Masoll TPMS Sensor Kit for GM Vehicles — 4-Pack Gen2 with EL-50448 Relearn Tool, Dual-Frequency

Masoll TPMS Sensor kit replaces factory tire-pressure sensors for GM vehicles and lets you clear TPMS warnings at home using the included EL-50448 relearn tool.

If your Chevy, GMC, Buick, or Cadillac shows a TPMS warning light, this Masoll set gives you a complete, do-it-yourself replacement solution. The package contains four programmable tire-pressure sensors and a GM-compatible TPMS relearn tool so you can install and sync sensors without a shop visit. Built as Masoll Generation 2, these sensors combine dual-frequency support, improved transmission range, and a robust housing aimed at trucks, SUVs, and passenger cars produced after 2006.

How will these sensors fit my GM vehicle?

Masoll Gen 2 TPMS sensors are designed to work across a broad range of GM-branded models and model years made after 2006. They are engineered to match OEM signaling expectations and include both 315MHz and 433MHz capabilities so you avoid frequency compatibility guesswork.

• Broad GM coverage: Chevy, GMC, Buick, Cadillac and select Pontiac models.
• Dual-frequency 2-in-1 sensor eliminates frequency mismatch.
• Recommended as direct replacements for factory internal sensors.
• Check vehicle list in product details for exact model-year fitment.

What does the DIY installation and relearn process involve?

Installation is straightforward: screw each sensor onto the valve stem, then use the included EL-50448 TPMS tool to teach the vehicle’s ECU the new sensor IDs. The process typically takes under five minutes per wheel for someone comfortable with basic tire work.

• Screw-on sensors—no valve removal or tire dismount required in most cases.
• EL-50448 tool programs sensor IDs to the car’s ECU for each wheel position.
• Stepwise relearn sequence documented in the product instructions.
• Swap and test each wheel to verify the system recognizes all sensors.

How accurate and long-lasting are these TPMS sensors?

Masoll sensors use a low-power design and include replaceable batteries rated for roughly two years in typical driving conditions. They report pressure with about 1.5 PSI precision, offering dependable readings for routine tire monitoring without frequent maintenance.

• Low power consumption for longer battery life, battery replaceable.
• Approximately 1.5 PSI measurement accuracy.
• Robust Gen 2 housing improves signal strength and durability.
• Each unit tested before shipping for consistent performance.

Who is this for? Drivers of GM vehicles—especially owners of pickup trucks like the Chevy Silverado and GMC Sierra, SUVs, and sedans—who prefer a cost-effective, at-home repair rather than a dealer visit. It’s also a good match for DIY mechanics and fleet managers who need a reliable, broad-coverage TPMS replacement that supports both 315MHz and 433MHz frequencies. If you want to replace factory sensors, stop a persistent TPMS warning light, and retain accurate pressure reporting without specialized shop labor, this Masoll kit provides the components and tool to get the job done.
