Step-by-Step Diagnostic Procedure

  1. Scan TPMS module for sensor IDs and status

  2. Check which sensor is not reporting

  4. Verify sensors were relearned after recent tire service

  5. Inspect sensor for physical damage

Frequently Asked Questions

How long do TPMS sensor batteries last?

TPMS sensor batteries typically last 5-10 years or 50,000-100,000 miles. Once the battery dies, the entire sensor must be replaced as the battery is sealed inside.

Why does my TPMS light flash then stay on?

A flashing TPMS light that then stays solid indicates a system fault, usually a failed or unresponsive sensor. A steady TPMS light without flashing typically means low tire pressure.

Can I replace a TPMS sensor myself?

The sensor itself requires removing the tire from the wheel. However, some vehicles allow DIY sensor relearn procedures using a TPMS tool or specific button sequences on the vehicle.
