Innocent Light, (Potentially) Scary Consequences

What Causes the Check Engine Light

Although the check engine light is frustrating, it plays an important role in informing you when something is wrong with your vehicle — well before something wrong happens. It does this due to the sensors found within your vehicle. These sensors detect irregularities within your vehicle and if it’s severe enough, the sensor will send a signal to your vehicle’s computer system to trigger the warning light.

What makes the light so frustrating is that it can trigger for numerous situations. Despite the broad nature of its design, there are a few things you can look for when the check engine light goes off. Wondering what some of these things are? No worries, The Quiet Zone in Thomaston, CT is here to help you. Here are three things you can look for when the check engine light goes off!

Loose Gas Cap

This is the best case scenario for anyone that has a check engine light go off. If you notice that this is the problem, simply tighten the gas cap or get a new one (many auto parts stores sell this for cheap!). Make sure you drive around for a little bit and stay patient, as the vehicle’s computer system takes a little bit to notice the adjustment.

Bad Spark Plug

Your vehicle’s spark plugs are responsible for starting your vehicle, as they transfer an electric spark to the cylinder to ignite the air/fuel mixture. You’ll notice something is wrong if you have difficulties starting your vehicle or you notice a small jolt in your vehicle’s acceleration. Make sure you visit The Quiet Zone and let our technicians quickly replace those bad spark plugs with new ones!

Failing Catalytic Converter

The catalytic converter is responsible for converting harmful gases like carbon monoxide into relatively harmless emissions. This component plays a big role in the operation of your vehicle and is one of the first things inspected during a smog & emissions test. You’ll notice a malfunction if you see a dramatic decrease in gas mileage or you notice your vehicle won’t move any faster after stepping on the gas pedal.

Like most components, it’s best to bring this issue to the attention of The Quiet Zone’s trained technicians. This piece can be difficult to replace and needs a trained eye in order to properly remove and install a new one.
