Wheel Speed Sensor

This article has been updated by technical service bulletin (TSB) 05-50-008 dated August 2005.

The 2006 Sonata Shop Manual (page BR-79) contains incorrect information for the wheel speed sensor power supply circuit inspection diagram.
The correct terminal is terminal 1.
Terminal 2 is the signal wire.

Connect an ohmmeter between the wheel speed sensor terminals and measure the resistance.
Service standard
Front: 1,240 - 1,460 Ohms
Rear: 1,240 - 1,460 Ohms

Output voltage
When measuring with an oscilloscope: Min. 120mVp.p (at 2.75 Km/h)






Note:
- Voltage to terminal 1 will be approximately zero if a DTC code is set for the wheel speed sensor being tested.
- The voltage between terminal 2 and chassis ground will fluctuate between a high of 0.89 ~ 1.26V and a low of 0.44 ~ 0.63V.
