No programming required before installation - follow OE relearn procedure after installation.

Dorman's Tire Pressure Monitoring System (TPMS) Sensor features a unique two-piece design that allows for replacement of the valve stem independently of the sensor. The sensor also offers an adjustable angled stem, so an exact fit is ensured. Likewise, proper function is ensured: though the look and color of the sensor may vary from the factory-installed one, the internal electronics are customized for your specific vehicle, and will provide the same service as the original.

Features & Benefits:
  • Replaceable aluminum valve stem is anodized for long-lasting corrosion resistance-and may be serviced separately from the entire unit
  • Comes with stem unit, grommet, washer, and hex nut for a complete installation
  • Sensors are designed to accommodate installation angles from 5 to 26 degrees
  • Dorman sensors work with all existing Tire Pressure Monitoring System (TPMS) tools

Rubber (Snap-In) Installation: A rubber-enclosed valve piece is "snapped in" to the body with a valve screw.

Metal Valve (Clamp-In) style TPMS Sensors have higher speed ratings (typically up to 155 mph) than Rubber Valve (Snap-In) styles (typically up to 115 mph).

Metal (Clamp-In) Installation: The valve piece is attached to the sensor body, and the valve core is secured with a nut and rubber grommet.

Program vs. Clone vs. Relearn

Don't confuse TPMS Sensor Relearning, Programming and Cloning! Some processes require a Tire Pressure Monitoring System (TPMS) Programming Tool to complete, but not all processes are required (or available) for every application.

Required only for Universal (Programmable) Sensors, in addition to TPMS Sensor Relearning. A TPMS Tool is required to:
  • Program the specific Year/Make/Model protocol for the vehicle into the sensor
  • Create or Clone a sensor ID onto the sensor


Ideal for drivers who frequently swap wheels/tires, such as during the winter season. A relearn procedure is not required when sensors are cloned. A TPMS Tool is required to:
  • Copy/Clone the unique ID from the original TPMS Sensor to the replacement sensor


Required when a new (not cloned) sensor ID is introduced or when the tires are rotated. A TPMS Tool may be required to:
  • Write the unique sensor IDs to the vehicle's computer
  • Assign the IDs to the correct wheel position (for vehicles that display pressure by location)
