Toyota ABS Sensor Front LH

Description

Why do ABS sensors fail?

Given its position, the reluctor wheel or tone ring can easily become dirty or damaged. Similarly, dust can collect on the sensor. Both could result in an erratic, or even no signal at all. Other common causes of failure include:

• Breaks in wiring/sensor winding due to excessive vibration
• Internal short circuits
• Increased wheel bearing clearance
• Damage during replacement of other braking components
