check engine light lighting up on a car dashboard

🚨 Check Engine Light Diagnostics in St. George, UT

Light On? Don’t Panic — We’ll Find the Problem Fast & Fix It Right the First Time

When your check engine light comes on, it could be something simple — or a sign of a serious engine or emissions issue. The key is not guessing. At St. George Auto Gallery Service, we provide fast, accurate, and affordable check engine light diagnostics in St. George, Utah, so you can know exactly what’s going on and what to do next.

We don’t just scan codes and send you out the door — we explain what the codes mean, what triggered the light, and how to fix it based on real testing and experience.

🔍 What Our Check Engine Light Service Includes:

We diagnose engine warning lights for all makes and models, including gas and diesel vehicles, with dealer-level scan tools.

✅ Diagnosis Includes:

Full OBD-II scan for engine trouble codes
Live data testing (sensors, fuel trim, misfire counters, etc.)
Visual inspection of related systems
Component testing if needed (sensors, coils, ignition, EVAP, etc.)
Explanation of the cause, not just the code
A prioritized repair plan (urgent vs. minor)

If your light is flashing, pull over immediately — that indicates a serious misfire or damage risk. A solid light means it’s safe to drive short-term, but still needs attention.

⚠️ Common Causes of the Check Engine Light:

Faulty oxygen sensor (O2 sensor)
Loose or damaged gas cap
Catalytic converter failure
Misfiring spark plugs or ignition coils
EVAP system leak (emissions-related)
Dirty or failed mass airflow sensor (MAF)
Fuel system issues (injectors, pump, pressure sensor)
Transmission-related trouble codes
Wiring or ground issues in the engine control system

Many problems can trigger the light without causing symptoms — but delaying repairs can turn a $150 fix into a $1,500 breakdown.
