Question
What role does the TPMS antenna play in the system?
Answer
It receives RF signals from wheel sensors and forwards them to the ECU for processing.
Explain
Antennas are usually mounted in wheel wells (front/rear) or under the dashboard; their placement affects signal strength (e.g., rear antennas struggle with long-bed trucks). CHEPQ tools test antenna reception (via RSSI) to diagnose “intermittent communication” issues.
