Question
How do you test a TPMS sensor without installing it?
Answer
Use a CHEPQ sensor activator to wake it, then read RF data with a scanner.
Explain
The activator sends an LF signal to wake the sensor; the scanner reads ID, pressure, temperature, and battery voltage. This lets technicians test sensors before installation, avoiding rework.
