Schrader TPMS Solutions 33500 EZ-Sensor Programmable TPMS Sensor, Multi‑Frequency 314.9/315/433 MHz — Snap‑in Fixed‑Angle Valve

The EZ-Sensor 33500 from Schrader TPMS Solutions is a universal-style, fixed-angle valve tire pressure monitoring sensor designed to replace original equipment sensors across multiple frequencies. It reduces inventory needs by combining three common radio frequencies into a single sensor body, and it requires programming with the vehicle Year, Make, and Model using a supported TPMS tool prior to wheel installation and relearn procedures. Keep tool software updated to maximize vehicle coverage and reliable operation.

How does programming the EZ-Sensor work and why is it required?

Programming configures the sensor to match the vehicle’s TPMS protocol so the vehicle’s system recognizes it as a valid sensor. The process uses a compatible diagnostic/programming tool to select the correct Year, Make, and Model profile, write the sensor data, and then install the sensor into the wheel before performing the vehicle relearn.

• Requires a compatible TPMS tool (see compatible list).
• Program with vehicle Year, Make, and Model protocol before mounting.
• Install sensor into the rim after programming and then complete relearn.
• Keep tool firmware updated for widest vehicle coverage.

Which tools work with the Schrader 33500 EZ-Sensor?

The EZ-Sensor is supported by a wide range of Schrader and aftermarket TPMS tools. Popular options include Schrader’s own handhelds and several third-party manufacturers; confirm the tool has the latest software update for full compatibility with recent vehicle models.

• Schrader: ST-1, S-56, S-46, S-41, EZ-Sensor PAD.
• ATEQ: VT-57, VT-56, VT-36, VT-37, VT-67 series.
• Bartec: multiple TECH series and TechRITEPro models.
• Snap-On: TPMS5, TPMS4, TPMS3 supported.

What performance and quality features does the EZ-Sensor offer?

The 33500 is built to mirror OE sensor behavior, including auto-locate functionality and design specifications that match OEM standards. Once programmed, it functions like an original sensor and supports evolving vehicle system protocols, helping technicians deliver consistent TPMS service.

• Multi-frequency design reduces SKUs and streamlines inventory.
• OEM-quality construction and replicated OE functionality.
• Auto-locate technology for efficient vehicle relearns.
• Future-proofed for many new and pending OE TPMS protocols.

How should technicians prepare before installing a programmed EZ-Sensor?

Confirm that the programming tool is updated to the newest software release and that the correct vehicle protocol was written to the sensor. Program before installing into the wheel, then follow the vehicle manufacturer’s relearn procedure; this sequence helps ensure the vehicle recognizes the sensor on first attempt.

• Update TPMS tool firmware before programming.
• Verify vehicle Year/Make/Model profile selection during programming.
• Mount the sensor after programming, then run the relearn procedure.
• Use OBDII or TPMS relearn as required by the vehicle.

Who is this for: The Schrader 33500 EZ-Sensor is intended for professional technicians, independent repair shops, and fleets that need a reliable, multi-frequency replacement TPMS sensor. It’s ideal for operations that want to reduce part SKUs, offer fast TPMS repairs, and ensure compatibility across a broad range of vehicles—provided they use a compatible programming tool and maintain its software updates.
