OE-Style Sensor Performance

Delphi develops and validates its vehicle sensors using OE-focused methods, and this ABS wheel speed sensor is tested and calibrated to OE standards for accurate readings. That level of signal consistency matters on rear-wheel speed inputs for vehicles like the Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon, where the ABS module relies on clean data for braking and traction control operation. Cross-reference part numbers for the same application include Standard Ignition ALS2651.

Common Issues This Sensor Can Address

• ABS warning light triggered by a faulty rear wheel speed signal
• Intermittent traction control or stability control faults
• Erratic or missing wheel speed data from the rear axle
• Brake system fault codes related to the rear sensor circuit
• Driveability concerns caused by inconsistent ABS input

Installation Notes

Install SS20965 at the rear position only on the listed applications. Verify the connector shape, terminal count, and sensor routing before installation, and inspect the tone ring, hub area, and wiring path for damage or contamination. Because mounting hardware and wiring harness are not included, reuse or replace related components as needed during service.
