How Many Lambda Sensors Does the Fiat 500 Have and Where Are They Located?

Model: Fiat 500 - Years 2007-2022
Part: Oxygen sensor

In the Fiat 500, as in most recently manufactured vehicles, there are two lambda sensors in the exhaust system. As shown in this video, the first sensor is located inside the engine compartment, on the right side of the exhaust manifold when viewing the vehicle from the front. The second sensor is located underneath the vehicle, at the junction between the manifold and the single pipe. Replacing these sensors is very simple; it only requires a spanner and, if necessary, a penetrating spray. Always ensure the engine is completely cold when working.
