Modern vehicles are progressively pre-loaded with new technologies, apart from the comfort of use it can provide, technology also has the advantage of saving fuel or reducing the pollution released by our vehicles. This is precisely the subject matter of our article of the day, we are going to look at the problems of the lambda sensor on Acura TSX , this sensor also called oxygen sensor plays an important role. To find out, first, we are going to identify what a lambda probe is utilized for, then, what are the lambda sensor problems on Acura TSX and how to solve them.
What is a lambda role on Acura TSX?
So we start our article with the interest of a lambda sensor on Acura TSX , we will first see what is the role of this probe and then how it functions.
Role of a lambda sensor on Acura TSX
First produced by Volvo in the 1970s, it began to show up on our cars in the 1990s with the first EURO 1 emission requirements. Also called oxygen sensor on Acura TSX , its mission is to control the amount of oxygen in the exhaust gases, this will allow the engine unit to modify the air/fuel mixture to lower the pollution released by the car and lower the car’s fuel consumption.
Lambda sensor process on Acura TSX
Before describing you the different problems of lambda probe on Acura TSX , we will look a little more in outline at its functioning to allow you to understand precisely how it functions and thus to consider more serenely the correction of a problem associated with it.
As we informed you, a lambda probe has the job of managing the amount of oxygen present in the exhaust gases . One could naively presume 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 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 adapt the quantity of air and gasoline injected into the engine unit to improve the combustion .
Lambda sensor problem on Acura TSX
.
At last, we are now going to attack the section you are obviously most enthusiastic about this article, what to do if you have a lambda sensor problem on Acura TSX . In a first step we will see how to identify a lambda sensor HS and in a second step how to replace it.
How to know if a lambda sensor on Acura TSX 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 Acura TSX, your driving, and the good performance of your engine unit. A poorly looked after engine unit that releases unburned gases may permanently corrupt your lambda sensor. One of the clues that can warn you of a defective lambda sensor on Acura TSX might be the engine unit light turns on, if you want to turn off the engine light of your Acura TSX, do not hesitate to visit our dedicated article to see the procedure to stick to. The only effective technique to ensure that you have a lambda sensor problem on your Acura TSX and to complete your car to the diagnostic case, for that do not hesitate to seek advice from our tutorial which explains you Acura TSXhow to read the fault code of a Acura TSX. Please be aware that if you have problems with one of your lambda sensors, the just remedy to solve them will be to replace the defective sensor.
How to replace a lambda sensor on Acura TSX?
And finally, we are going to focus on the correction of lambda sensor problems on Acura TSX , by describing how to replace a lambda sensor.
The replacement of a lambda sensor is quite simple to carry out and you will be able 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 replace the 2 lambda sensors present upstream and downstream of your catalytic converter because if one of them is defective the second one risks to drop you quickly. To replace it, it will be necessary to put your Acura TSX 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 TSX.
