How to clean the upper lambda probe

Model: (Various brands) Various
Part: Oxygen sensor

Video tutorial

In this video we can see the responsibilities of the Lambda probe, in case our car jerks a bit: through the sensors with which the car is equipped, the engine understands if the air in the circuit is sufficient for correct "fueling", and when the sensors called "lambda probes" that are input and output to the catalytic converter do not read correctly then the engine also does not work well.

To access the probes, special keys are needed, which we can find for example on Amazon with the code B01MDOQUXX at the price of 10.99 euros, free delivery for Prime customers.

To remove the upper one, we must disconnect the connector and then remove it with the appropriate key, and we see that it is quite dirty; cleaning it is simple, just a brush with not too hard bristles. Reassembling it is equally simple: reposition it in its place, without tightening it to death and reconnect the electrical connector.
