How to replace the lambda sensor on Toyota Yaris 1

Model: Toyota Yaris Xp10 - Years 1999-2005
Part: Oxygen sensor

In this video, we will see how to replace the lambda sensor on the Toyota Yaris MK1: we will need to lift the vehicle, as the work needs to be done from underneath, around the middle of the vehicle's frame. Here we will find, corresponding to the horizontal bar, an electrical connector to disconnect, clean the area well with a metal brush and then lubricate the sensor's attachment with WD-40: let it act and then remove it with a specific key. Lubricate the part again and then take the new sensor, which we will place in its position with our key, tightening it to 41 Nm; spray the electrical connector with WD-40 and put it back in place: we can lower the vehicle.

How to change the time on a Toyota Yaris

In this video we see how to change the time on a Toyota Yaris, specifically when it comes to switching from daylight saving time to standard time and vice versa. We go to the multifunction screen and press "settings": from there we go to press the clock, simply click on daylight saving time, and the clock will change the time for us, without doing anything else. All we want to do is just adjust the time format to 12 or 24 hours, as is customary in the area where we live: for example in Anglo-Saxon countries it is common to set the time to 12 hours, while in the European Union it is normally set to 24 hours.
