TPMS sensor service best practices:

Always work with the most recent tool software. Out-of-date TPMS tool software is the most frequent cause of relearning issues.
Use only TPMS-specific service kit parts. Never use a standard brass valve core in a TPMS sensor.
Always use new TPMS service kit parts. Never reuse service parts that have been previously installed.
Always use a torque tool to tighten sensor hex nuts or other threaded TPMS components to proper specifications.
TPMS sensors only need to be replaced if they’ve been damaged, or if the battery is worn out.
Always check the spare tire to determine if it’s TPMS-equipped and working properly.
Replacement TPMS sensors must be relearned to the vehicle, plus a relearn may also be required after performing a tire rotation.
When working on any service that uncovers a control unit or wiring, carefully seal the components to protect them from moisture or chemical exposure. If they are not protected, TPMS sensors can experience problems, including inaccurate pressure readings.
