There is a rational and purely financial reason for the high incidence of catalytic converters theft. Indeed, this anti-pollution device...
An internal combustion engine inevitably gets hot. The exhaust gases passing through the line can reach very high temperatures.
This pressure sensor takes the form of a small probe which, as its name suggests, allows temperature measurements to be taken on the exhaust gases.
In our cars, we have several filters that perform specific tasks. However, it is easy to get confused and it is best not to mix up the particulate filter with the cabin filter...
Before we go any further, I think it's good to understand more precisely the role of the lambda sensor. As the name suggests, it is indeed a sensor, a small one, found on the exhaust line, just before the catalytic converter.
The exhaust line includes various important components, such as the catalyst, possibly the diesel particulate filter, but also one or more silencers.
DPF, catalytic converter, lambda probe, SCR, silencer... Discover in this file a review of the history of the exhaust system from its beginning until today.
Catalytic converters and DPF theft affects all types of vehicles. But what are the reasons for this scourge ? Who benefits from the crime ?
Catalytic converters and DPF would be useless if they were not accompanied by a lambda sensor or a differential pressure sensor. A what ? If you don't know what we're talking about, it's time to get to know your exhaust system.
