TPMS Diagnosis: Understanding the Warning Signs

When your Tire Pressure Monitoring System (TPMS) light illuminates, it’s crucial to understand the cause to ensure your safety and vehicle’s optimal performance. Here’s a breakdown of common TPMS issues and how to diagnose them:

1. Low Tire Pressure:

• Symptom: TPMS light remains illuminated.
• Diagnosis: Check tire pressure with a reliable gauge. Inflate tires to the manufacturer’s recommended pressure.

2. TPMS Sensor Malfunction:

• Symptom: TPMS light flashes for a short time and then remains illuminated.
• Diagnosis: Requires a TPMS diagnostic tool to identify the faulty sensor.

3. TPMS System Malfunction:

• Symptom: TPMS light may flash or remain illuminated, or the system may not function at all.
• Diagnosis: Requires a thorough inspection of the TPMS system by a qualified technician.

4. Damaged or Missing Sensor:

• Symptom: TPMS light may remain illuminated or the system may not function.
• Diagnosis: Visual inspection of the tire valve and sensor.

5. Recent Tire Service:

• Symptom: TPMS light may remain illuminated after tire rotation, replacement, or repair.
• Diagnosis: The TPMS system may need to be reset. Consult your vehicle’s owner’s manual or a qualified technician.

Remember:

• Regular Tire Pressure Checks: Even with a TPMS, it’s crucial to regularly check tire pressure with a gauge, especially before long trips or in extreme weather conditions.
• Professional Diagnosis: If you’re unsure about the cause of the TPMS warning light, consult a qualified technician for proper diagnosis and repair.
