Marsflex TPMS Sensors 315MHz 4-Pack — Pre-Programmed OE-Fit Replacement with 8-Year Battery

Marsflex 42607-33021 TPMS sensors are a set of four replacement 315MHz tire pressure monitoring sensors pre-programmed for many Toyota, Lexus, Scion and Pontiac models but require a relearn procedure after installation.

If you need a reliable aftermarket TPMS replacement that matches OE fit and frequency, these Marsflex sensors offer direct fitment for numerous Toyota and Lexus vehicles plus select Scion and Pontiac models. Each sensor arrives new with an internal battery rated for up to eight years of typical use and is manufactured to mirror OE quality and durability. They come pre-programmed to common OE IDs, but pairing with your vehicle’s computer still needs a professional relearn or activation tool.

Which vehicles will these Marsflex TPMS sensors fit?

These sensors are intended for many Toyota models from the mid-2000s through the mid-2010s, plus a broad range of Lexus series and several Scion models. Use the vehicle fit checker (Amazon Confirmed Fit) before purchase to ensure exact compatibility, as model years vary by series.

• Toyota: Camry, RAV4, Highlander, Tacoma, Prius, 4Runner, Land Cruiser, and more (specific years listed by model).
• Lexus: ES, GS, IS, RX, LX, LS, CT, GX, SC and LFA series coverage for various years.
• Scion and Pontiac: select iQ, tC, xB, xD and Pontiac Vibe model years.

How do I install and activate these pre-programmed sensors?

Installation involves mounting each sensor to the wheel valve stem and tightening to the specified torque. Although pre-programmed, the sensor IDs must be registered to your vehicle’s TPMS system through a relearn process using a diagnostic scanner or activation tool; many tire shops and dealerships can perform this service.

• Mount sensors to each wheel valve stem and torque per manufacturer recommendations.
• Perform a TPMS relearn with an OBD or scan tool, or use a professional tire shop to activate sensors.
• Check dashboard TPMS light and use a scanner to verify each sensor’s signal and battery status.

What quality and lifespan can I expect from Marsflex TPMS sensors?

• 100% brand-new sensors, built to OE-style manufacturing standards.
• Internal battery rated up to 8 years of typical operation.
• Factory-tested for functionality before shipping; 1-year after-sales support is provided.

Can these Marsflex sensors replace specific OE part numbers?

• Replaces OE numbers like PMV-107J, 42607-06011, 42607-30030, 42607-33011 and 42607-33021.
