When to Get an Engine Diagnostic
Your vehicle’s engine is a complex system with many interconnected components. When something starts to fail, it often triggers your check engine light or results in performance issues. Running an engine diagnostic scan helps identify problems early, before they become serious. If you’ve noticed anything unusual while driving, it’s time to get your vehicle checked by a professional.
Common Check Engine Light Causes
The check engine light can indicate a wide range of issues, from simple fixes to critical problems. A diagnostic scan helps pinpoint the source so you can take appropriate action.
- Loose or missing gas cap
- Faulty oxygen sensors or mass airflow sensors
- Worn spark plugs or ignition coils
- Emissions or catalytic converter issues
Symptoms of Engine Trouble You Shouldn’t Ignore
Some signs of engine trouble are easy to miss at first but can worsen quickly if not addressed. Listening to your vehicle and noticing changes in how it drives is key.
- Unusual knocking, ticking, or hissing noises
- Reduced acceleration or sluggish engine response
- Poor fuel economy or stalling
- Exhaust smoke or strange smells
- Flashing Check Engine Light
How Diagnostic Scans Help Identify Issues
Modern vehicles are equipped with onboard diagnostics systems (OBD-II) that store error codes. These codes help our technicians zero in on the issue during an engine diagnostic test. It’s a complex, non-invasive way to understand what your engine needs.
- Retrieves specific fault codes from your vehicle’s computer
- Pinpoints electrical circuit or mechanical faults in the engine
- Reduces guesswork and speeds up repairs
