Marsflex TPMS Sensor 13598773 433MHz 4PCS - Pre-Programmed Fitment

In this review the Marsflex TPMS Sensor 13598773 433MHz kit is evaluated for drivers who need direct-replacement tire pressure monitoring sensors for a range of Chevrolet, Buick, GMC and Cadillac models. The bottom line: this four-pack is best for owners and independent shops who want sensors that arrive pre-programmed to OEM specification and only require activation with a scan tool, saving time on programming while delivering the expected signal reliability for daily driving.

Key Features

• Pre-programmed: The sensors arrive pre-programmed so installers can skip manual programming and move straight to activation with a scan tool, reducing shop time.
• OEM fit: Manufactured to OEM specification to provide direct compatibility with many Chevrolet, Buick, GMC and Cadillac vehicles listed in the fitment guide.
• Long-life battery: Each sensor includes a CR2032B battery rated for an extended operating range and a multi-year service life, lowering the need for frequent replacements.
• Strong signal chip: The upgraded chip improves signal strength for reliable real-time tire pressure readings to keep the dash clear of warning lights when properly activated.
• Replace OE numbers: Intended as replacements for several OE numbers including 13598773 and 13516165, simplifying purchase for common sensor swaps.

Who It's For

The kit is aimed at owners of supported Chevrolet models such as Camaro, Cruze, Impala, Malibu, Silverado and Volt who want a cost-effective alternative to dealer sensors and prefer a pre-programmed option to save installation time. Independent mechanics and tire shops will also appreciate arriving pre-programmed units that only need activation with a scan tool.

Those who should look elsewhere are owners of vehicles not listed in the stated fitment ranges or buyers who require sensors with a different frequency or proprietary valve style. Also, buyers without access to an activation scan tool should plan on a shop visit to complete the setup.

Pros & Cons

Pros

• Pre-programmed out of the box saves time during installation and simplifies replacement.
• Built to OEM specification for fit and function across multiple GM nameplates in the listed years.
• Upgraded battery and chip offer extended operating temperature range and improved signal performance.

Cons

• Requires a scan tool for activation after installation, so DIYers without one may need professional help.
• Fitment must be confirmed against each vehicle model and year; not universal for all GM vehicles.
