Question

What is the role of the TPMS valve stem?

Answer

It houses the pressure sensor, allows air flow to the tire, and enables wireless data transmission.

Explain

Valve stems integrate 3 key components: 1) Pressure transducer (measures PSI), 2) Lithium battery (powers transmission), 3) RF antenna (sends data to ECU). CHEPQ valve stems use brass cores (corrosion-resistant) and EPDM O-rings (airtight seal) for long-term reliability.
