Abstract
A method for testing a sensor within an electronic circuit. The sensor includes a first sensor element and a first reference element in a first branch, and a second sensor element and a second reference element in a second branch of the Wheatstone bridge circuit, which is in parallel with the first branch. The Wheatstone bridge circuit includes first and second inputs for first and second reference signals, respectively, which are each connected to the branches. The first branch includes a first signal output, and the second branch includes a second signal output between the second sensor element and the second reference element. The method includes: opening the first or second switch; applying a predefined first and/or second reference signal(s); and evaluating a first or second useful signal as to whether damage to the sensor or an electrical connection between the sensor and the electronic circuit exists.
