Marsflex TPMS Sensor for Toyota Tundra Sienna Sequoia 2007–2020 — Pre-programmed OE-style Replacement

Marsflex TPMS Sensor is a direct-fit replacement sensor engineered to restore accurate tire-pressure monitoring on compatible Toyota Tundra, Sienna, and Sequoia models from 2007 through 2020.

If your vehicle is showing a tire-pressure warning light or you want to replace ageing sensors before failure, this Marsflex unit offers a cost-effective, OE-style alternative. These sensors arrive pre-programmed for Toyota applications and are built to the same functional standards as original equipment, including long-life batteries and factory-style housing. Before installation, confirm vehicle compatibility using the seller's fitment checker, and plan to complete a TPMS relearn with an OBD-II relearn tool after mounting.

Will this sensor fit my Toyota model and year?

The Marsflex sensor is made to match the fit and function of many Toyota Tundra, Sienna, and Sequoia vehicles across multiple production years. Compatibility covers specific year ranges for each model; always verify with the vehicle fitment tool provided by the retailer prior to purchase. If the OE part numbers on your original sensor match the replacements listed below, these units should be appropriate.

• Compatible models and years: Toyota Sequoia (2008–2017), Sienna (2007–2020), Tundra (2007–2017)
• Replaces common OE numbers: 42607-0C070, 42607-08010, 42607-0C030, 42607-0C050, 42607-0C060
• Always cross-check with 'Amazon Confirmed Fit' or your vehicle's parts guide before ordering

How do I install and program this Marsflex TPMS sensor?

Installation requires removing the wheel and mounting the sensor to the valve stem inside the tire; it uses the same physical mounting method as OEM sensors. These Marsflex sensors come pre-programmed for Toyota, but a relearn procedure is still necessary so the vehicle's ECU recognizes each sensor's ID. The relearn is typically completed with an OBD-II TPMS tool or a dealer-level scanner supporting TPMS functions.

• Install sensor during tire mounting to avoid seal damage
• Use an OBD-II TPMS relearn tool to register sensor IDs with the vehicle
• Verify no air leaks and confirm the TPMS light clears after relearn

What can I expect in terms of durability and performance?

Marsflex sensors are manufactured new (not remanufactured) with batteries designed to provide multiple years of service under normal driving conditions. Production quality follows OE-like processes to ensure durability against vibration, temperature changes, and exposure to tire sealants. Each sensor is tested during manufacturing to confirm functionality before it ships.

• Brand-new sensor with factory-tested electronics
• Battery life designed to last several years in typical use
• Constructed to resist road and weather-related wear
