How to Replace the Lambda Sensor in the Toyota RAV4?

Model: Toyota Rav 4 Xa20, MK 2 - Years 2000-2006
Part: Oxygen sensor

As seen in this tutorial, replacing the lambda sensor in the Toyota RAV4 is a very simple and quick operation. Before proceeding, wait for the engine to cool completely. Start by opening the bonnet, then locate the sensor on the front side of the engine, right on the exhaust manifold. Next, disconnect the connector, unscrew the sensor using a 22 mm spanner if possible, or a standard spanner if not, and remove it from the hole. To install the replacement, simply follow the reverse procedure. If the sensor is difficult to unscrew, apply some penetrating spray and let it sit for a few minutes.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
