Denso TPMS Sensor 550-0103 — Direct-Fit Replacement, Pre-Programmed OE Performance

The Denso 550-0103 is a direct-fit replacement TPMS sensor pre-programmed to match OE performance for select Lexus, Pontiac, Scion, and Toyota vehicles.

If your vehicle displays a tire pressure warning or a faulty sensor code, the Denso 550-0103 provides an OE-style replacement built to restore the original TPMS functions. Engineered by Denso in Japan, this sensor is designed to match the electrical and signal specifications used by the factory system so warnings, auto-locate, and fill-assist behaviors remain consistent with the vehicle’s design.

Which vehicles does this Denso TPMS sensor fit?

This sensor covers a wide range of Lexus, Pontiac, Scion, and Toyota models from the mid-2000s through the mid-2010s. Compatibility includes sedans, SUVs, trucks, and hybrids—refer to your vehicle’s model year and trim to confirm fitment. Using the correct, pre-programmed sensor helps avoid false warnings or partial system function.

• Lexus examples: CT200h, ES350, GS series, RX series, LX, GX, IS, LS, LFA, SC430 (various years listed by model)
• Pontiac: Vibe (2008–2010)
• Scion examples: iQ, tC, xB, xD (various years)
• Toyota examples: 4Runner, Camry, Corolla, Prius (incl. Plug‑In), Tacoma, Tundra, RAV4, Highlander, Land Cruiser, Sequoia, Matrix, FJ Cruiser, Venza

How is the 550-0103 different from generic TPMS sensors?

Denso sensors are built to OE tolerances and shipped pre-programmed for specific applications, so they behave like the factory unit without additional cloning in most cases. That reduces installation variables and helps maintain original system features such as auto-locate and fill-assist. Unlike some universal sensors, this part is matched to signal frequency and ID formats used by the listed vehicles.

• Pre-programmed to fit select makes/models—no universal reprogramming required for many vehicles
• Designed to preserve OE system warnings and locate functions
• Manufactured to Denso quality and battery-life expectations
• Made in Japan for consistent production standards

Will I need special tools or shop service to install this sensor?

Installation is a quick direct-fit job for a trained technician or experienced DIYer, but the vehicle’s TPMS relearn procedure is often required to reset the dashboard indicator. Denso sensors arrive ready for installation, yet some vehicles need a factory-specific relearn or scan-tool reset that is best handled by a trusted repair shop. Replacing valve hardware and service components each time a tire is removed helps ensure a reliable seal and long-term operation.

• Direct-fit replacement—sensor is pre-set to OE parameters
• Relearn or reset of TPMS may be required by vehicle manufacturer
• Replace valve cores and seals when servicing the tire for best results
• Professional shop recommended for those unfamiliar with TPMS relearn steps

What performance and service expectations should I have?

The Denso 550-0103 is engineered to meet the original equipment’s communication and battery life expectations so the TPMS system behaves as it did from the factory. Using Denso First Time Fit service components each tire removal helps restore the wheel assembly to original condition. While the sensor is pre-programmed, final system confirmation through a relearn clears codes and verifies the system recognizes the new sensor IDs.

• OE-level signal and battery life for dependable warning performance
• Use First Time Fit components for valves and seals during service
• Relearn step verifies dashboard indicator and system recognition
• 80% coverage across domestic and import applications

Who is this for: The Denso 550-0103 is for owners or technicians who need a factory-style TPMS replacement for compatible Lexus, Pontiac, Scion, and Toyota vehicles. It’s appropriate for drivers who want a pre-programmed, OE-quality sensor that preserves original TPMS functions, and for repair shops seeking a direct-fit part that minimizes troubleshooting and maintains system integrity.
