Marsflex Tire Pressure Sensor for Ram 1500 (2019–2025) — Replaces OE 68293199AA, 433MHz Pre‑programmed TPMS

Marsflex Tire Pressure Sensor is a direct-fit TPMS replacement for Ram 1500 models (2019–2025) designed to match OE 68293199AA performance and operate on 433MHz.

If your Ram 1500 displays TPMS warnings after a sensor failure or after replacing tires, this Marsflex sensor is built to deliver a factory-style fit and longevity. It comes pre-programmed to the correct part profile but requires a vehicle relearn procedure with a diagnostic tool or activation device to complete pairing. The battery is rated for up to eight years under normal driving conditions and the unit is tested during production to meet durability expectations.

How will this sensor fit my Ram 1500?

The Marsflex TPMS is engineered to be compatible with Ram 1500 model years 2019 through 2025, including Ram 1500 DT 2019–2024. It is manufactured to replace OE part number 68293199AA and transmits on the 433MHz band commonly used by these vehicles. Always confirm vehicle compatibility by checking your OE number and using the retailer’s fitment tool before ordering.

• Compatible years: 2019, 2020, 2021, 2022, 2023, 2024, 2025.
• Also fits Ram 1500 DT series within listed years.
• Replaces OE 68293199AA and uses 433MHz frequency.
• Verify fit with VIN or seller’s confirmed-fit tool before purchase.

Does the sensor come ready to use right out of the box?

This Marsflex unit arrives pre-programmed to the correct sensor profile, but pre-programming does not equal automatic pairing with your truck. After installation you must perform a TPMS relearn or use an activation tool/diagnostic scanner so the vehicle recognizes each sensor’s ID. Many tire shops, dealerships, or DIYers with the right tool can perform the relearn quickly.

• Pre-programmed profile reduces setup time for technicians.
• Relearn required using a scanner or activation tool.
• Professional shops can complete pairing if you don’t have a tool.
• Follow vehicle-specific relearn steps for reliable operation.

What kind of durability and performance can I expect?

Marsflex sensors are new, not refurbished, and include a long-life battery rated up to eight years under normal use. Units are produced using processes similar to OE parts and undergo factory testing to ensure signal reliability and resistance to road conditions. While durable, normal wear, impact, or corrosion can shorten lifespan—inspect sensors during tire service.

• 100% brand-new sensors with long-life battery (up to 8 years).
• Manufactured and tested for reliability and durability.
• Designed to meet the same basic expectations as OE components.
• Inspect and maintain valves during tire changes to maximize life.

Who is this for: This Marsflex TPMS sensor is intended for Ram 1500 owners (2019–2025) who need a direct OE-equivalent replacement for failed or aging sensors, service shops performing TPMS repairs, and DIYers comfortable completing an installation and performing the required relearn with a diagnostic tool or visiting a technician to finalize pairing. Confirm your vehicle’s OE number and 433MHz requirement before ordering, and plan for a relearn step after physical installation to restore full TPMS function.
