MANATEE Parking Sensors 4PCS Black — Front/Rear Direct-Fit Replacement for GM Vehicles

These MANATEE 4-piece front and rear PDC parking sensors (part nos. including 23428268, 84153946) replace factory ultrasonic radar sensors to restore parking-beep functions on compatible Chevy, GMC, Cadillac and Buick models.

If your vehicle’s parking sensors have stopped working or you need a direct-fit replacement without advanced steer-assist, this MANATEE kit provides four black sensors engineered to match OE mounting dimensions and electrical characteristics. Manufactured from durable materials and precision-tested, the set is intended for front or rear bumper locations on a range of GM vehicles listed in the fitment notes. It’s a sound-alarm type parking aid—suitable where Park Assist with Auto Steering (code UFQ) is not required.

Which vehicles and part numbers does this parking sensor set work with?

The MANATEE 4PCS kit is compatible with many GM models from roughly 2014–2021. It covers both front and rear bumper positions on specific Chevrolet, GMC, Cadillac and Buick vehicles when used as a traditional audible parking aid.

• Compatible lines include Chevy Camaro, Malibu, Impala, Silverado, Tahoe, Sonic, Trax, Suburban;
• GMC Sierra 1500/2500/3500 HD and Yukon XL models;
• Cadillac CTS, CT6, XT5, XTS and Escalade (check year fitment);
• Buick Encore and Lacrosse models (verify fitment by vehicle and sensor location).
• Part numbers referenced: 23428268, 26678454, 39088465, 42475184, 42475185, 52050134, 84078131, 84153946.

How do I install these sensors and what should I test first?

Installation typically involves removing the bumper cover, unplugging the original sensor, and plugging in the MANATEE replacement. Because wiring and connectors must match, it’s recommended to bench-test each sensor’s circuit before final reassembly to confirm audible response and continuity.

• Test wiring and connector pins for continuity and signal before mounting;
• Ensure sensor orientation and depth match the original to avoid false readings;
• Use a compatible mounting hole and secure the sensor until it snaps into place;
• After installation, verify parking beeps at low speed and adjust if needed.

What performance and quality features should I expect from MANATEE sensors?

These sensors are built from radar-grade materials with precision manufacturing to deliver reliable acoustic parking feedback. They are sold as brand-new units designed to be direct-fit replacements rather than refurbished cores.

• High-precision molding and tested housings for weather resistance;
• Factory-matching electrical characteristics for plug-and-play replacement in supported vehicles;
• Supplied in black to match many bumper trims and preserve vehicle appearance;
• Offered as a standard sound-alarm sensor, not a steer-assist module.

Will these work with vehicles that have automatic parking steer assist?

No—this MANATEE kit is a traditional audible parking sensor only. If your vehicle is equipped with Park Assist that requires automatic steering (factory code UFQ), this product is not compatible and will not provide the steering control functions.

• Compatible with systems that use beeping proximity alerts;
• Not compatible with modules requiring lane/steer integration or UFQ-equipped vehicles;
• Always verify your vehicle’s factory options and wiring before buying;
• Consult dealer or service manual when in doubt about system type.

Who is this for: This MANATEE 4-piece parking sensor set is intended for owners or technicians replacing failed front or rear proximity sensors on supported GM vehicles who need an OE-fit, acoustic parking aid replacement. It’s ideal for vehicles that lost sensor function, for body shops restoring parking systems after repairs, or for DIYers comfortable testing wiring and swapping bumper-mounted sensors. Confirm your vehicle’s year, model, and whether Park Assist with Auto Steering (UFQ) is present before purchase to ensure compatibility.
