Citroen C3 - Video tutorial

Model: Citroen C3 SC - Years 2009-2016
Part: Lambda sensor
Operation: How to replace the Lambda sensor on the Citroen C3

The task of the Lambda probe is to detect the concentration of oxygen inside the exhaust gases, in order to maintain the mixture ratio within the optimal efficiency range of the vehicle's catalytic converter. In this video, we see how to replace them on the Citroen C3, where there are two: one lower and one upper, and they are replaced between 80,000 and 100,000 km. Universal type probes from Bosch can be found online with the code B0068N1CQO on Amazon, priced at 51.90 each, with free delivery for Prime customers. With the hood open, we remove the red connector, but to remove the upper one, a special key is required, as we see in the video, but it is easily removed. In the same way, we insert the new one and reconnect the plug. To access the lower one, we need to go under the car, always disconnecting a plug from above, but the procedure is the same, as we see in the video. Here too, we reconnect the plug. Job done.
