BMW Serie 3 - Video tutorial

Model: BMW Serie 3 E36 - Years 1990-2001
Part: Lambda sensor
Operation: Lambda probe replacement in the flue gas circuit

The lambda probe is a sensor capable of controlling the polluted components of the exhaust gases to keep the mixture ratio (kg air / kg fuel) within the optimal efficiency range of the catalyst. The probe signal output is an electrical signal which is sent to the injector control unit. The lambda probe should be changed frequently especially if there is a loss of power, excessive consumption and polluting exhaust gases. An effective check of the four lambda probes is obtained with special equipment, however, it is possible to carry out a simple check using a good digital meter. Disconnect the probe connector and check the electrical resistance by measuring between the white and yellow cables. If the probe has a certain resistance it can be considered functioning otherwise the probe is interrupted. Check all four probes, two of which are in the exhaust manifold and two in the engine manifold. Due to high temperatures, replace the sensors with a very cold engine. Using a simple spanner, unscrew the probe and disconnect the connector. To be safe, replace all the probes, then run several kilometers and then do the test again with the appropriate equipment to verify that the polluting parameters have returned.

How do you adjust the clutch cable on the Kia Picanto?

To be able to adjust the clutch cable of the Kia Picanto you need to open the hood so that you have access to the components inside the engine compartment: in order to reach the cable you will need to remove some components on the right side, such as the battery and the air filter. Below them you will find the clutch cable, which will have to be adjusted by screwing or loosening the bolt placed at the end of the cable. This will make the pedal harder or softer; after the adjustment, it will be possible to assemble all the components by closing the hood.
