Marsflex TPMS Sensors 42607-33021 for Toyota/Lexus — Preprogrammed OE‑fit, Long‑life Battery

These Marsflex sensors are built as brand-new replacements that mirror original-equipment functionality, offering long-life batteries and factory-style reliability. They arrive pre-programmed for targeted vehicle groups to minimize installation steps; a TPMS scan or relearn procedure is still required to sync sensors with your vehicle’s monitoring system. Marsflex backs the sensors with testing and a 1-year warranty for added confidence.

Which vehicles will these Marsflex TPMS sensors fit?

These sensors are programmed and dimensioned to match a wide range of Toyota and Lexus models plus some Scion and Pontiac vehicles. Instead of listing every model year here, verify fitment using the vehicle compatibility tool where available and check the OE cross-reference numbers.

• Common Toyota fits: Prius (incl. Prius V), Camry, Corolla, RAV4, Highlander, Tacoma, Tundra, 4Runner, Sequoia, Land Cruiser and more across mid-2000s to mid-2010s model years.
• Lexus coverage: CT, ES, GS, GX, HS, IS, LFA, LS, LX, RX and SC series within specified model years.
• Also compatible with Scion models (iQ, tC, xB, xD) and Pontiac Vibe in applicable years.
• Confirm by matching OE numbers (examples include 42607-33021 and related PMV-107J series).

How are the sensors supplied and what setup is required?

Marsflex ships these TPMS units pre-programmed to reduce the amount of initial configuration, but vehicles typically require a final relearn or registration step. Technicians commonly use a TPMS scan tool or the vehicle’s relearn procedure to register each sensor to the car’s ECU.

• Delivered pre-programmed for targeted applications to save programming time.
• Final TPMS relearn or scan-tool registration is recommended for correct dashboard readings.
• Follow vehicle-specific relearn steps or have a shop complete the registration if unsure.

What durability and performance features do Marsflex sensors include?

These sensors are manufactured as new units (not refurbished) and use batteries designed for long service life under normal driving conditions. Production follows OE processes aimed at match-fit reliability and consistent pressure and temperature reporting.

• 100% brand-new sensor housings and electronics, not remanufactured parts.
• Battery life engineered up to about eight years under typical use.
• Manufacturing tests performed to ensure signal stability and component durability.
• 1-year limited warranty covering defects and manufacturing issues.

Do these sensors replace original OE part numbers?

Yes — Marsflex units are produced to replace several factory OE part numbers commonly used across Toyota and Lexus fleets. Cross-referencing the part numbers helps ensure you select the correct sensor for your vehicle.

• Compatible replacement references include PMV-107J and multiple OE numbers such as 42607-33021 and related variants.
• Double-check your vehicle’s current TPMS part number or consult the fitment tool before purchase.
• If in doubt, capture the VIN and confirm compatibility with Marsflex or a trusted installer.

Who is this for: These Marsflex TPMS sensors are aimed at owners and mechanics replacing faulty or end-of-life tire pressure sensors on mid-2000s to mid-2010s Toyota and Lexus vehicles, and compatible Scion/Pontiac models. They are a practical option for anyone seeking new, pre-programmed replacements that match OE specifications, offer long battery life, and come with a one-year warranty. If you prefer a plug-and-play outcome, have a TPMS scan tool or professional installer available to complete the relearn step.
