The ABS or Anti-Lock Brake System ECU monitors the Wheel Speed Sensors rotational speed for anti-lock brake function, stability control and traction control. The ABS sensors report the speed of all four wheels to the ECU to determine if the wheels are locking up and to help provide safer stopping. Reasons for replacement include: ABS/brake lamp illumination, no or erratic ABS operation or problems with stability and or traction control systems.
The Vehicle Speed Sensor measures transmission, transaxle output or wheel speed. The engine control unit or ECU uses this information to modify ignition timing, air-fuel ratio, transmission shift points and to initiate diagnostic routines. A failing Vehicle Speed Sensor may lead to erratic shifting, inoperable speedometer, check engine light. The Vehicle Speed Sensor may be mounted in the transmission, transfer case or rear differential.

Symptoms of a Failing Speed Sensor vs. ABS Wheel Speed Sensor
Some vehicles may use the same part for both a Speed Sensor and an ABS Wheel Speed Sensor, while others may use two different parts. These parts serve different systems of the vehicle and may fail for different reasons - it is important to replace the proper sensor to fix the underlying issue.
SPEED SENSOR
The Speed Sensor(s) measure rotational speed of the transmission shafts. Common failure symptoms include:
Erratic Speedometer Behavior
Harsh or Improper Shifting
Loss of Cruise Control
Surging or Hesitation
Check Engine Light On
Located in 'Electrical'
ABS WHEEL SPEED SENSOR
The Anti-Lock Brake System (ABS) sensor monitors wheel speed. Common failure symptoms include:
ABS Light On
Brake Pulsing
No / Erratic Traction or Stability Control
No / Erratic ABS Operation
Braking Without Pedal Contact
Located in 'Brake & Wheel Hub'
