Based on the description of the gauge for the reference height of the ABS solenoid valve core assembly, the utility model also provides a detection method for the reference height of the ABS solenoid valve core assembly, which is completed by using the gauge and comprises the following detection steps:

the method comprises the following steps: measuring the installation reference height of the to-be-detected ABS solenoid valve core assembly to be 14.9mm, and simultaneously determining that the reference height error of the to-be-detected ABS solenoid valve core assembly to be 14.9mm +/-0.05 mm; preparing a reference correcting block, wherein the installation reference height of the reference correcting block is the same as that of the ABS solenoid valve core component to be detected,
