-96 3.8L engine) is designed to control the flow of EGR independent of intake manifold vacuum. The valve controls EGR flow through 3 solenoid-opened orifices, which increase in size, to produce 7 possible combinations. When a solenoid is energized, the armature with attached shaft and swivel pintle, is lifted, opening the orifice.
The digital EGR valve is opened by the ECM, grounding each solenoid circuit individually. The flow of EGR is regulated by the ECM which uses information from the Coolant Temperature Sensor (CTS), Throttle Position Sensor (TPS) and Manifold Absolute Pressure (MAP) sensor to determine the appropriate rate of flow for a particular engine operating condition.

Digital EGR Valve Testing:

This system must be checked using a Tech 1®or equivalent scan tool. Steps 4, 5 and 6 must be done very quickly, as the ECM will adjust the idle air control valve to compensate for idle speed.

1. Using a Tech 1®or equivalent scan tool, check for any diagnostic trouble codes and solve those problems first. Refer to the Diagnostic Trouble Code (DTC) lists later in this section.
2. Select "EGR CONTROL'' on the scan tool.
3. Start and run the engine, until it reaches normal operating temperature, then allow the engine to idle for 2 minutes.
4. Energize EGR SOL #1; engine rpm should drop slightly.
5. Energize EGR SOL #2; the engine should have a rough idle.
6. Energize EGR SOL #3; the engine should idle rough or stall.
7. If all tests were as specified, the system is functioning properly.
8. If not, check the EGR valve, pipe, adaptor, gaskets, fittings, and all passages for damage, leakage or plugging. If all is OK, replace the EGR valve assembly.

THERE ARE TWO SOLENOIDS FOR THE VRIS SYSTEM.THEY ARE BOTH LOCATED ON THE INTAKE NEXT TO THE FIREWALL.THERE IS A THIRD SOLENOID ON THE SAME BRACKET HOLDING THE VRIS SOLENOIDS AND IT CONTROLS THE EGR VALVE.THE 2 VRIS SOLENOIDS ARE SIDE BY SIDE.
