SOURCE: 2005 Chrysler T&C EGR valve solenoid problem

YOU NEED TO DISCONNECT THE BATTERY FOR 5-10 MINUTES FOR FAULTS TO CLEAR COMPLETELY..HAVE SEEN THIS PROBLEM BEFORE AFTER REPLACING AN EGR VALVE..IT WAS A TECH TIP FROM CHRYSLER ENGINEERING..THE EGR VALVE WAS THE PROBLEM,BUT THE PCM WOULD NOT LET THE CODES GO EVEN AFTER CLEARING THEM WITH SCAN TOOL..ALSO CHECK CONNECTIONS AT EGR CONNECTOR FOR SPREAD PINS

SOURCE: The 2.7l engine stalls while driving my 2002

The stalling is all related to why your Check Engine Light is on. Go to your local AutoZone and they can read your code with a OBD II scanner for free and let you know how to repair it. The Airbag light problem can also be solved at the same time.

SOURCE: I'm receiving an Error code

Some dealer you got there

PO441-EVAP System --Incorrect Purge Flow

They may have found an EGR Valve issue,
but they certainly blew off the EVAP Code

I would guess you have a bad EVAP Canister
Purge Valve or some other purge control

SOURCE: I changed the EGR valve on my '02 PT Cruiser

Its either a faulty EGR valve or it has carbon build up inside.Take valve off and clean carbon out using a non-chrlonated brake cleaner and wire brush.

Check engine light code P0401 98 Ford expedition


OBD-II Trouble Code P0401 - Insufficient EGR Flow

EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR. You may notice drivability problems such as pinging (a.k.a. pre-ignition knock) when the engine is under load or the vehicle is at higher speeds. There may also be other symptoms.

A code P0401 most likely means one or more of the following has happened:
The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
There is a blockage in the EGR (tube), most likely carbon buildup
The EGR valve is faulty
The EGR valve may not be opening due to a lack of vaccuum

Check it and keep us updated. Hope this helps (remember to rating this free answer).

I have the engine check light on my 2001 Hyundai XG 300. The codes I brought up with the OBD2 reader were P0100 P0115 P0120 P1600 What would you suggest is the problem and fix on this I also...


Welcome to FIxYa.com
Description of codes are:
P01600 - Serial cable malfunction-- check connection,
Po115-Coolant sensor-indicates a open or short-circuit in the engine coolant temperature sensor circuit.

The P0401 code is Insufficient Flow Exhaust Gas Recirculation System.

The code is set when the engien computer detects less than the requested amount of EGR flow when the engine is hot and is under load.

What usually sets the code is an inoperative EGR valve, or a carbon clogged port under the EGR valve.

On your engine, the EGR valve is vacuum operated, and there is a little computer-controlled EGR solenodi valve in the vacuum hose that detemines how much vacuum the EGR valve gets. If this solenoid is bad, or there is a vacuum leak in one of the hoses, the EGR valve won't open when it should setting the code.

Since the dealer already cleaned the EGR valve tube, I would suspect your problem is likely due to a bad EGR solenoid valve or a leaky vacuum hose to the EGR valve.


Here is the EGR solenoid valve part number and list price:

P/N 3946038750 $40.59



I would clear the codes first and run engine for two min and re-check codes.



Write to me of the findings and we will go from there.

P0401 Exhaust Gas Recirculation Flow Insufficient Detected replaced the EGR valve but "check engine light" comes back on with same P0401 code


check the metal line that comes off the exhaust and make sure it isnt plugged with carbon. also remove the egr and check the port and see it's clogged as well

Engine lt on


There is a vsv (vacuum switching valve) located under the intake manifold that goes bad very often causing this code. Its hard to get to. Follow the hoses from the black plastic round valve(egr modulator) you see next to the EGR valve to find the vsv.

I just bought a 1997 Mercury Sable it was a private sale. Once I got it home the check engine light was on can't remember the code but it when I looked it up it was the canister purge valve. Spent $80. for...


P0401 insufficient EGR flow.

Possible causes:
  • Fault in vacuum supply to EGR vacuum regulator solenoid.
  • EGR valve stuck closed or iced.
  • EGR valve diaphragm leaks.
  • EGR valve or flow path restricted.
  • EGR vacuum hose off, plugged or leaks.
  • VPWR circuit open to EGR Vacuum Regulator solenoid.
  • EVR circuit to PCM open.
  • EVR circuit to PCM shorted to PWR.
  • Differential Pressure Feedback EGR (D.P.F. EGR) sensor pressure hoses both connected improperly.
  • D.P.F. EGR sensor pressure hoses reversed.
  • D.P.F. EGR sensor VREF circuit open.
  • Downstream pressure hose off.
  • Downstream pressure hose plugged.
  • Damaged orifice tube assembly.
  • Damaged EGR Vacuum Regulator solenoid.
  • Damaged D.P.F. EGR sensor.
  • Damaged PCM.



P0443 indicates an intermittent EVAP canister purge valve circuit failure.
Possible causes:
  • Intermittent EVAP canister purge valve or VPWR circuit open.
  • Damaged EVAP canister purge valve.

Engine light on in 2000 Dodge Grand Caravan - code P0401 What does that code mean?


it is your EGR Valve. EGR stands for Exhaust Gas Recirculation. It is part of the vehicle emmissions system, and is used to reduce combustion temperature and pressure to control Oxides of Nitrogen. There are generally three parts to the EGR system: the EGR valve
, an actuator solenoid, and a differential pressure sensor EGR (DPFE). These things work together to deliver the correct amount of recirculation based on engine temperature, load, etc. The P0401 code means that OBD detected an insufficient amount of EGR.

Causes A code P0401 most likely means one or more of the following has happened:
  • The DPFE (differential pressure feedback EGR) sensor is faulty and needs to be replaced
  • There is a blockage in the EGR (tube), most likely carbon buildup
  • The EGR valve is faulty
  • The EGR valve may not be opening due to a lack of vaccuum
Possible Solutions 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 noticable 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)
  • Replace the EGR valve
LOCATION:
drivers side of the engine bay, just under the intake manifold plenum where the throttle body bolts up! If you take the air snokel off you'll see it better! It has a remote mountted vaccum solenoid with a 2 wire connector going to it that you should be able to see near the throttle body.
Follow the hose from the solenoid down to the valve and you'll find it!

Code on diagnostics p0401


Code on diagnostics p0401:

What is going on?
Exhaust Gas recirculation low flow detected means that: there is vacuum problem in the EGR system - between the combustion chamber, EGR valve (mechanical - blown up diaphragm or clogged airlets/hoses) , EGR Modulator Valve (mechanical - blown up diaphragm, dirty EG/air filter or clogged airlets/hoses) and Vacuum Switching Valve ((mechanical - blown up diaphragm or clogged airlets/hoses OR electrical - VSV not properly synchronizing with the ECM, for instance).

Effects?
This causes the combustion chamber temperature to increase and produce Oxides of Nitrate (NOx) that is out of an acceptable emission range. This triggers the Malfunction Light (check engine light) to stay on (after a couple of driving cycles)!
Solution: Focus on EGR airways (hoses...) and organs (EGR valve, EGR Modulator, VSV), clean, check or replace the defected one. VSV seems to be criticale as it plays electrical & mechanical function. Once the repair is done, Clear the P0401 code using an OBII scanner.

P0401. P0133, P1131- emmision test


Based on what the tech manuals say I would change the DPFE sensor for the EGR Valve, careful not to tear the special silicone rubber hoses that go to it from the exhaust, as a Ford dealer tech I saw these codes allot, and the DPFE sensor was almost always the issue or the hoses going to it.
