Before we dive into specific costs, let's briefly go over some of the most common car dashboard warning lights:

• Check Engine Light: Indicates a potential problem with your engine. The cost to diagnose and fix this can vary widely based on the issue.

• Oil Pressure Warning: If this light comes on, it's critical to pull over immediately as low oil pressure can lead to engine damage. The cause and cost of repair will depend on the situation.
• Battery Voltage Warning: This light indicates a problem with your battery or charging system, which could range from a simple jump start to a new alternator costing CAD $500-$1,000.

Basic Light Check: From CAD $50-$100

When you notice a warning light on your dashboard, the first step is usually to have it checked by a professional. This can be done at most auto repair shops and typically costs between CAD $50 and CAD $100. The mechanic will use diagnostic tools to determine what the warning light is for and if there's an immediate risk to your vehicle.
