For many sensors especially critical ones there are multiple independent ones (like indicated airspeed). If they deviate there are standard procedures to determine which one(s) are faulty. For IAS you basically set a determined thrust at a determined pitch. Then you have a table which gives you IAS for the altitude you are at. This will determine the faulty pitot tube. I think for other sensors there are similar procedures.
