Delphi SS20794 ABS Wheel Speed Sensor - Front

Delphi Front ABS Wheel Speed Sensor SS20794

Delphi SS20794 is a front ABS wheel speed sensor built for accurate wheel-speed signal input and OE-style fitment. It is a direct replacement for select Audi applications, including Audi A4, A5, A6, Q5, Q7, Q8, S4, S5, S6, S7, S8, SQ5, SQ7, SQ8, RS models, and e-tron variants.

Delphi validates and calibrates its sensors to OE standards, helping deliver consistent readings for the ABS system. If you are replacing a front Audi ABS wheel speed sensor, SS20794 is engineered for the same application as the original part.

Key Features

• Front ABS wheel speed sensor for select Audi vehicles
• Part number SS20794 for easy identification
• Blade terminal type with 2 terminals
• Oval connector, male connector gender, 1 connector
• No mounting hardware included
• No wiring harness included
• Package contents: ABS wheel speed sensor and instruction sheet
• OE-standard testing and calibration for accurate signal output

Detailed Description

Delphi SS20794 is an ABS wheel speed sensor designed for the front position on a wide range of Audi platforms. It supports vehicles such as the 2016-2022 Audi A4 Quattro front, 2018-2022 Audi Q5 front, 2017-2022 Audi Q7 front, 2019-2022 Audi Q8 front, and 2021-2023 Audi RS5 front. This part number also covers additional front-fit Audi applications including A6 Quattro, A7 Sportback, S4, S5, SQ5, e-tron Quattro, and related models.

Delphi’s sensor portfolio is developed with OE-focused validation methods, and each sensor is tested and calibrated to OE standards to help maintain accurate wheel-speed data for the ABS system. This part cross-references Standard Ignition ALS3236 for the same application.

What It Helps Address

• ABS warning light caused by a failed front wheel speed sensor
• Erratic or missing wheel-speed signal input
• Traction control or stability system faults tied to wheel-speed data
• Intermittent ABS operation from sensor signal loss
• Brake system fault codes related to the front sensor circuit

Installation Notes and Tips

Verify the connector shape, terminal count, and front position before installation. Compare the removed sensor to SS20794 to confirm the oval connector and blade-style terminals match your vehicle. Inspect the tone ring, hub area, and wiring path for damage or contamination before installing the new sensor. Clear fault codes and road test the vehicle after installation to confirm proper ABS operation.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and the sensor is tested and calibrated to OE standards for accurate readings. That level of validation helps support reliable front wheel-speed signal performance on Audi A4, A5, A6, Q5, Q7, Q8, S4, S5, SQ5, RS5, and e-tron applications.
