Check Engine Light Service

At Roy’s Service Centre in Laurel, ON, we know how frustrating and worrying it can be when your car’s check engine light turns on. Our team of skilled technicians is here to help with top-quality check engine light service. We want to make sure your vehicle runs its best and gives you peace of mind while you’re driving.

What Causes the Check Engine Light to Turn On?

The check engine light, sometimes called the CEL, is an important warning that something might be wrong with your car. Many things can cause it to turn on, from minor to serious issues. Some common reasons include:

Evaporative Emissions: Problems with the emissions system can make the check engine light come on. This might mean there’s a leak or something isn’t working right in the fuel vapour control system.

Faulty Gas Cap: A loose or broken gas cap is a common reason for the check engine light to turn on. Even though it’s a small part, it’s necessary for keeping the pressure right in the fuel system. If it’s not secured properly, it can trigger the light.

Ignition System: Issues with parts like spark plugs or ignition coils can cause misfires, which might turn on the check engine light. Ignoring these problems could hurt your engine and make it perform poorly.

Emissions System Trouble: Problems with parts like the catalytic converter, oxygen sensor, or mass airflow sensor can also trigger the check engine light. It’s important to deal with these issues quickly to meet emissions rules and keep your engine running well.

How Do We Figure Out What’s Wrong?

When you bring your car to Roy’s Service Centre for help with the check engine light, our experienced technicians use advanced diagnostic tools, like OBD II scanners, to find out what’s going on. Here’s what we do:

Reading Engine Codes: We use OBD II scanners to read the diagnostic trouble codes (DTCs) stored in your car’s computer. These codes tell us which systems or parts are having issues.

Visual Inspection: Our technicians look closely at parts like the engine, exhaust system, and fuel cap to see if there are any obvious signs of damage or wear.

Testing Parts: We test important parts like the oxygen sensor, catalytic converter, and ignition system to see if they’re working as they should.

Understanding Data: Our team looks at all the diagnostic information we’ve collected to figure out exactly what’s causing the problem and decide on the best way to fix it.

What Should You Do If Your Check Engine Light Is Flashing?

If your check engine light is flashing, it means there’s a serious problem that needs immediate attention. Ignoring it could cause considerable damage to your engine and be dangerous. Here’s what we suggest:

Safety First: Pull over somewhere safe and turn off your engine. Don’t keep driving to avoid making things worse.

Schedule Service: Call us right away to set up a time to bring your car in for a check engine light service. We’ll make sure to look at it as soon as possible.

Drive Carefully: If you have to keep driving to get to us, try not to accelerate too hard or carry heavy loads. This can help keep your engine from getting even more stressed.

Trust the Technicians: Let our skilled technicians diagnose and fix the problem causing the flashing check engine light. Following their advice means your car will get the right repairs to run well and be safe.

Our Customer Reviews

Always friendly, efficient. They really care about giving good service and about their customers.

Donald Wale Nov 11, 2021

Very good customer service.

Elisia Fendley Oct 10, 2025

I found Roy’s to be extremely trustworthy and offer quality service. Before I moved to this area over 26 years ago, I had heard of Roy’s. I have never been disappointed nor will you👍😎👏 Most recently I experienced a situation where extensive trouble shooting led them to replace a part which was important. The process was transparent and fully covered under warranty. Once again my highest recommendation to the staff and management at Roy’s.❤️

Trent Pilling Sep 9, 2025

Everyone there is very knowledgeable, friendly and courteous. They take the time to explain everything that needs to be done and lets us know what we have to watch for, for the future that may need to be done. They give you a written, detailed estimate for the work and if they get to something on the list that isn't needed to be done, they don't do it. It saves us putting out extra money. They are very honest people.

So I was on my way up north on vacation when the car broke down. At the mercy of local mechanics to get things back up and running. Well luckily it was Roy's who was the closest shop. Fox was professional from the start, quick service, detailed explanation, proper inspection. Service delivered as promised with a fair price. Fox knows his stuff . Very friendly as well. If I ever am in the area and need Service I will definitely return. If i lived up there I would take my car there regularly. Thanks team for making things as smoothly as possible . Keep up the good work Cheers

Brought in my work truck for a quick tire repair and the manager fit me in right away. The mechanic working on my truck was thorough and very nice, he showed me the work that needed to be completed from the 3" carriage bolt stuck in my tire, i thought i was going to have to get a new tire but they were able to save this one. pricing was very reasonable, just from the rapid service and the knowledgable staff this will be my new "go to" service centre. thanks Roy's Service Cntr!!

Professional service delivered on time and on budget, overall great experience.

Ian Bradley Amos Feb 2, 2023

I’ve been burned by seeking out the “cheapest” mechanic. Then I found Erskine’s in Orangeville and they were great, but a little far to get to. Then I found out Roy’s was the same owner! The Napa warranty gives me peace of mind. And their turnaround time is reasonable and their online inspection report is informative and helpful. Great customer service as well. I highly recommend Roy’s and Erkine’s.
