Latest vehicles are progressively equipped 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 released 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 Acura TL , this sensor as well named oxygen sensor plays an essential purpose. To find out, first, we are going to identify what a lambda probe is employed for, then, what are the lambda sensor problems on Acura TL and how to fix them.

What is a lambda purpose on Acura TL?

So we begin our article with the interest of a lambda sensor on Acura TL , we will first see what is the role of this probe and then how it works.

Role of a lambda sensor on Acura TL

First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission standards. As well called oxygen sensor on Acura TL , its task is to regulate the amount of oxygen in the exhaust gases, this will enable the engine to adapt the air/fuel mixture to decrease the pollution released by the car and lower the car’s fuel consumption.

Lambda sensor process on Acura TL

Before describing you the different problems of lambda probe on Acura TL , we will look a little more in detail at its operation to allow you to discover exactly how it works and thus to consider more serenely the correction of a problem associated with it.
As we explained to you, a lambda probe has the task of controlling the amount of oxygen present in the exhaust gases . One could naively believe 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 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 modify the quantity of air and gasoline injected into the engine to optimize the combustion .

Lambda sensor issue on Acura TL

.
At last, we are now going to attack the part you are certainly most keen on this article, how to proceed if you have a lambda sensor issue on Acura TL . 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 Acura TL is HS

.
It is essential 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 Acura TL, your driving, and the good performance of your engine. A poorly maintained engine that releases unburned gases may completely corrupt your lambda sensor. One of the clues that can warn you of a faulty lambda sensor on Acura TL may be the engine light comes on, if you want to turn off the engine light of your Acura TL, do not hesitate to visit our dedicated article to see the procedure to follow. The only effective technique to ensure that you have a lambda sensor issue on your Acura TL and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our guide which explains you Acura TLhow to read the fault code of a Acura TL. Please note that if you have problems with one of your lambda sensors, the only solution to correct them will be to change the faulty sensor.

How to change a lambda sensor on Acura TL?

And finally, we are going to focus on the correction of lambda sensor problems on Acura TL , by detailing how to replace a lambda sensor.

The replacement of a lambda sensor is quite very easy to accomplish and you will have the ability to do it yourself with a minimal 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 fairly quickly. To replace it, it will be required to put your Acura TL 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 Acura TL.
