Front, rear and body style
On the 2019-2023 Sierra 1500, the main split is front versus rear. GM lists one front sensor and a separate rear sensor for these trucks, and the front sensor is cataloged across 2WD and 4WD trucks and many trims and engines, from the 2.7L to the 6.2L. Cab and bed length do not normally change it.
The 2019 model year needs a check. The older body Sierra 1500 Limited was sold alongside the new truck, and they should not be assumed to share sensors. Confirm by VIN. Compare the connector, wire length and clip on your old sensor, and route the new lead the same way.
Why the sensor gets replaced
The wear sensor tells the truck when pad lining is getting thin. Once it touches the rotor and wears through, it has done its job and needs replacing with the pads. Sensors are also damaged during brake work, or fail from a corroded, loose or broken connector.
A brake wear warning does not always mean only the sensor is bad. Measure pad thickness, look at the rotors and check the wiring. Some trucks in this family have shown faster than expected front pad wear, so inspect both axles when the warning appears.
Pads, sensor and install
Replace the sensor whenever you replace worn pads that set off the warning. Check whether your new pads already come with a sensor, since some do and you will not need a second one. Most listings here are a single sensor, so order front and rear separately if both are worn.
With the truck on jack stands, remove the wheel and usually the caliper to reach the pad and sensor. Clip the new sensor into place and route the lead exactly like the original so it cannot touch the rotor or wheel. Seat the connector fully, then confirm the warning clears.

Sierra 1500 questions
Are front and rear Sierra 1500 brake pad sensors the same?
No. GM lists separate front and rear sensors for the 2019-2023 Sierra 1500. Pick the position that matches the axle you are servicing in each listing.
Do I need a new brake pad sensor every time I change pads on my Sierra?
Replace it if the sensor has worn through, is damaged, or your new pads do not include one. A worn sensor will keep the brake warning on even with new pads.
Does a 2019 Sierra 1500 Limited use the same brake pad sensor?
Do not assume so. The 2019 Limited is the older body, cataloged apart from the new 2019 Sierra 1500. Confirm with your VIN before ordering.
