03 honda civic 1.7L p0401 EGR code.


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)

Start the engine, then shuts off directly, could not run the negine


Check your "anti shudder valve". It's a flapper on your EGR valve. Very common problem on these.

2003 GMC Sierra is running rough. What can cause this problem? This problem just recently started and it occurs when I first accelerate from zero to lets say 25 or 30 mph. As I progressively increase speed...


Find the egr valve and with the engine running, disconnect the vacuum line attached to it. If the engine runs better then the egr valve is stuck open. Replace the egr valve. It is held in by 2 bolts and usually located at the front of the intake manifold. Usually dull gold in color and shaped like a mushroom.

Check engine light is on. I was told it is the EGR. How do I locate the EGR on this vehicle? The code is P004. 2002 Chevy Express with 5.7 ltr. engine.


http://www.autoguide.net/apf/chevy-engine_parts/express_2500-2002-air_intake-b7010_148259del.html well it should be near the front of the intake manifold, you will see the EGR valve ( which looks like the thing on the web site link). Disconnect the electrical connector, remove the two 10 mm head bolts, remove the lead coated gasket from the intake. Be sure to clean the surface of all evidence of the gasket, using care to not get any into the intake. Place the new gasket on the EGR valve, using the bolts to keep it in place, put the new EGR on the intake. Tighten the bolts up evenly, plug the connector back in, hope this helps

ASSUMING YOU HAVE A 3.4L ENGINE, YOU NEED TO REMOVE THE EGR VALVE AND THE THROTTLE BODY. RUN A PIECE OF A HANGER THROUGH THE EGR PORT AND REMOVE THE CARBON PARTS THROUGH THE THROTTLE BODY.

Your car goes in "limp mode"!!!
If you scan the EDC-15P engine control unit with a VAG or KTS -BOSCH diagnosis tool you will find this:
"Fault code: P1557 - Turbo Boost pressure control exceeded"
You must try follows if you are able to do this:
1. Engine stopped and ignition switch off. Check all pneumatic connections and hoses between turbocharger actuator = pressure unit for boost-pressure control, boost-pressure control solenoid valve, vacuum reservoir, EGR control solenoid valve, intake-manifold flap solenoid valve, EGR valve with throttle - part of intake manifold. Also the vacuum connection between tandem pump and brake booster. If you find something wrong replace parts. If not go to step 2.
2. Extract the hose of the turbocharger actuator = pressure unit for boost-pressure control part of turbocharger. Instead of the original hose you must place another 1 meter long hose with the same inside diameter, and then you check to inspire yourself the air from the other one extremity of this hose. The mechanical connecting rod of the turbocharger actuator must have a smooth and whole motion. If you can do that with your mouth, then you must replace the boost-pressure control solenoid valve. If you can not reach this with your mouth, then you go to step 3.
3. This is the most difficult work. The problem is that the soot particles deposits inside the turbocharger plugging the variable nozzle geometry mechanism = adjustable vanes of the turbine. If the turbocharger actuator is not able to adjust the turbine vanes the charge air pressure increase too much and ECU (engine control unit) go in "limp mode" = engine protection software. As a result the "limp mode" engine still running until you turn the engine off (ignition switch off) and back on when the "limp mode" is deactivated, but the fault ("Fault code: P1557 - Turbo Boost pressure control exceeded") still remain in ECU memory !!!
4. You must be able to extract the turbo from the engine and then to disassemble the turbocharger, clean inside adjustable vanes mechanism and refit all.
It is some work to do here, but after that you will be full satisfied! NO MORE "LIMP MODE"!!!

2005 Golf TDI Diesel - EGR "Emissions workshop" fault light


Hi, The EGR valve itself is on a set of flexible pipework - usually stainless steel - which runs between the inlet manifold and the exhaust manifold. The EGR actuator valve is pneumatically / vacuum operated by a solenoid valve, controlled by the ECU ( aka the brane). It's not usual for the EGR valve itself to fail, more likely the solenoid valve or its electrical connector getting dirty. If you google for VAG TDI N75 valve you should get all the info you could possibly ever need :-)

Hope this helps, D.
