Part: Lambda sensor
Operation: How does a lambda probe work?

How does a lambda probe work? A 4-wire probe is composed of two elements: the first is the heating element, which is nothing more than a resistor, and the second is the reading element. Two wires are used for the probe's heater, while the other two are used for reading the exhaust gases. The heater is used to heat up the element that monitors the exhaust fumes as quickly as possible. So, if one of these probes were to be broken, how can we tell? The wires that deal with the probe's resistance are the red and white ones; we put the multimeter in continuity mode with the resistance reading: if it beeps and the resistance is very low, it means the probe is functioning. If, on the other hand, the probe is not working, we have an open circuit. This is the simplest way to check the lambda probe's heater.

How to reset the oil service in the Fiat Toro?

In this tutorial we can see how to reset the oil service in the Fiat Toro. Before carrying out this simple and quick operation, make sure that you have completed any required maintenance work. We start by inserting the key but leaving it in the initial position, after which we keep the accelerator pedal fully depressed and at the same time turn on the instrument panel. At this point, always keeping the accelerator pressed, press the brake pedal 5 consecutive times and, with the pedals in position, turn off the ignition. We check that the procedure has been successful by starting the vehicle.
