A method of calibrating an acceleration sensor by utilizing a two point analysis involves positioning the acceleration sensor at a first angle, measuring a first output voltage and positioning the sensor at a second angle and measuring a second output voltage and thereafter calculating a sensitivity ratio and a zero position output voltage based on the angles and voltages. Further, the method of the present invention optionally includes a second calibration after the acceleration sensor is installed onto a vehicle. Thus, the present invention improves accuracy in determining actual vehicle acceleration.
