Delphi SS20843 ABS Wheel Speed Sensor - Rear Right

Delphi Rear Right ABS Wheel Speed Sensor

The Delphi SS20843 ABS wheel speed sensor is built for rear right applications on select Lexus and Toyota vehicles. It delivers OE-standard calibration and validated sensor output to support accurate wheel speed readings for ABS system operation.

Compatible with 2014-2018 Toyota RAV4, 2015-2017 Lexus NX200t, 2015-2021 Lexus NX300h, and 2018-2021 Lexus NX300, this rear right sensor is a direct-fit service part for common ABS warning light concerns. The Delphi SS20843 is also a practical replacement when the original sensor signal becomes inconsistent or fails.

• Rear right ABS wheel speed sensor for select Lexus and Toyota applications
• OE-standard testing and calibration for accurate wheel speed signal output
• Female connector with 2 terminals and rectangular connector shape
• Blade terminal type with included wiring harness
• Package contents include the ABS wheel speed sensor and instruction sheet
• Length: 38.19; wiring harness length: 3.54

Detailed Description

Delphi SS20843 is engineered as an ABS wheel speed sensor for the rear right position. Delphi validates its sensors to OE standards, helping ensure the module receives the correct wheel speed data needed for stable ABS performance. This part cross-references Standard Ignition ALS2575 for the same application.

Use this sensor on 2014-2018 Toyota RAV4, 2015-2017 Lexus NX200t, 2015-2021 Lexus NX300h, and 2018-2021 Lexus NX300 when the original rear right sensor is damaged, contaminated, or no longer reporting correctly. The Delphi SS20843 is a focused replacement for vehicles that rely on precise wheel speed input for braking system control.

What It Helps Address

• ABS warning light triggered by a failed rear wheel speed sensor
• Erratic or missing wheel speed signal at the rear right corner
• Brake system fault codes related to wheel speed input
• Loss of ABS function caused by sensor wear or connector damage
• Drivability concerns tied to inaccurate wheel speed data

Installation Notes and Tips

Confirm rear right placement before installation and compare the connector, terminal count, and harness routing to the original part. Inspect the tone ring, hub area, and wiring path for damage or contamination before fitting the new sensor. Verify the sensor seats fully and the harness is secured away from moving suspension components.

Quality Assurance

Delphi backs this sensor with OE development and product validation methods, and each unit is tested and calibrated to OE standards for consistent readings. That level of validation supports reliable replacement performance on Lexus NX300, Lexus NX300h, Lexus NX200t, and Toyota RAV4 applications.
