You’ve probably already heard of the famous EGR valve, the anti-pollution valve. It is not usually appreciated by drivers because it tends to create more trouble than anything else… In truth, dependent on the use you are going to make of your automobile, it can become congested and bring about you a lot of problems. If this is the case, you are probably wondering how to clean the EGR valve of your Mitsubishi Lancer ? Don’t worry, we’ve made this content to help you with this procedure. To do so, we will initially look at the goal of the EGR valve, then what are the failures that the EGR valve of your Mitsubishi Lancer can provoke and finally the part that will probably interest you the most, how to clean the EGR valve Mitsubishi Lancer?
How to Clean your Mitsubishi Lancer EGR Valve: Role and Operation
Purpose of the EGR valve
The EGR valve of your car has been integrated to diesel engines mostly to reduce pollution emitted by automobiles and to match EURO specifications on Mitsubishi Lancer . It will consequently influence the quality of exhaust gas output and get rid of toxic particles, mainly Nitrogen Oxide.
Operation of the EGR valve
Before we learn how to clean the EGR valve on your Mitsubishi Lancer , we will have a look at how it functions. As described just before, its task is to clean the exhaust gases, so it will be located at the engine outlet, thanks to a valve, it will be able to return the unburned exhaust gases to the engine for a second burn which will get rid of all unburned toxic particles. It will run mostly at low speed because at high speed the combustion is sufficient to burn all these gases.
How to clean your Mitsubishi Lancer EGR valve: Identifying faults
The EGR valve, despite the fact very effective to limit the pollution emissions of your Mitsubishi Lancer , will unfortunately tend to clog up because of soot/gas deposits that will accumulate in its mechanism, which will finally risk blocking the operation of the valve, until entirely blocking the engine, here are the symptoms that a faulty EGR valve on your Mitsubishi Lancer can provoke:
- Motor light on
- Power loss
- Technical assesment rejected
- Black gases
- Automobile that grazes at low speed
- Low RPM settings
How to clean your Mitsubishi Lancer EGR valve: In practice
And now we’ll start the part you are most interested in, how to clean the EGR valve of your car. Here are the two techniques that you can use.
Do it yourself
How to clean your Mitsubishi Lancer EGR valve system: Without dismantle
Although this approach is less effective, it is however possible to consider a “rough” cleaning of your EGR valve, in fact, you will only need to use fuel additives, similar to the products used to clean the injection. These specific solutions must be injected into the running engine, at the right operating temperature, diluted in about 20 litres of fuel and run the engine for 3 or 4 minutes in high rev to clean the EGR valve of your Mitsubishi Lancer.
How to clean your car EGR valve: With disassembly
Here is the strongest approach, which will require sufficient access to the EGR valve to perform the treatment yourself. If so, the procedure is fairly easy.

To make this happen, you will need to use a product such as solvent, petrol, oven cleaning product, which you will leave to act for ten minutes, then scrape off the rest using a scraper, finish cleaning with wire brush. If you want to go further, you can even clean the two conduits on which it is connected which may be scorched, for this, use a scraper and a vacuum cleaner to avoid dropping deposits in the conduits. You will only have to reassemble it and you will have finished cleaning the EGR valve of your Mitsubishi Lancer.
Have it done by a professional
If, your EGR valve is not reachable because of the series or the engine of your car and if removing it would cause too many problems (removing too many auto parts that hinder access for example), how to clean the EGR valve of your Mitsubishi Lancer? In this instance, it would be better rather than launching yourself into an overly complex procedure, you turn to an auto mechanic. He will be able to accomplish the job more cleanly and will be able, if necessary, to change the valve if it is dead.

Remove the EGR valve of your Mitsubishi Lancer
At last, some people make a more radical decision to limit the risk of a failed valve. Instead of cleaning the EGR valve of their Mitsubishi Lancer, they just choose to block it in the closed position. This treatment will have the effect of greatly increasing the pollution emitted by the automobile, of no longer complying with pollution requirements, of having an engine warning light all day on and ultimately risk fouling the engine. We strongly advise against making this choice. If you have other questions or want to learn more about your car, don’t think twice to take a look at our dedicated page.
