Latest vehicles are progressively built with new technologies, apart from the comfort of use it can bring, technology as well has the advantage of saving fuel or reducing the pollution emitted by our vehicles. This is exactly the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Chevrolet Bolt , this sensor as well named oxygen sensor plays an important purpose. To find out, first, we are going to find out what a lambda probe is used for, then, what are the lambda sensor problems on Chevrolet Bolt and how to fix them.
What is a lambda task on Chevrolet Bolt?
So we start our article with the benefit of a lambda sensor on Chevrolet Bolt , we will first discover what is the role of this probe and then how it functions.
Role of a lambda sensor on Chevrolet Bolt
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 Chevrolet Bolt , its objective is to control the amount of oxygen in the exhaust gases, this will enable the engine unit to change the air/fuel mixture to lower the pollution emitted by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Chevrolet Bolt
Before describing you the different problems of lambda probe on Chevrolet Bolt , we will look a little more in detail at its working to allow you to figure out exactly how it functions and thus to consider more serenely the correction of a problem associated with 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 measured 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 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 adjust the quantity of air and gasoline inserted into the engine unit to optimize the combustion .
Lambda sensor problem on Chevrolet Bolt
.
At last, we are now going to attack the section you are certainly most enthusiastic about this article, how to handle it if you have a lambda sensor problem on Chevrolet Bolt . 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 Chevrolet Bolt is HS
.
It is important to know that a lambda sensor has in general a lifetime of 150 000 km , this info can differ according to the year of your Chevrolet Bolt, your driving, and the good functioning of your engine unit. A poorly taken care of engine unit that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Chevrolet Bolt may be the engine unit light turns on, if you want to turn off the engine light of your Chevrolet Bolt, do not hesitate to visit our dedicated article to discover the process to stick to. The only effective technique to ensure that you have a lambda sensor problem on your Chevrolet Bolt and to pass your car to the diagnostic case, for that do not hesitate to consult our tutorial which explains you Chevrolet Bolthow to read the fault code of a Chevrolet Bolt. Please be aware that if you have problems with one of your lambda sensors, the just remedy to correct them will be to change the faulty sensor.
How to change a lambda sensor on Chevrolet Bolt?
And finally, we are going to concentrate on the correction of lambda sensor problems on Chevrolet Bolt , by explaining 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 know-how. 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 quickly. To replace it, it will be necessary to put your Chevrolet Bolt 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 Chevrolet Bolt.
