Essential Speed Signal Device

🚗 This critical component monitors how fast your wheels spin, sending accurate speed information to your vehicle’s onboard computer. The car relies on this data to control functions such as gear shifting, ABS braking, and cruise control.

Why Is This Part Important?

• Enables smooth and timely gear changes
• Supports anti-lock braking system (ABS)
• Assists traction and stability control
• Ensures accurate speed readings on dashboard

How Does It Work?

The sensor detects wheel rotation using magnetic or hall-effect technology, generating signals sent to the ECU (engine control unit). The ECU calculates speed and adjusts various systems for safe operation.

Problems When Broken

• Erratic or non-working speedometer
• Transmission shifting issues
• ABS warning lights and limited braking
• Cruise control failure
