1. A dynamic quantity sensor comprising:

  • a signal generating section for generating a detection signal having a signal level representing an applied dynamic quantity; and

    a signal correcting section for correcting said detection signal produced from said signal generating section in such a manner that an unapplied level of said detection signal to be obtained when said dynamic quantity is not applied is equalized to a predetermined reference level, wherein said dynamic quantity sensor has a failure mode in which an output of said signal generating section is fixed to said reference level, and said signal generating section adjusts the detection signal in such a manner that said signal correcting section generates a large correction amount sufficient for the output signal from said signal correcting section to deviate from a failure judgment unable region including said reference level in case of failure corresponding to said failure mode.
