Understanding The Engine Check Warning Light

Understanding the Engine Check Warning Light

When your car’s check engine light turns on, it can be concerning for car owners. However, it’s important to understand that the engine light could indicate a variety of engine problems. At Prospect Lake Auto Care in Victoria, BC, we help car owners diagnose and fix these issues to ensure their vehicle runs smoothly. Here’s what you need to know about the check engine light and how to address it.

What Causes The Check Engine Light To Turn On?

The check engine light is part of your vehicle’s diagnostic system and is linked to a variety of components. It monitors the performance of crucial systems like emissions, spark plugs, oil pressure, and more. When there’s a problem with one of these systems, a warning light will turn on, signaling that it’s time to take your car to a trusted auto repair shop.

Here are some of the common causes:

  • Loose Gas Cap: One of the simplest causes for a check engine light is a loose or damaged gas cap. A loose gas cap can cause your car’s emissions system to register a leak, triggering the engine light. It’s an easy fix – simply tighten or replace the gas cap.
  • Emissions System Issues: Problems with your car’s emissions system, such as a faulty catalytic converter or oxygen sensor, can cause the engine light to illuminate. These parts are responsible for reducing harmful emissions and ensuring your car runs efficiently. If the engine light is flashing, it could indicate a more serious issue with the emissions system.
  • Spark Plugs: Spark plugs are essential for igniting the fuel in your engine. If they are worn or malfunctioning, they can cause engine misfires, which can turn on the check engine light. Replacing spark plugs is often a part of routine maintenance.
  • Oil Pressure: If the engine light is flashing, it could indicate low oil pressure, which can lead to severe engine damage. Oil is necessary for lubricating your car’s engine components. If you see this warning, it’s essential to get your oil levels checked immediately.
  • Mass Airflow Sensor: The mass airflow sensor measures the amount of air entering your engine. If it becomes faulty, it can cause poor engine performance and trigger the engine light.
  • Diagnostic Trouble Codes: The onboard diagnostics system in your car records trouble codes when something goes wrong. These codes can help auto technicians pinpoint the exact issue. Diagnostic trouble codes (DTC’s) are essential for fixing the problem efficiently.

What To Do When The Engine Light Turns On

If the check engine light comes on, it’s important not to ignore it. A flashing engine light signals a more serious issue that could lead to further damage. Here’s what you should do:

  • Check for Simple Issues: Start by checking if the gas cap is loose. If you find that it’s not tightened, secure it and see if the warning light turns off.
  • Pay Attention to the Warning Light: If the engine light is flashing, it often indicates a more urgent issue that needs immediate attention. You should stop driving and have the car inspected by a professional mechanic.
  • Get a Diagnostic Check: At Prospect Lake Auto Care, we use advanced diagnostic systems to read the trouble codes from your car’s onboard diagnostics (OBD). This helps us understand exactly what’s going wrong. Whether it’s a spark plug issue, oil pressure problem, or malfunctioning oxygen sensor, our skilled technicians will identify and fix the problem quickly.

Why Regular Maintenance Is Important

Routine maintenance is the key to keeping your car in good shape. Regular inspections can help catch potential issues before they become major problems. For example:

  • Changing Spark Plugs: Spark plugs wear over time, and replacing them at the recommended intervals helps keep the engine running smoothly.
  • Emissions System Checks: Regularly inspecting the catalytic converter and oxygen sensors ensures that your emissions system is working correctly, reducing the chances of a check engine light turning on.
  • Oil Changes: Maintaining proper oil levels is crucial for the health of your engine. Neglecting oil changes can lead to oil pressure issues and damage to internal engine components.

Our Customer Reviews

Excellent customer service from Colin who fit me in last minute for a repair

Phil Bowers Sep 9, 2025

Great people. They were able to fit in an appointment for the very next day of my call because my car needed urgent attention. Honest and proper workmanship.

Kerem Işık Sep 9, 2025

What amazing service! Gary was fabulous! He managed to fit us in for a vehicle inspection with little notice. The vehicle inspection results were emailed to us so that we now have an electronic record for our files. The inspection report was extremely thorough. Ten out of ten guys! On one final note, the other guy in the office also told us that we should do an online search to see if there are any liens, accidents, etc. reported on the car. Of course, we folled his advice, but how decent of him.

M D Jul 7, 2025

Lost my brakes on my Ford F-350 coming down from Heartland and Prospect Lake took care of me and my daughter right away. Great service as they also did a follow-up inspection and fix on the pads months later!

Kael Campbell Jul 7, 2025

Fair prices, good service.

Best service you can trust. Refreshing experience

Brad Dyrbye Apr 4, 2025

Had a great experience at Prospect Lake Auto Care getting my front brake pads and rotators replaced! Mike was wonderful to work with and the service was reasonably priced. No hidden fee's and a transparent quote provided over the phone prior to receiving service. Mike even followed up via text the next day to ensure I was satisfied with the work completed. I highly recommend Prospect Lake Auto Care!!

Stephanie Duncan Mar 3, 2025

I ended up taking my 2019 Porsche Macan to Prospect Lake Autocare after I received a ridiculously high quote to service my car from the dealer. Shannon was extremely efficient, booked me in for the following week and provided a courtesy car for the day. The service fee was reasonable and they also included a detailed inspection report. I paid a fraction of what the dealer quoted! Really happy with the experience and I’ll be returning for future service!

Julie Watkins Feb 2, 2025

I pulled into this shop unexpectedly with no appointment on a random day with a very low back tire. I chatted with the receptionist who was the most friendly kind lady ever and got the guys in the shop to take a look almost immediately. They identified the issue as my valve stems and offered to replace them right on the spot for no cost I couldn’t be more thankful for this shop as I was battling with kal tire for a long time who ultimately led me to this problem 😅 this company had my back and got them fixed in not even a bit over 30 mins. They are truly reliable and i could only imagine they succeed with full effort in all their other services:) thank you prospect

Volkswagen needed alternator work. Good honest mechanic. Wish they were all like this.

Josh C Mar 3, 2024

I was recently referred to Prospect Lake Auto for diagnosis/repairs on my Jeep. I was told that “Mike” @ Prospect was the S. Island all-things-Jeep guy and I was not disappointed! Within seconds of looking under the hood he found the problem. He knew exactly where to look and explained to me in detail what was going on. I booked in to have the repairs done and my experience with Mike as well as Shannon (who takes care of all logistics… I’m thinking she basically runs the place lol) was exceptional. Highly skilled, organized, friendly and knowledgeable folks at Prospect Lake Auto. I highly recommend this place!

Kat Hinter Mar 3, 2024

Barbara Belknap Jan 1, 2024

The service here was wonderful! Came recommended from a friend. They were upfront about when they could get it in, they delivered within that time, helped me sort out transport, and fixed an the issues I had at a reasonable cost. The owner is local and the communication was great. They have loaner cars available (one wasn't available to me at the time) but they offered to work around the loaner car schedules. This is my new place to have my car serviced. Plus it's right across from a nice cafe.

Selina McGinnis Jan 1, 2024

As always; fabulous, prompt, effective and reasonably priced services. Excellent!

Holly Lee Nov 11, 2023

Mike & the crew rescue me & my Fiat every time… reminding me that I am not driving a four wheel drive off-road vehicle….

Bill Milliken Aug 8, 2023

I had a flat tire emergency on vacation in Victoria and had to get to a ferry to get home. I called these guys and they took it in right away and I made my ferry. I am an auto shop owner so I know this was a sacrifice for them as they wouldn't have any real future relationship with me and a flat repair isn't exactly a big money maker. But they did it with a smile and their tech was very particular about wheel lug torque specs and tire pressures (again: I have inside knowledge). I don't write reviews but these guys deserve it. Character First - that's what they were. Thank you!

Damian Shaw Nov 11, 2023

My Bmw randomly stopped running in the middle of nowhere, i came across the only place for miles. Parts were hard to get but Mike gave me a loaner for a few days til it was fixed. Even the shops where ive bought brand new cars from didnt supply a car while mine was being fixed. More than happy with his price and his customer service was great

Brandy Buchan Nov 11, 2023

Great service, great people, professional work. Highly recommend!

Luke Davison Oct 10, 2023

Fantastic service that’s always friendly and dependable. I am not a car person and I feel very safe brining my vehicle to prospect lake auto because I know they are never going to over sell me services I don’t actually need. I really feel like family. Thank you!

Tamara Monod Oct 10, 2023

Prospect Lake auto is my go to for maintenance and repairs. They are kind, helpful, and prompt.
