Delphi SS21440 Rear Left ABS Sensor
Delphi SS21440 is a rear left ABS wheel speed sensor built for accurate wheel-speed signal reporting in supported Ford and Mercury applications. It is a direct-fit replacement for 2009-2012 Ford Escape and 2009-2011 Mercury Mariner rear left positions, with OE-standard testing and calibration to help maintain consistent braking system performance.
- ABS wheel speed sensor for the rear left position
- Fits 2009-2012 Ford Escape, rear left
- Fits 2009-2011 Mercury Mariner, rear left
- Female connector with 1 connector, 2 terminals
- Blade terminal type with polygon connector shape
- Wiring harness included
- Package contents: ABS wheel speed sensor and instruction sheet
- Delphi part number SS21440
OE-Style Sensor Construction
Delphi sensors are developed and validated using OE-focused methods, with calibration and testing performed to OE standards for accurate readings. For Ford Escape and Mercury Mariner rear left ABS service, SS21440 provides the signal input the vehicle’s ABS system uses to monitor wheel speed and support proper brake control logic. This part cross-references Standard Ignition ALS2393 for the same application.
Common Issues This Part Can Address
- ABS warning light related to rear wheel speed signal loss
- Erratic or inconsistent wheel speed sensor readings
- Fault codes tied to the rear left ABS sensor circuit
- Brake system performance concerns caused by a failed sensor signal
- Intermittent ABS operation on the affected rear wheel
Installation Notes
Verify the rear left location before installation and compare the connector, terminal count, and harness routing to the original sensor. The sensor uses a female connector with blade terminals and includes a wiring harness; mounting hardware is not included. Confirm fitment by year, make, model, and position before replacing the original unit.
Quality Assurance
Delphi backs this ABS wheel speed sensor with OE development and product validation practices, and each sensor is tested and calibrated to OE standards to support accurate signal output and reduce repeat repairs.
