It's that time of year again: as West Michigan goes through cycles of warm days and frigid nights, fluctuating temperatures can cause small issues to arise in your vehicle. A lot of the time, a check engine light will come on for something insignificant, including faults in the sensors monitoring for issues.

If your vehicle started showing a check engine light recently, it's not always bad news. Oftentimes, a quick check from our highly-skilled technicians is all that's needed. If you do need a repair, our team will ensure it's completed correctly and promptly. Read on for five common causes of a check engine light, then visit the Borgman Service Center for a pre-winter checkup!

Your Gas Cap Is Loose

When customers come in reporting a check engine light in an otherwise healthy vehicle, a loose fuel cap is often the cause. The cap prevents gasoline fumes from escaping the tank and helps the entire fuel system stay at the correct pressure.

If you've discovered your check engine light is on after filling up at the gas station, pull over and check if your gas cap is properly tightened. The light may not go away after fixing the issue, but our technicians will be able to shut it off for you.

Dirty Oxygen Sensors

Most vehicles are equipped with a series of oxygen sensors. These measure the amount of unburnt oxygen in your vehicle's exhaust, and then tell the computer to adjust the fuel/air mixture accordingly. A failed sensor will throw a check engine light, but sometimes all that's needed is a quick cleaning.

An exhaust gas recirculation or EGR valve failure can also produce a check engine light. This valve lowers the amount of nitrogen oxide in your exhaust and can become partially or completely clogged.

Small Vacuum Leak

Every vehicle relies on a series of rubber vacuum tubes to regulate certain functions of the engine. As they age, the rubber hoses begin to crack and let air in or out, but may only do this under certain conditions. Most of the time this produces a rough idle, but strange symptoms that are tricky to diagnose cal also arise. Our technicians have experience finding and replacing damaged vacuum lines quickly.

Failing Spark Plugs & Wires

If your spark plugs are malfunctioning, either from failing wires or the plugs themselves, gasoline vapor is pushed through the exhaust system without being ignited. This is detected by sensors, and can potentially cause dangerous issues like backfiring, or gasoline exploding from the heat inside the exhaust system. It can also cause expensive damage to the oxygen sensors, catalytic converter, and more.

Fortunately, a misfiring engine usually isn't subtle. However, sensors could detect an issue before it becomes major, so bring your vehicle in as soon as possible.

Engine Airflow Issues

Your engine relies on sensors to measure the air and fuel coming into the cylinders are mixed together at the right ratio. This ensures your engine runs cleanly and efficiently.

If one of these ingredients is disrupted, the sensors catch it and alert you via the check engine light. There are two common culprits for airflow issues: your engine air filter being clogged, and a failing mass airflow sensor. Of course, there could be other factors in play. Our technicians will be able to find the cause and resolve it promptly.
