The invention discloses a method for testing the performance of a camshaft phase sensor. The method comprises: installing a first signal target wheel and a second signal target wheel on a rotating shaft connected with a motor; installing a standard sample fixing cantilever and a tested sample fixing cantilever on a fixing shaft; installing a sensor standard member on the standard sample fixing cantilever for testing the rotating phase of the first signal target wheel; installing a sensor detecting member on the tested sample fixing cantilever for testing the rotating phase of the second signal target wheel; connecting the sensor standard member and the sensor detecting member with an oscilloscope; driving the rotating shaft to rotate by using the motor in order that the first signal target wheel and the second signal target wheel synchronously rotate; displaying the waveform of a standard sample on the oscilloscope by means of the rotating phase of the first signal target wheel; displaying the waveform of a tested sample on the oscilloscope by means of the rotating phase of the second signal target wheel; comparing the waveform of the standard sample with the waveform of the tested sample so as to determine the performance of the tested camshaft phase sensor. The method is visualized in decision, high in test efficiency, and good in test accuracy.
