Latest vehicles are more and more built with new technologies, apart from the comfort of use it can provide, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject of our article content of the day, we are going to look at the problems of the lambda sensor on Mitsubishi Lancer , this sensor as well named oxygen sensor plays an necessary role. To find out, first, we are going to find out what a lambda probe is employed for, then, what are the lambda sensor problems on Mitsubishi Lancer and how to solve them.

What is a lambda fonction on Mitsubishi Lancer?

So we start our content page with the benefit of a lambda sensor on Mitsubishi Lancer , we will first discover what is the function of this probe and then how it functions.

Role of a lambda sensor on Mitsubishi Lancer

First developed by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. As well called oxygen sensor on Mitsubishi Lancer , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to lower the pollution emitted by the motor vehicle and lower the car’s fuel consumption.

Lambda sensor process on Mitsubishi Lancer

Before explaining you the different problems of lambda probe on Mitsubishi Lancer , we will look a little more in detail at its working to allow you to figure out precisely how it functions and thus to consider more serenely the correction of a problem related to it.
As we told you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively think that this data is determined upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was only one lambda sensor needed before the catalyst, but with the arrival of more drastic requirements there are now 2 lambda sensors, one before and one after the catalyst . The benefit is to have more exact data by compiling the two probes. These data are sent to the ECU which will modify the quantity of air and gasoline inserted into the engine to improve the combustion .

Lambda sensor problem on Mitsubishi Lancer

.
Finally, we are now going to attack the section you are obviously most enthusiastic about this content page, how to proceed if you have a lambda sensor problem on Mitsubishi Lancer . In a first step we will find out how to find a lambda sensor HS and in a second step how to change it.

How to know if a lambda sensor on Mitsubishi Lancer is HS

.
It is necessary to know that a lambda sensor has generally a lifetime of 150 000 km , this data can differ according to the year of your Mitsubishi Lancer, your driving, and the good working of your engine. A poorly looked after engine that emits unburned gases may completely damaged your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Mitsubishi Lancer might be the engine light turns on, if you want to turn off the engine light of your Mitsubishi Lancer, do not think twice to visit our dedicated content page to discover the procedure to stick to. The only effective technique to ensure that you have a lambda sensor problem on your Mitsubishi Lancer and to complete your car to the diagnostic case, for that do not think twice to consult our tutorial which explains you Mitsubishi Lancerhow to read the fault code of a Mitsubishi Lancer. Take note that if you have problems with one of your lambda sensors, the only remedy to resolve them will be to change the faulty sensor.

How to change a lambda sensor on Mitsubishi Lancer?

And finally, we are going to focus on the correction of lambda sensor problems on Mitsubishi Lancer , by describing how to replace a lambda sensor.

The replacement of a lambda sensor is quite simple to perform and you will have the ability to do it yourself with a minimum of tools and mechanical expertise. A lambda sensor is worth between 25 and 50€ , it is better to change the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is faulty the second one risks to drop you fairly quickly. To replace it, it will be necessary to put your Mitsubishi Lancer on candles and at the level of your catalyst unscrew your probes, disconnect them, reconnect them and screw the new ones . Once re-connected, you should not have any more problems with your lambda sensor on Mitsubishi Lancer.
