Relearn Tire Sensors with Confidence
The EL-50448 TPMS Activation Tool (OEC-T5) helps compatible GM vehicles recognize tire pressure sensor positions after tire rotations, sensor replacement and wheel service. Designed for compatible 315 MHz and 433 MHz TPMS systems, with straightforward one-button sensor activation.
From $25.99
9V battery required and sold separately.
Free shipping on orders of $50 or more to all destinations we serve. Shipping options are confirmed at checkout.
Purpose-built to activate compatible TPMS sensors during a vehicle relearn procedure.
1. Make Tire Sensor Relearning Simpler
After rotating tires, replacing a compatible TPMS sensor or replacing a remote-control door-lock receiver module on a vehicle that requires it, the vehicle may need to relearn which sensor belongs at each wheel position. The EL-50448 helps trigger each sensor while the vehicle is in its TPMS learning mode, so the onboard system can register the positions.
2. Designed for Compatible GM Vehicles
Designed for many North American Chevrolet, Buick, Cadillac and GMC vehicles equipped with a compatible 315 MHz or 433 MHz tire pressure monitoring system. Some 2014 GM vehicles are among the compatible applications.
Before ordering: Check your vehicle's year, model, sensor frequency and TPMS relearn procedure. Compatibility is not universal; aftermarket sensors with a different frequency or system may not respond.
3. Dual-Frequency Support & One-Button Operation
With support for compatible 315 MHz and 433 MHz TPMS sensors, the EL-50448 offers a convenient handheld activation method. Enter your vehicle's relearn mode, position the tool close to the tire's valve stem and press its activation button.
This is a TPMS sensor activation and relearn aid. It does not directly display tire pressure in PSI, program blank sensors or replace a full diagnostic scan tool.
4. How to Use the EL-50448
A typical compatible GM sensor relearn follows the sequence below. The exact menu names and confirmation signals vary by vehicle, so follow your owner's manual or service instructions.
Park safely, shift to P and turn the ignition on without starting the engine, where applicable. Open the tire pressure relearn function using the vehicle's driver information display or specified controls. Some GM vehicles confirm with two horn chirps.
Hold the EL-50448 antenna close to the tire sidewall near the valve stem at the left-front wheel. Press the activation button. On many GM vehicles, one horn chirp confirms that the sensor has been learned.
Follow the typical order: left front, right front, right rear, then left rear. Activate each sensor only when the vehicle is ready for that position.
After the final wheel, some vehicles confirm completion with two horn chirps. Exit relearn mode and check tire pressures against the vehicle's recommended specification.
5. Choose Your Package
Pick the package that suits your needs using the product options above. Both options contain the same EL-50448 tool model, and neither includes a battery.
Battery reminder: A 9V battery is required for each tool and is not included. The Buy 2 package alone is below the $50 free-shipping threshold.

Frequently Asked Questions
What does the EL-50448 do?
It activates compatible GM tire pressure sensors during a TPMS relearn process, allowing the vehicle to register sensor positions after tire or sensor service.
Will it show tire pressure in PSI?
No. This is a sensor activation tool, not a tire pressure gauge or full diagnostic scanner. Check actual tire pressure with a suitable gauge or vehicle display.
Does it support 315 MHz and 433 MHz?
Yes, for compatible GM TPMS sensors using those frequencies. Match the vehicle and sensor system before ordering.
Does it work with every GM vehicle?
Not necessarily. Many Chevrolet, Buick, Cadillac and GMC models are supported, but fit depends on model year, sensor type, frequency and relearn procedure.
Can it program replacement TPMS sensors?
It can activate compatible sensors during relearn; it does not program blank sensors or write sensor IDs.
Is a battery included?
No. Each tool requires one 9V battery, which must be purchased separately.
What is the difference between Buy 1 and Buy 2?
Buy 1 contains one tool for $25.99. Buy 2 contains two tools for $35.99 total. Batteries are not included with either option.
How does free shipping work?
Orders of $50 or more qualify for free shipping to destinations we serve, including the United States and supported international destinations. Both packages individually cost less than $50; final shipping options appear at checkout.
