Yikesai Backup & Reverse Sensor Kit for Ford F-150 F-250 F-350 – 4X Rear Parking Sensors, OEM-Fit Weather-Resistant

Yikesai 4X Backup & Reverse Sensor Kit is a direct-fit OEM replacement set of four rear parking sensors designed to restore factory parking assist on compatible Ford, Lincoln and Mercury models.

If a damaged or failing sensor has turned your vehicle's parking assist into a guessing game, this Yikesai kit returns full rear detection capability with plug-and-play convenience. The set replaces part numbers like 684-029 and 3F2Z-15K859-BA and fits many Ford F-Series, E-Series vans, Explorers, Lincolns and select Mercury models produced in the 2000s and 2010s. Built for weather resistance and tested to meet OEM fit and function, these sensors are intended as a straightforward DIY fix that avoids costly service visits.

Which vehicles will accept these Yikesai backup sensors?

The kit was engineered to match factory specifications for a broad range of Ford, Lincoln and Mercury vehicles. Compatibility includes F-150, F-250, F-350 Super Duty ranges, E-Series vans, Explorer family models, and several Lincoln and Mercury platforms from the early 2000s through mid/late 2010s. Always verify the original part number or sensor location on your vehicle before ordering.

• Replaces part numbers: 684-029, 3F2Z-15K859-BA, 4F23-15K859-AA, T36006.
• Compatible models: Ford F-150/F-250/F-350, E-150/E-250/E-350, Escape, Explorer, Expedition, Freestar, Windstar.
• Also fits: Lincoln Mark LT, Mercury Mariner, Mountaineer.
• Check year ranges: select years 2002–2018 depending on model.

How easy is installation and what tools are needed?

Yikesai sensors are made for plug-and-play replacement, so most installations require only basic hand tools and minimal vehicle modification. The sensors mate to existing wiring harnesses and mount to the factory sensor locations, letting an experienced DIYer complete the job quickly. No special programming is typically required when replacing like-for-like OEM sensors.

• Standard tools: socket set, trim panel tools, screwdriver.
• Typical time: 20–60 minutes depending on access and experience.
• No cutting or splicing for true plug-and-play swaps.
• Replace faulty sensor(s) individually or install the full four-piece kit.

What performance and durability can I expect from these replacement sensors?

The sensors are built from weather-resistant materials and tested to withstand water, dust and temperature extremes typical of road use. Their sensing elements provide reliable proximity alerts to assist with parking maneuvers, helping you avoid low-speed impacts, scrapes and costly bodywork. While no sensor can prevent every incident, these units are designed to match the original equipment's detection and durability.

• Weatherproof construction resists moisture and debris.
• OEM-grade fit and finish for proper mounting and alignment.
• Engineered to restore complete rear detection when replacing failed units.
• Manufactured to hold up in typical driving environments.

Will replacing one sensor fix a system fault or do I need the full kit?

In many cases replacing a single failed sensor resolves a system fault; however, if multiple sensors are degraded or damaged, installing the full four-piece set guarantees balanced detection across the rear bumper. Use the kit to restore consistent sensor spacing and system reliability when several sensors are affected or when you prefer a complete like-new repair.

• Single-sensor replacement can clear localized faults.
• Full kit recommended when multiple sensors show wear or damage.
• Replacing all sensors avoids uneven sensitivity and blind spots.
• Verify fault codes and wiring before replacing sensors.

Who is this for: The Yikesai 4X Backup & Reverse Sensor Kit is ideal for owners of compatible Ford, Lincoln or Mercury vehicles who want a factory-fit parking assist repair without dealer markup. It's aimed at DIY enthusiasts, fleet managers, and anyone restoring a vehicle's rear detection system—especially when part numbers match the originals and plug-and-play replacement is preferred.
