How to Replace the Lambda Sensor of the Fiat Punto?

Model: Fiat Punto MK 2, 188 - Years 1999-2011
Part: Oxygen sensor

Replacing the lambda sensor in the Fiat Punto is straightforward; let's see how to proceed in this tutorial for the 1.2 petrol engine version. First, remove the cover of the exhaust manifold by unscrewing the 4 upper fixing bolts using a 5mm hex key and a 10mm socket. Next, unscrew the remaining 2 lower bolts. Once the cover is removed, disconnect the sensor connector and unscrew it from the manifold, spraying WD40 on the threads if necessary. Finally, install the replacement part by following the reverse procedure.
