GDUKOP Reverse Parking Assist Sensors 4-Pack — Direct-Fit GM Compatible OE Replacement, Sealed Plug-and-Play

The GDUKOP 4Pcs Reverse Parking Assist Sensor is a direct-fit parking aid kit engineered to replace factory rear parking sensors on many GM vehicles and restore obstacle detection for safer reversing.

This four-piece sensor set is made as a compatible replacement for original equipment (OE) parking distance control (PDC) sensors used across a wide range of Cadillac, Chevrolet, GMC, Buick and Saturn models. If your factory sensor has failed, caused false beeps, or shows error codes, these sensors are manufactured to match the plug-and-play dimensions and electrical characteristics of the original parts, helping reinstate your vehicle's parking detection system.

How does this sensor perform in everyday parking situations?

These sensors are designed to detect obstacles behind the vehicle and report distance information back to the factory parking system. They help reduce blind spots by triggering audio/visual alerts through the vehicle’s existing interface, though effectiveness depends on correct installation and a functioning PDC control module.

• Provides accurate proximity sensing for low-speed reversing maneuvers.
• Sealed housing helps resist water and dust for reliable operation in rain or dust-prone conditions.
• Makes beeping/visual warnings consistent when integrated with compatible factory systems.
• Not a substitute for driver awareness—acts as an assistance tool only.

What does "direct-fit" and the listed OE replacement numbers mean for installation?

Direct-fit means the sensor matches the original sensor’s size, connector type and mounting orientation so it can be installed without modification in compatible vehicles. The included OE numbers indicate the factory references these sensors are intended to replace; matching those codes reduces the risk of buying the wrong unit.

• Plug-and-play style connectors are used on supported models for straightforward swaps.
• OE numbers provided let you cross-check against your vehicle’s part catalog or service manual.
• If your vehicle shows a P0504/PDC error, verifying connector and harness compatibility is recommended.

How should I inspect and maintain these sensors after installation?

Proper installation and occasional inspection help keep the sensors functioning reliably. Clean sensor faces and check the wiring harness after off-road or winter use to prevent moisture or dirt interference with readings.

• Wipe sensor faces periodically with a soft cloth to remove road grime and salts.
• Confirm seals and mounting clips are fully seated to preserve moisture resistance.
• Test operation in a safe area after installation to ensure correct alerts and behavior.

Who is this for: The GDUKOP 4Pcs Reverse Parking Assist Sensor kit is aimed at owners and technicians of compatible GM-family vehicles who need a reliable, cost-effective replacement for failing factory rear parking sensors. It’s suitable for DIY installers comfortable matching OE numbers and connector types, as well as professional shops servicing Cadillac, Chevrolet, GMC, Buick or Saturn models listed in the compatibility notes.
