When your check engine light turns on, it’s your car’s way of saying something needs attention. At Holm’s Mechanical near Burnaby, BC, our certified technicians use advanced diagnostic tools to find the trouble codes behind the light, determine the issue, and fix the problem before it leads to more expensive repairs.
Whether it’s a minor issue like a loose gas cap or a serious engine problem, it’s important to pay attention to this critical warning sign.
What Does the Check Engine Light Mean?
Your check engine light, also known as the malfunction indicator lamp (MIL), is part of your vehicle’s control system. When it lights up, your car’s computer has detected an issue that could affect engine performance, the emissions system, or other vital components.
The light may come on in two ways:
- Steady glow: Indicates a non-urgent issue, but still requires service soon.
- Flashing check engine light: Signals a more serious engine problem—stop driving and get it checked immediately.
Common Reasons the Check Engine Light Turns On
There are many possible causes behind the light. Some are simple to fix, while others need professional attention. Common triggers include:
- Loose gas cap: A common and easily fixed issue that can affect fuel pressure and emissions.
- Faulty oxygen sensor: Impacts fuel mixture and can harm your catalytic converter if ignored.
- Worn spark plug or plug wires: Leads to poor engine performance and reduced fuel economy.
- Malfunctioning mass airflow sensor: Affects air intake and engine power.
- Failing catalytic converter: A critical part of the exhaust system that controls emissions.
These components all work together to ensure your car runs efficiently. Ignoring the light could lead to engine misfires, poor fuel economy, or even engine damage.
What to Do When the Engine Light Is Flashing
If your engine light is flashing, it’s a sign of a severe issue—often a misfire that could damage the catalytic converter. You should:
- Pull over safely and turn off the engine.
- Avoid driving until a professional can inspect it.
- Call Holm’s Mechanical for immediate service.
Driving with a flashing light could cause further damage to your exhaust system, control system, or internal engine components.
How Holm’s Mechanical Diagnoses the Problem
At Holm’s Mechanical, we use advanced diagnostic equipment to read your vehicle’s trouble codes. These codes pinpoint the area or component at fault, allowing us to quickly locate and fix the problem.
Our diagnostic process includes:
- Reading the malfunction indicator lamp (MIL) codes
- Testing affected sensors and circuits
- Inspecting related parts like spark plugs, plug wires, and sensors
- Checking engine performance and emissions
- Confirming repairs clears the issue and resets the system
We don’t just turn off the light—we solve the root cause.
Can You Check the Codes at an Auto Parts Store?
Some auto parts stores offer free code readings, but their tools only show the code, not the whole story. For example, a code might point to the oxygen sensor, but the real issue could be elsewhere in the control system or emissions system.
At Holm’s Mechanical, we combine code readings with professional inspections and tests, so you get accurate answers and reliable repairs.
Don’t Ignore Warning Lights
Your dashboard has many warning lights, but the check engine light is one of the most important. It monitors everything from the exhaust system to the mass airflow sensor. Even if the car seems fine, ignoring it can lead to:
- Reduced fuel economy
- Damage to the catalytic converter
- Engine misfires or stalling
- Higher emissions
The earlier you bring your vehicle in, the easier and more affordable it is to repair.
Preventing Future Check Engine Light Problems
Routine maintenance can prevent many causes of a check engine light. To keep your vehicle running smoothly, Holm’s Mechanical recommends:
- Replacing spark plugs and plug wires as scheduled
- Keeping your air filter and mass airflow sensor clean
- Checking the gas cap for tightness after fueling
- Inspecting the exhaust system for leaks

These small steps can protect your engine and help avoid unexpected issues.
