ABS sensor switch OE 31423609 Auto parts ABS wheel speed sensor for Volvo

Product Description:

ABS sensor switch

OE numbers: 31423609

Applicable vehicle type: For Volvo

The ABS sensor switch (commonly referred to as the 'ABS wheel speed sensor' or 'ABS sensor switch') is the signal source of the ABS anti-lock braking system, responsible for converting wheel speed into electrical signals to inform the ECU in real-time which wheel is approaching lock-up, so that braking force can be quickly adjusted.

Core functions:

• Real-time monitoring of wheel speed, calculation of slip rate, and prevention of brake lockup.
• Provides directional signals, supports hill hold control (HHC), automatic parking, and other advanced features.
• Provides reference vehicle speed for systems such as EBD, ESP, TCS, and iTPMS (indirect tire pressure).

Indications of failure and rapid diagnosis:

• The ABS/ESP/tire pressure light remains on, storing fault codes C0031-C0034.
• Signal loss during cold start or low speed → check air gap, missing teeth on the tooth ring, iron filings on the magnetic ring.
• Incorrect direction signal → sensor or magnetic ring installed incorrectly, simply swap the installation position.
