- Delphi part number SS21504
- OE-standard testing and calibration for accurate readings
- Wiring harness included for the sensor assembly
- Black connector with square shape, 1 connector, 2 terminals
- 500 mm wiring harness length
- Package contents: ABS wheel speed sensor and instruction sheet
Detailed Description
Delphi SS21504 is engineered for rear wheel-speed signal monitoring in 2020-2024 Tesla 3 and 2020-2024 Tesla Y vehicles. Delphi validates its sensor lineup to OE standards, helping maintain accurate wheel-speed data for ABS operation and reducing repeat repairs caused by incorrect signal output. This part cross-references Monroe Shocks & Struts (e.g., 1188771-00-A) for the same application.
What It Helps Solve
- ABS warning light triggered by a faulty rear wheel speed sensor
- Erratic or missing wheel-speed signal data
- Brake system fault codes related to rear sensor input
- Loss of anti-lock brake function caused by sensor failure
- Intermittent braking system alerts on Tesla 3 and Tesla Y models
Installation Notes and Tips
Verify rear-position fitment before installation on the vehicle. Inspect the connector, harness routing, and mounting points for damage or corrosion before connecting the new sensor. Confirm the square male connector and terminal layout match the original part, and clear any stored ABS fault codes after installation.
Quality Assurance
Delphi backs this sensor with OE-focused development and product validation methods. Each sensor is tested and calibrated to OE standards to support accurate readings and dependable brake-system input.
