A passive wireless corrosion sensor is disclosed. A circuit is configured to provide a signal response when energized. An antenna is configured to wirelessly receive energy for energizing the circuit and to receive the signal response from the circuit and transmit the signal response. A corrosion sensitive connector interposes the circuit and the antenna. The corrosion sensitive connector conducts the energy from the antenna to the circuit and conducts the signal response from the circuit to the antenna when in a substantially non-corroded state. The corrosion sensitive connector creates an effectively non conducting link between the antenna and the circuit when in a substantially corroded state.
