Check Engine Light Diagnosis

Why come to us if your Check Engine Light is lit

A lit-up “check engine” light can range from meaning that you just need a software update to a major engine issue. This is why it’s important to work with manufacturer trained technicians using a computer-powered shop.  Our technician’s first step is to tap into your vehicle’s software to get an issue code. That guides a deep hands-on diagnosis to find out exactly what’s needed. Every appointment also includes a cleaning inside and a virus-killing germ bath treatment.

The “check engine” light is not something you want lit up. It is a warning that the onboard diagnostics system has detected a malfunction in the vehicle’s emissions, ignition, fuel or exhaust systems. It can be anything from a software issue to loose gas cap or spark plug or something as severe as a faulty catalytic converter or major engine problems.

Don’t ignore it.

The “check engine” light usually comes on for a few seconds every time you start the engine. That’s normal. There’s a problem if it stays on. If the “check engine” light is flashing or blinking then you have a more serious problem that needs to be dealt with right away. You should speak to a technician or service advisor before driving it.

Because the “check engine” light can mean anything from super serious to just a technicality, it’s impossible to estimate cost until the technicians determine what the issue is. As with all work done through CarCare, you’ll have the chance to review and approve any work with pricing before it’s done.
