Abstract
A method of calibrating a position sensor in an automotive transmission having a transmission housing having mounted therein a casing (10) for the position sensor which includes a pressure member (14) movably supported in the casing (10), and an electrical displacement sensor (38) actuated by the pressure member (14) for measuring the position of the pressure member (14) relative to the casing (10), such that, after the casing (10) of the position sensor has been mounted in the transmission housing, the displacement sensor (38) is used for performing at least one calibration measurement for at least one gear position, and, for each gear position to be detected, a tolerance range for the corresponding measurement value of the displacement sensor is defined on the basis of the result of the calibration measurement.
