Wheel Speed Sensor: Initial Inspection and Diagnostic Overview
ESP
Front / Rear Wheel Speed Sensor On-Vehicle Inspection
Output Voltage Inspection
1. Disconnect negative (-) cable from battery.
2. Hoist vehicle a little.
3. Disconnect wheel speed sensor connector.
4. Set up measuring device as shown in figure, the resistance to 115 ohms and the power supply voltage to 12V
Caution:
Incorrect voltage and/or wrong connection cause damage to wheel speed sensor.
5. Measure voltage at resistance without wheel rotation. If voltage is out of specification, check sensor, mating encoder and their installation
conditions.
Voltage at the resistance (115 ohms) without wheel rotation
680-960 mV
6. Measure voltage at resistance with wheel rotation and confirm voltage alternately changes between high and low voltages. If voltage does not
change with wheel rotation, check sensor, mating encoder and their installation conditions.
