A defect recognition device is provided for internal-combustion engines, as well as a process for operating an internal-combustion engine having at least two exhaust gas trains, with one lambda probe respectively being in each exhaust gas train. A joint measuring device detects the supplied air and a joint timing device apportions the fuel. The lambda probes, which generate a continuous signal for the lambda value of the exhaust gas, are used to provide improved defect recognition. The defect recognition device recognizes a defect when the signals supplied by the lambda probes deviate from one another.
