Check of catalytic converter and lambda probe

For this check the car is connected to a special tester in a workshop which can unpack at the same time received results of measurements in the form of check confirmation. If separate results do not reach the ordered indicators, you do not receive also any confirmation of check. But before you at unsuccessful check WITH decide on contents in favor of replacement of expensive detail, it is worth repeating check in other workshop. Despite the difficult measuring technique, at measurements a certain dispersion of results is possible. Sometimes it appears rather more or less long trip at which the engine, catalytic converter and a lambda probe reach full working temperature.
