Best of all, it’s free! Red on to learn more.
What’s a Trouble Code Anyway?
Today’s vehicles are packed with sensors that monitor everything from fuel mixture to emissions and engine temperature. When something falls out of the normal range, your car’s computer (the OBD-II system) records a “trouble code” and usually turns on the Check Engine light.
Think of it as your car’s way of leaving sticky notes for the mechanic:
-
“Oxygen sensor not happy.”
-
“Gas cap loose.”
-
“Misfire in cylinder #3.”
When we plug in our professional scanner at University Auto, we can read those codes, interpret what they mean, and give you a clear idea of what needs to be done.
Common Reasons The Check Engine Light Comes On
Firstly not every check engine light signal means impending disaster! Some are amazingly easy to fix. Let’s look at come of the most common culprits!
- Loose of faulty gas cap: It is so simple but a gas cap that is not fully tightened often triggers the light because fuel vapors leak out and that confuses the emissions system. Always check this first. it is surprising how often this is the case!
- Oxygen sensor issues: How much unburned oxygen in your exhaust is measured by the oxygen sensor and assists in controlling fuel efficiency. A sensor that fails reduces gas mileage and often raises emissions.
- Faulty catalytic converter: This helps reduce harmful emissions. If failing or clogged-up, the car may fail an emissions test and run in a poor manner.
- Worn spark plugs and ignition coils: Incorrectly fitting spark plugs will cause engine misfire leading to a feeling of the car stumbling and hesitation when it accelerates.
- Mass Air Flow Sensor (MAF) problems: A bad MAF sensor that senses the amount of air entering the engine. You can recognize this from rough handling, stalling or poor acceleration.
- Contaminated or low fluids: A warning light can often be connected to things like coolant temperature and low oil pressure. Remember if you overlook these now it can lead to serious and expensive problems in time.
Why a Free Computer Scan Matters
When that warning light comes on, guessing is never a good plan. Some drivers try to ignore it until inspection time, but the longer you wait, the bigger the risk of:
-
Reduced fuel economy – costing you more at the pump.
-
Damage to expensive parts like the catalytic converter.
-
Unexpected breakdowns on I-17 or Route 66.
