Check Engine or Service Engine Soon Light ON?

Just what is a check engine light and why does it turn on? Consider the check engine light as the sole means your vehicle has of telling you something isn’t right. From a gas cap isn’t screwed on tight, all the way to you need to replace the whole engine.

If either one of these things is happening or anything in between your check engine light can turn on.

Now that we all know it could mean practically anything. Below are a few of the top reasons that your check engine light has turned on. Then how serious it is on a scale from 1-10.

1. Your gas cap is not tight (0)

The fuel system monitors the pressure in the fuel tank. In any event, the pressure is incorrect it can set off the check engine light.

2. Your O2 Sensor must be replaced (2)

The O2 Sensor measures the quantity of oxygen which is not combusted in your exhaust system.

3. Catalytic Converter must be replaced (4)

This helps keeps our world clean by filtering out carbon monoxide going through your exhaust system.

4. Mass Airflow Sensor (4)

This measures just how much air flow is entering the engine to measure how much gasoline is required for your engine to run correctly.

5. Issues with Spark Plugs or Spark Plug Cables (9)

The Spark Plugs task is to light the fuel and air mixture in the combustion chamber. The discharge is given by the cables through the ignition coil and delivers it to the spark plugs.

You can take a deep breath, just because your check engine light is on doesn’t mean it’s more affordable to purchase a brand new vehicle. It means something in your car or truck requires some attention. Yes, it’s possible to be something more serious. However, the most common issues from a check engine light other than a loose gas cap. Are about the same price to repair as one or two car payments.

After I see the check engine light turn on, what is the next step?

"Awesome Service! Been coming to the Care Shop for a few years. They always do great work at reasonable prices. Very honest when needing repairs, never try to sell you more than you need. Mark & Rose are really nice people and have great customer service skills."
Roger M.
"Mark & Rose & co. are just the best in taking care of my car. Mark takes the time to explain what they do, the mechanical aspect, and give me the lowdown if I need to be worried or not. And their prices are reasonable for the through attention they give to my car."
James S.
"My '05 Honda had a bad vibration under acceleration. Mark narrowed it down to ether the transmission or a half shaft. He was reluctant to fix both because of the cost I would incurre. I feel other mechanics wouldn't care and charge me for the biggest profit. Mark replaced the half shaft and problem solved."
Federico C.

"This place did a great job on my old truck. The recommended services were done at a reasonable price and the truck was done when promised. They pickup the phone when you call and have excellent customer service."
Craig B.
"Quality and Honesty exemplified. I find them extremely honest, they diagnosed a problem they thought it was, and then the next morning called me back saying they woke up early and thought about it and it was actually a less pricey issue to fix. I appreciated this because it was a tricky issue, and the initial one would have been costlier, so he was extremely honest. I've recommended them to many people so far."
