Recent vehicles are progressively pre-loaded 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 vehicles. This is precisely the subject matter of our article content of the day, we are going to look at the problems of the lambda sensor on Chevrolet HHR , this sensor also known as 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 HHR and how to solve them.
What is a lambda role on Chevrolet HHR?
So we begin our content with the interest of a lambda sensor on Chevrolet HHR , we will first discover what is the job of this probe and then how it works.
Role of a lambda sensor on Chevrolet HHR
First created 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 HHR , its mission is to control the amount of oxygen in the exhaust gases, this will enable the engine to change the air/fuel mixture to decrease the pollution emitted by the motor vehicle and lower the car’s fuel consumption.
Lambda sensor procedure on Chevrolet HHR
Before explaining you the different problems of lambda probe on Chevrolet HHR , we will look a little more in detail at its functioning to allow you to figure out precisely how it works and thus to consider more serenely the correction of a problem related to it.
As we informed 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 only one lambda sensor required 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 interest 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 to improve the combustion .
Lambda sensor problem on Chevrolet HHR
.
At last, we are now going to attack the part you are obviously most interested in this content, what to do if you have a lambda sensor problem on Chevrolet HHR . In a first step we will see 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 HHR is HS
.
It is important to know that a lambda sensor has generally speaking a lifetime of 150 000 km , this info can differ according to the year of your Chevrolet HHR, your driving, and the good performance of your engine. A poorly taken care of engine that emits unburned gases may forever corrupt your lambda sensor. One of the clues that can alert you of a faulty lambda sensor on Chevrolet HHR may be the engine light turns on, if you want to turn off the engine light of your Chevrolet HHR, do not think twice to seek advice from our dedicated content to discover the procedure to stick to. The only effective way to make sure that you have a lambda sensor problem on your Chevrolet HHR and to pass your car to the diagnostic case, for that do not think twice to consult our guide which explains you Chevrolet HHRhow to read the fault code of a Chevrolet HHR. Please note that if you have problems with one of your lambda sensors, the only remedy to correct them will be to change the faulty sensor.
How to change a lambda sensor on Chevrolet HHR?
And finally, we are going to focus on the correction of lambda sensor problems on Chevrolet HHR , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite basic to accomplish 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 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 required to put your Chevrolet HHR 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 HHR.
