Many drivers ignore the tire pressure warning light for days, assuming it’s a simple low-pressure issue or a glitch. But that small dashboard symbol could signal a bigger concern. TPMS is built to notify you of tire pressure changes before they lead to bigger problems. However, the system itself can also malfunction.
When this happens, you don’t want to guess. Japanese Car Masters provides clear and accurate tire pressure monitoring system diagnosis in San Diego, CA, to find out exactly what’s wrong and why. We serve all types of vehicles, domestic, European, Asian, hybrids, and Sprinter vans. With over 40 years of combined experience and ASE-certified technicians, we get to the source of the issue without wasting your time or money.
Our checklist when your vehicle arrives:
A blinking or solid TPMS light doesn’t always mean low pressure. Sometimes, it’s caused by outdated sensors, signal loss, or incorrect settings after tire replacement or seasonal changes. Some vehicles have indirect TPMS that rely on wheel speed, and in those cases, the problem can be hard to spot without proper tools.
We offer full-service tire pressure monitoring system diagnosis in San Diego, CA. Our team uses manufacturer-specific scan tools to check every part of the system, including sensors, control modules, and battery performance. Whether your light is always on, flashing randomly, or disappearing and returning, we take the time to diagnose the real issue.
What you get from our TPMS diagnosis:
We use manufacturer-approved TPMS scan tools, which means every reading is accurate and specific to your vehicle's system. No general resets or guesswork.
Most tire pressure monitoring tests take under an hour. We respect your time and ensure efficient service without unnecessary waiting.
Every car brand has different TPMS needs. We support domestic, hybrid, diesel, and European vehicles with exact-fit diagnostics and updates.
Even if the tires look properly inflated, the sensors may be sending a warning due to slow leaks, old batteries, or internal faults. It's best to get the system checked.
Most TPMS sensors last five to seven years. If they’ve never been replaced or your light keeps coming back on, a full system diagnosis is a smart choice.
