ABS WHEEL SPEED SENSOR TESTING How To Test ABS Wheel Speed Sensor Use your trusty multimeter to check continuity through wheel speed sensors. This sensor has a value of about 1.5 K ohms. AC VOLTAGE With the meter set to AC voltage, spin the wheel by hand. The sensor should produce between .5 to 1 volt of AC current. The faster the wheel is spun, the more voltage is produced. BIAS VOLTAGE PASSIVE  SENSORS Some vehicles will send a DC voltage to the sensor through the ground wire. The signal will ride up on the DC signal. This is done so that the sensor can be tested by the ABS system without the vehicle moving. These types of vehicles will set WSS codes the moment the key is turned on. You can clear a WSS code and the moment the key is turned on, the code will immediately be back. The ABS computer is looking at the voltage coming back from the sensor. High resistance or an open circuit can be immediately detected. Often, with these systems the troub...
