Detailed Product Information

The SKP SK684019 is a body sensor replacement for rear parking aid systems on select Ford applications. It is engineered to communicate obstacle detection through the vehicle’s warning system, supporting accurate low-speed parking feedback. This part cross-references Standard Ignition PPS18 for the same application.

Compatible With 2001-2005 Ford Excursion rear and 2002 Ford Expedition rear applications, this sensor is a direct-fit service part for vehicles equipped with a rear parking aid system. The SK684019 part number is also a useful reference when verifying the correct replacement for your vehicle.

Common Issues This Part Can Address

  • Inoperative rear parking aid warning response
  • Faulty sensor readings from the rear bumper area
  • Intermittent audible or visual parking alerts
  • Damage from impact, moisture, or road debris
  • Parking assist system faults tied to a failed rear sensor

Installation Notes and Tips

Confirm the original sensor location and connector style before installation. Inspect the bumper opening, wiring, and related parking aid components for damage or corrosion, since a sensor replacement will not correct unrelated harness or module issues. Verify vehicle fitment by year, make, model, and rear position before ordering.

Quality Assurance

SKP manufactures this parking aid sensor to meet or exceed OE specifications for performance and durability. The SK684019 is built as a replacement part for factory-style rear parking assist systems.
