Engine Diagnostics
Advanced technology meets experienced mechanics to solve your check engine light mysteries.
Don't Ignore That Light
The check engine light isn't just an annoyance—it's your vehicle's way of telling you something needs attention. Modern cars have sophisticated computer systems that monitor everything from emissions to engine performance. When something's off, the computer stores a trouble code.
Our shop uses professional-grade diagnostic equipment that reads these codes and gives us detailed information about what's happening under the hood. We'll explain what triggered the light, whether it's urgent or can wait, and what your options are.
Common causes include a loose gas cap, oxygen sensor issues, catalytic converter problems, or engine misfires. Some are quick fixes, others need more attention—but we'll always give you the straight story.

Common Check Engine Light Causes
These issues trigger the check engine light most often.
Loose or Damaged Gas Cap
Simple fix—sometimes the cap just needs tightening. But damage or worn seals can cause fuel vapor leaks.
Oxygen Sensor Failure
Measures exhaust oxygen content. A failed sensor reduces fuel efficiency and can damage the catalytic converter.
Failing Catalytic Converter
Often a downstream issue from other failures. Causes poor performance and can be expensive to replace.
Mass Air Flow Sensor
Measures air entering the engine. Dirty or failing sensors cause poor acceleration and rough running.
Frequently Asked Questions
Common questions about engine diagnostics.
It depends. If the light is steady, the issue may not be urgent but should be checked soon. If it's flashing, that's a warning of a severe problem—stop driving immediately and have it towed. A flashing light often indicates an engine misfire that can cause catalytic converter damage.
Intermittent issues are common and can be tricky to diagnose. The code is stored in the computer's memory, so we can usually retrieve it even after the light goes off. Conditions like heat, vibration, or specific driving patterns can trigger the light temporarily.
Basic code readers show the code number but not the detailed data that professional scanners provide. Our diagnostic equipment can access manufacturer-specific data, live data streams, and perform specialized tests that give us a complete picture of what's happening.
Basic code reading takes 15-30 minutes. Full system scans and performance diagnostics typically take 1-2 hours. If we find issues that need further diagnosis, we'll give you a time estimate before proceeding with any repairs.
