The present invention refers to a vapor space anticorrosive composition comprising corrosion inhibitors, surfactants and possibly thickeners, wherein one surfactant is selected from alkylamine ethoxylates, and being useful as an engine run-in composition and as a coolant. The sensor has a base which extends into a bore formed in the valve body. A first gate structure is formed on part of the substrate located in the active areas and, simultaneously, a second gate structure serving as a dummy gate structure is formed on the substrate located in the isolation area.
