Marsflex TPMS Sensor for Dodge Jeep Ram Chrysler — Pre-programmed Fit, Long-Life Battery

Marsflex TPMS Sensor is a direct-fit tire pressure monitoring sensor engineered to replace specific OEM units on select Dodge, Jeep, Ram, Chrysler and Fiat vehicles while delivering long battery life and factory-style reliability.

This Marsflex replacement sensor is pre-programmed to match the signal and frequency of compatible vehicles listed below, offering a cost-effective way to restore your vehicle's tire-pressure monitoring without buying an OEM part. Although the sensor ships pre-programmed, it must be relearned to the vehicle with a diagnostic scanner or activation tool so your car recognizes each sensor after installation.

Which vehicles will this Marsflex TPMS sensor fit?

The sensor is made for a wide range of Chrysler-Fiat family models and several Ram trucks produced in the years specified. Use the Amazon Confirmed Fit tool before purchasing to double-check fitment for your exact year and trim.

• Chrysler/Dodge/Jeep/RAM/Fiat model groups: Challenger, Charger, Durango, Grand Caravan, Journey, C/V, Town & Country, 300
• Jeep models: Wrangler (2013–2021), Grand Cherokee (2011–2015), Gladiator (2020–2021)

How does this sensor compare to the original OEM unit?

Marsflex sensors replace specific OE part numbers and are built to meet or closely match original specifications for mounting, signal frequency, and battery life. They are brand new units with replacement batteries designed to last up to eight years under typical use.

• Direct OE numbers replaced: 5154876AB, 56029398AA/AB, 68241067AA/AB, 68142397AA, 68406537AA
• Factory-style fit and mounting to match original sensor dimensions
• Pre-programmed at the factory to simplify pairing, though a relearn is required

Will I need special tools to install and activate the Marsflex TPMS sensor?

Physical installation uses the same procedures as OEM sensors, but electrical pairing requires a TPMS relearn process. You will need a professional diagnostic scanner or a TPMS activation tool to complete the relearn so the vehicle’s ECU recognizes the new sensor IDs.

• Install with normal tire removal and valve-stem procedures
• Use a TPMS activation tool or dealership diagnostic scanner for relearn
• If unsure, have a tire shop or mechanic perform the final relearn and sensor test

What performance and warranty details should I expect?

Marsflex sensors are tested during manufacture for durability and signal consistency. The battery is rated for approximately eight years of typical use, and Marsflex provides one year of after-sales support should you encounter defects or questions.

• 100% brand-new sensor units with warranty-backed support
• Battery life designed to mirror OEM longevity under normal driving conditions
• One-year after-sales service and manufacturer testing for quality control

Who is this for: This Marsflex TPMS sensor is intended for owners of compatible Dodge, Jeep, Ram, Chrysler and Fiat vehicles who need an economical, OEM-compatible replacement for a failed or lost tire-pressure sensor. It’s suitable for DIY installers comfortable with tire work and for shops that can perform the required TPMS relearn. Before ordering, confirm compatibility with the Amazon Confirmed Fit tool and plan for a relearn step with a professional tool if you don’t have one at home.
