Verification of correct operation of a physical parameter sensor

A method for sensing a physical parameter and for verifying correct operation of a system used for sensing the physical parameter, the method comprising:

• sensing a physical parameter via a sensing device including four resistive elements configured in a Wheatstone bridge configuration having two biasing nodes and two sensing nodes, at least one of the four resistive elements comprising a sensing transducer having a resistance that varies in response to variations of a parameter value of the physical parameter;
• selectively providing, via a biasing network, first and second biasing conditions to the sensing device via the first and second biasing nodes, the first and second biasing conditions configured to cause first and second output electrical signals generated at the two sensing nodes of the Wheatstone bridge in response to the first and second biasing conditions, respectively, selectively provided to the sensing device to be different from one another;
• determining consistency of the first and second output electrical signals, the first and second output electrical signals indicative of the parameter value of the physical parameter, wherein consistency between the first and second output electrical signals is determined if the first output electrical signal is within a consistency range defined by a predetermined delta of a non-zero predetermined offset from the second output electrical signal;
• and
• verifying, via a verification module, correct operation of the system based on the consistency determined.
