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)



ACDelco TPMS Sensor Program

ACDelco Quality

ACDelco breaks down their premium portfolio of Original Equipment and Aftermarket parts into two tiers: GM Original Equipment and ACDelco Gold.

GM Original Equipment parts are the true OE parts installed during production or validated by GM—designed, engineered, and tested to rigorous standards and backed by General Motors.
ACDelco Gold parts are the high-quality alternative to OE parts, manufactured to meet GM expectations for fit, form, and function and backed by General Motors.

Attention EU customers: TPMS Sensors transmit at 433 MHz in the European Union - this sensor transmits at 315 MHz and will not work on vehicles operating within the EU. Select a '433 MHz' replacement under your vehicle, or check for universal replacements under Tools & Universal Parts > Wheel > Tire > Tire Pressure Monitoring System (TPMS) Sensor.
