A method (400) of verifying operation of at least one wind turbine sensor (204) includes dynamically defining a neighborhood (306) of neighbor wind turbines (100) for a first wind turbine (308), each neighbor wind turbine including at least one sensor. The method also includes receiving data from at least one neighbor wind turbine sensor and determining a status of at least one sensor of the first wind turbine using the data received from the neighbor wind turbine sensor. Data from neighbouring wind turbines can be normalized by forming a weighted combination of these data. The normalized data are compared with data delivered by the sensor to be tested, to determine a faulty sensor. A defect sensor can be replaced by a virtual sensor giving an estimated value based on sensor outputs from neighboring wind turbines.
