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'
