What This Sensor Helps Address

• ABS warning light caused by a failed rear wheel speed sensor
• Erratic or missing wheel speed signal at the rear left wheel
• ABS system fault codes related to wheel speed input
• Brake system performance issues tied to inaccurate sensor readings
• Intermittent braking control concerns from damaged sensor wiring or connector wear

Installation Notes

Install at the rear left wheel position on compatible 2012-2016 Hyundai Elantra vehicles. Verify connector shape, terminal count, and harness routing before installation. Inspect the tone ring, wheel hub area, and wiring path for damage or contamination that could affect signal quality. Follow the included instruction sheet and confirm the sensor is seated and secured correctly before clearing ABS fault codes.

Quality Assurance

Delphi tests and calibrates its sensors to OE standards and uses product validation methods during development. That focus on signal accuracy helps support reliable ABS operation and reduces repeat repairs.
