Recent cars are more and more furnished with new technologies, apart from the comfort of use it can bring, technology also has the advantage of saving fuel or reducing the pollution emitted by our cars. This is precisely the subject matter of our article content of the day, we are going to look at the complications of the lambda sensor on Chevrolet Equinox , this sensor also called oxygen sensor plays an essential purpose. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor complications on Chevrolet Equinox and how to fix them.
What is a lambda task on Chevrolet Equinox?
So we start our article with the interest of a lambda sensor on Chevrolet Equinox , we will first discover what is the function of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Equinox
First produced by Volvo in the 1970s, it began to appear on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Chevrolet Equinox , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to modify the air/fuel mixture to lower the pollution emitted by the car and lower the car’s fuel consumption.
Lambda sensor operation on Chevrolet Equinox
Before explaining you the different complications of lambda probe on Chevrolet Equinox , we will look a little more in detail at its operation to allow you to discover precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the job of controlling the amount of oxygen present in the exhaust gases . One could naively think that this data is calculated upstream of the combustion but it is on the contrary measured at the engine outlet . With the EURO 1 standard there was just one lambda sensor required before the catalyst, but with the arrival of more drastic standards there are now 2 lambda sensors, one before and one after the catalyst . The interest is to have more exact data by compiling the two probes. These data are sent to the ECU which will adapt the quantity of air and gasoline injected into the engine unit to optimize the combustion .

.
At last, we are now going to attack the section you are absolutely most keen on this article, how to handle it if you have a lambda sensor problem on Chevrolet Equinox . In a first step we will find out how to locate a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Chevrolet Equinox is HS
.
It is essential to know that a lambda sensor has generally a lifetime of 150 000 km , this statistics can vary according to the year of your Chevrolet Equinox, your driving, and the good working of your engine unit. A poorly maintained engine unit that produces unburned gases may permanently damaged your lambda sensor. One of the clues that can notify you of a faulty lambda sensor on Chevrolet Equinox may be the engine unit light turns on, if you want to turn off the engine light of your Chevrolet Equinox, do not think twice to seek advice from our dedicated article to discover the procedure to follow. The only effective technique to be certain that you have a lambda sensor problem on your Chevrolet Equinox and to pass your car to the diagnostic case, for that do not think twice to seek advice from our tutorial which explains you Chevrolet Equinoxhow to read the fault code of a Chevrolet Equinox. Take note that if you have complications with one of your lambda sensors, the just solution to solve them will be to replace the faulty sensor.
How to replace a lambda sensor on Chevrolet Equinox?
And at last, we are going to concentrate on the correction of lambda sensor problems on Chevrolet Equinox , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to execute and you will be able to do it yourself with a minimal of tools and mechanical expertise. A lambda sensor is worth between 25 and 50€ , it is better to replace 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 quickly. To replace it, it will be required to put your Chevrolet Equinox 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 complications with your lambda sensor on Chevrolet Equinox.
