What the Check Engine Light Really Means
Your check engine light (CEL) is part of your vehicle’s Onboard Diagnostic System (OBD-II). It monitors everything from the fuel system and ignition timing to exhaust emissions and sensor performance.
When the system detects something outside normal operating parameters, it stores a fault code and activates the CEL on your dashboard. These issues can range from a loose gas cap to a failing oxygen sensor or catalytic converter.
Common Causes of a Check Engine Light
The light can illuminate for many reasons, including:
Faulty oxygen (O₂) sensor or mass air flow (MAF) sensor
Loose, damaged, or missing gas cap
Misfiring spark plugs or ignition coils
Catalytic converter inefficiency
Vacuum or intake leaks
Fuel injector or fuel pump issues
Hybrid battery or emissions system faults
Whatever the cause, our technicians perform a full diagnostic scan and verification test to determine the exact problem — not just the code.
Flashing vs. Solid Check Engine Light
Flashing Check Engine Light
This indicates a serious engine misfire or system failure that can cause damage to your catalytic converter. Stop driving immediately and have your vehicle towed to our shop for inspection.
Solid Check Engine Light
This usually means a non-urgent issue that still requires attention, such as a sensor malfunction or emissions fault. You can continue driving but should schedule a diagnostic appointment soon to prevent further problems.

Check Engine Light FAQs – Hash Imports of Fishers, IN
Do you specialize in check engine light diagnosis for import vehicles?
Yes — Hash Imports provides accurate diagnostics exclusively for European and Asian vehicles, including Audi, BMW, Mercedes-Benz, Lexus, Toyota, Honda, Subaru, Mazda, and Volkswagen. Our ASE-certified technicians use factory-level diagnostic tools to identify the cause of your check engine light quickly and precisely.
Do you inspect check engine lights on diesel, EV, or hybrids?
No — Hash Imports does not inspect or diagnose check engine lights on diesel, fully electric (EV), or hybrid vehicles. We specialize in gasoline-powered import vehicles and provide precise diagnostics for check engine lights and related performance issues on those models only.
What does the check engine light mean?
Your check engine light (CEL) is part of your vehicle’s Onboard Diagnostic System (OBD-II). It activates when the computer detects a problem with your engine, emissions, fuel, or ignition systems. The light can indicate a minor issue like a loose gas cap or a serious problem like a failing catalytic converter.
What’s the difference between a flashing and a solid check engine light?
- Flashing Light: This indicates a severe issue, often an active engine misfire that can damage the catalytic converter. Pull over safely and schedule service immediately.
- Solid Light: This typically means a less urgent problem, such as a sensor fault or emissions issue. It’s safe to drive short distances, but schedule an inspection soon to prevent further damage.
Can I still drive my car when the check engine light is on?
If the light is solid, you can usually continue driving — but you should schedule diagnostics as soon as possible. If it’s flashing, do not continue driving. A flashing CEL signals a severe issue that can cause expensive damage if ignored.
What are the most common reasons for a check engine light?
Some of the most frequent causes include:
- Loose or missing gas cap
- Faulty oxygen (O₂) or mass air flow (MAF) sensor
- Failing ignition coil or spark plug
- Catalytic converter efficiency problem
- Vacuum leak or intake air imbalance
- Fuel system issue (injector, pump, or regulator)
- Hybrid or emissions system malfunction
Our technicians perform full system scans to identify the specific fault and its cause.
Can a loose gas cap cause the check engine light to come on?
Yes — a loose or damaged gas cap is one of the most common reasons the CEL illuminates. It can cause a drop in fuel tank pressure, triggering an emissions-related fault code. Tightening or replacing the cap may resolve the issue, but if the light stays on, schedule a diagnostic test.ely and accurately, following manufacturer-specific service guidelines.
How do you diagnose a check engine light?
We use manufacturer-specific diagnostic scanners to read stored fault codes from your vehicle’s computer. Then we perform live data monitoring to track sensor activity, followed by mechanical and electrical testing to confirm the exact cause before recommending repairs.
Can you diagnose hybrid and plug-in hybrid systems?
Yes — our ASE-certified technicians are trained to diagnose hybrid and plug-in hybrid vehicles, including faults in hybrid batteries, inverters, and high-voltage cooling systems. We follow manufacturer-specific safety and diagnostic procedures for every model we service.
