If you’ve got a check engine light on in Santa Clarita, the smartest move is a quick, professional scan to see what’s really going on. Below, we’ll break down the most common causes, why ignoring the light is risky, and how a mobile scan from AutoNation Mobile Service gets you answers (and fixes) without a shop visit.
What Triggers a Check Engine Light?
Your car’s OBD-II system logs a specific code when something falls out of range, and then sends a signal to the check engine light (CEL) on your dashboard. Here are some of the most common causes for this:
• Loose or unsealed gas cap
• Oxygen sensor or air-fuel sensor faults
• EVAP system leaks
• Catalytic converter efficiency issues
• Ignition misfires, spark plugs, coils, or wires
• Mass airflow sensor (MAF) or intake air leaks
• EGR system or PCV faults
• Fuel system problems including weak pump, clogged filter, or injectors
•Weak battery or alternator issues
It’s also important to know that a steady CEL signals a stored fault you should check soon, but a flashing CEL usually means an active issue that can damage your engine components and needs immediate attention. If your CEL is flashing, please avoid driving and contact us right away.
Risks of Ignoring the Check Engine Light
- Expensive damage: Misfires can overheat and destroy engine components
- Poor drivability: Stumbling, rough idle, or low power and be annoying and even dangerous in high-speed traffic or freeway merges.
- Poor Fuel Economy: Faulty sensors make the engine run rich, wasting fuel.
- Smog test failure: An active code or incomplete readiness monitors will fail your inspection.
Risks of Ignoring a Check Engine Light
Ignoring your check engine light can lead to significant consequences, including:
- Reduced Vehicle Performance: Ignored issues can diminish your engine’s efficiency and power.
- Increased Repair Costs: Small, manageable problems may evolve into costly repairs if left unresolved.
- Emissions Issues: An active check engine light often signals emissions system malfunctions, potentially causing your vehicle to fail emissions testing.
