In a method of checking for a transposition of lambda sensors of a multicylinder internal combustion engine having at least two separate exhaust pipes connected to different cylinders, a catalytic converter arranged in each exhaust pipe, a lambda sensor arranged in each exhaust pipe upstream of the respective catalytic converter, a lambda sensor control circuit for each lambda sensor, and an air inlet connection associated with at least one exhaust pipe upstream of the respective lambda sensor, air is supplied to one of the exhaust pipes, and the signal provided by the respective Lambda sensor is compared with a stored threshold signal value to determine whether the lambda sensor installed is operative and is connected to the proper lambda sensor control circuit.
