When do I blank off the EGR valve?
The engine code may need to be reset. After 3-5 times of switching the car on and off, the code should reset by itself if the original fault is fixed, but not always. I personally blank off EGR valves to prevent damage to the butterfly valves on the inlet manifold.
Are there any problems with the EGR system?
Other problems with EGR include: worse economy, (forcing the car to burn more fuel and create more CO2 pollution in order to reduce NOx emissions), dirty intake mixing with fuel to clog up your intake manifold and stop your sensors reading correctly, dirty mixture in the cylinder head adding particles to the sump oil… It really is a STUPID idea!
How does the EGR valve work in an engine?
The EGR valve recirculates a small amount of exhaust into the combustion cycle. The warmth of the exhaust lets the combustion chambers warm up quickly, while the spent, inert gases keep the chambers from getting too hot when the engine fully warms up.
How often should I Clean my EGR valve?
Read your owner’s manual for specific maintenance schedules, but you can generally inspect your EGR valve every 12,000 to 15,000 miles (19,000 to 24,000 km). If you clean your EGR valve and it seems to get clogged sooner, have your mechanic run a diagnostic. Your engine may need a more thorough tune-up to be creating so much carbon so quickly.

Where is the entry port for the EGR valve?
Clean out the entry port. The entry port is where the valve tubes connect to the engine (usually the intake manifold) while the EGR valve is off. Reinstall the EGR valve.
What happens when you have a Clogged EGR valve?
A car with a clogged EGR valve has a tendency to cough and sputter while idling. On rare occasions, a clogged EGR valve cause your engine to make a knocking or popping noise. This can occur when the EGR valve is stuck in the closed position and gases build up in your motor. Engine Light Help: Help With Those Troublesome EGR Valve Codes!
What’s the code for an EGR valve throw?
What code will an EGR valve throw have? The P0401 trouble code is related to your car’s exhaust gas recirculation (EGR) system, which controls an engine and reduces emissions. Suppose a computer-controlled valve gives a certain amount of gases back into your engine to be burnt with the air-fuel mixture.
What can I use to clean an EGR valve?
This is a home experiment and an unbiased use of JLM Diesel Air Intake & EGR Cleaner. Similar products are available. This product is designed to dissolve carbon deposits, gum and varnish build up. It should restore air flow to the engine thus improving power and acceleration while reducing exhaust smoke.
What should resistance reading be for EGR valve?
For an electric EGR valve, you need to have a multimeter; this device will be used to do a resistance reading, referred to as an ‘ohms test.’ Once connected, you should see a reading of about 20 to 24 ohms. You can check the repair manual of your vehicle for this.
Why does my engine stall when the EGR is open?
This is because the temperature is lower so fuel does not burn at the optimal temperature and as a result is less efficient. Stalling when the engine idles like a rough idle is usually caused when the EGR valve is permanently open and is constantly letting exhaust gases into the EGR system.
How can I tell if the EGR solenoid is working?
With the ignition on and engine off, use a scan tool to activate the EGR solenoid. Listen or feel for a clicking, indicating that the solenoid is operating. If the solenoid does operate, you’ll have to check current draw on the ground circuit.
How does an EGR valve work on a diesel engine?
When you slowly and efficiently come to a stop, the valve also closes and stops the flow of exhaust gases. The process continues so long as the engine is operating. Once you shut off the engine, the valve also closes and stays in that position. Diesel and gasoline-powered engines can use an array of EGR valve configurations.
When did common rail diesel start using EGR?
Common Rail Diesel vehicles and has their own solution. that. So, what is it? engine from the early 2000’s onwards (in Australia). All vehicles must comply with ADRs (Australian allow access to the Australian market. The EGR is employed to reduce the amount of NOx (Nitrogen (Diesel).
What do you need to know about the EGR system?
First and foremost, the EGR system is a form of emissions control equipment, fitted to a modern diesel engine from the early 2000’s onwards (in Australia). All vehicles must comply with ADRs (Australian Design Regulations) and emission outputs are a critical part of the criteria manufactures must meet to
Can you clean an EGR valve without removing it?
If you cannot get direct access to the turbo an alternative would be to spray (less effective) into the air duct in the direction of the turbo but please remember to remove the MAF (mass airflow)/air intake sensor first as the cleaner may damage it.

Why does my EGR make a Claggy mess?
Makes an almighty claggy mess that is hard to clean up! The same goes for your motor when the PCV Valve and EGR System get together and decide to have a party like two naughty kids and cause mischief without you knowing. Valve, causes a claggy, sticky, build-up of Carbon that eventually solidifies over time.
