Schrader TPMS Solutions EZ-Sensor Programmable TPMS Sensor 4-Pack — Multi-Frequency 314.9/315/433 MHz, OEM-Quality

Schrader 33500 EZ-Sensor® Programmable TPMS Sensor 4 Pack is a programmable, OEM-quality tire-pressure monitoring sensor bundle designed to be programmed and installed by a trained technician to restore factory TPMS function.

The Schrader 33500 EZ-Sensor® merges multi-frequency compatibility into a single, serviceable sensor built to OEM quality standards. Supplied as a four-pack, these sensors simplify inventory by supporting 314.9, 315 and 433 MHz protocols when programmed correctly. They must be programmed with a compatible TPMS tool before wheel installation and vehicle relearn, ensuring reliable integration with the vehicle’s existing TPMS system and the same operational behavior as original equipment sensors.

How does the EZ-Sensor® replace my vehicle’s factory TPMS sensors?

When the 33500 is programmed to the vehicle year, make, and model using a compatible tool, it emulates OEM sensor behavior including auto-locate functionality. After programming and physical installation into the rim, follow the vehicle manufacturer’s TPMS relearn procedure to bind the sensors to the car’s system.

• Programs to vehicle-specific protocol before wheel installation.
• Performs identically to OE sensors once programmed.
• Supports auto-locate technology for easy integration.

What tools and skills are required to install Schrader 33500 sensors?

This sensor is not a DIY product; it requires a trained technician and a TPMS programming tool with up-to-date software. The tool must support the vehicle’s protocol and be capable of writing sensor IDs and frequency settings prior to installation.

• Compatible TPMS programming tool with latest software update.
• Technician experienced in programming and wheel service.
• Follow the three-step process: program, install, and relearn.

Will these sensors fit all vehicles and frequencies?

The 33500 EZ-Sensor® covers 314.9, 315 and 433 MHz applications when programmed, making it broadly compatible with many North American and international vehicles. However, always confirm tool and vehicle compatibility before purchase and programming.

• Multi-frequency design reduces the need for multiple SKUs.
• Check your TPMS tool’s vehicle coverage list for exact compatibility.
• Keep programming tool firmware current for new vehicle support.

What are the mechanical and performance limits of the sensor?

Schrader designs the 33500 to meet strict OEM-quality requirements and operating limits. The sensor is rated for typical passenger-car usage and includes torque and pressure specifications for safe installation and operation.

• Maximum speed rating: 130 MPH (approx.).
• Maximum pressure rating: 80 PSI.
• Recommended valve core torque: 3.5 in-lbs during installation.

Who is this for: The Schrader 33500 EZ-Sensor® 4 Pack is aimed at professional tire shops, service centers, and fleet technicians who need a versatile, OEM-quality TPMS sensor solution that reduces inventory complexity. It's ideal for technicians who use a compatible TPMS programming tool and follow manufacturer relearn procedures to return vehicles to factory TPMS functionality.

Quick step-by-step install summary:

• Program each sensor with a compatible TPMS programming tool to the vehicle’s protocol.
• Install the programmed sensors into the wheels and torque valve components per specs.
• Execute the vehicle factory TPMS relearn procedure to register the sensors.

Note: Maintain your TPMS scan and programming tool software updates to ensure the broadest vehicle coverage and avoid fitment issues. The Schrader EZ-Sensor® 33500 is engineered to match OE function without altering your vehicle’s intended TPMS performance.
