Marsflex TPMS Tire Pressure Sensor for Dodge Jeep RAM Chrysler — Pre-Programmed Direct-Fit Replaces OE Numbers

Marsflex TPMS Sensor is a direct-fit, pre-programmed tire pressure monitoring sensor designed to replace factory units on many Dodge, Jeep, RAM and Chrysler vehicles.

This sensor is built to match factory specifications and comes pre-programmed for straightforward installation on compatible models. It replaces several OE part numbers and uses the same mechanical design and battery technology as original equipment to deliver long-lasting monitoring of tire pressure. Although it arrives programmed, a relearn or activation step with a diagnostic tool is required to pair the sensor with your vehicle’s TPMS system.

Which vehicles will this Marsflex sensor fit?

The Marsflex TPMS Sensor covers a wide range of Chrysler Group vehicles across model years commonly found on the road. It fits many Dodge, Jeep, RAM, Chrysler and Fiat applications — from passenger cars to light trucks and vans — but always confirm fitment before ordering.

• Common Dodge fits: Challenger, Charger, Durango (2010–2022 ranges vary by model year)
• Jeep fits: Wrangler, Gladiator, Grand Cherokee across several model years
• RAM and Chrysler: 1500/2500/3500 series, Town & Country, 300 and others as listed
• Also compatible with Fiat 500 variants and select commercial/van platforms

What OE numbers does it replace and why verify fitment?

Marsflex sensors are engineered to replace specific original equipment part numbers, ensuring correct mechanical fit and signal output. Confirming vehicle compatibility helps avoid ordering the wrong sensor; use an online confirmed-fit tool or VIN lookup for accuracy.

• Replaces OE: 5154876AB, 56029398AA/AB, 68241067AA/AB, 68142397AA, 68406537AA
• Use Amazon Confirmed Fit or VIN search to verify your exact model year and axle application
• Matching OE numbers reduces the chance of incompatibility with your vehicle’s receiver

Is the sensor ready to use right out of the box?

The sensor ships pre-programmed to a known specification but is not automatically paired with your vehicle. After installation you must perform a relearn or activation procedure with an approved diagnostic scanner or TPMS tool to register each sensor to the vehicle’s system.

• Pre-programmed for time savings during installation
• Relearn needed: professional diagnostic tool or activation device required
• Follow vehicle-specific relearn steps — often available in service manuals or through repair shops

How durable is the Marsflex TPMS Sensor and what support comes with it?

These sensors are manufactured to meet industry standards for reliability, with battery life engineered for extended use. Marsflex offers a one-year after-sales service window, and each unit undergoes testing during production to ensure consistent performance.

• Brand-new sensor with production testing for quality control
• Battery lifespan designed up to 8 years under normal conditions
• One-year after-sales support for product questions and warranty assistance

Who is this for? The Marsflex TPMS Sensor is intended for vehicle owners, fleet managers, and service technicians seeking a cost-effective, factory-style replacement for faulty or expired tire pressure sensors on compatible Dodge, Jeep, RAM, Chrysler and Fiat models. It’s a practical choice when you want OE-equivalent fit and proven battery longevity, provided you or your installer can complete the required TPMS relearn using proper diagnostic equipment.
