In this video we discussed the problem that a person faces after removing a faulty catalytic converter. In order for the engine management system to work correctly, we need to trick the second oxygen sensor so that it gives the required voltage to the ECU, for this we make an oxygen sensor emulator. And to the question of whether to install it, our answer is yes, it works. #car repair #catalytic converter #lambda probe #oxygen sensor #incorrect operation of the catalyst #emulator #for the garage #ECU #error #removedcatalytic converter
