Reasons A Chevy Check Engine Light May Turn On

There are several issues that may cause your check engine light to come on. While we encourage you to bring your car, truck, or SUV in for a maintenance check up when your check engine light turns on, we want to ensure you are aware of potential issues your vehicle may be having. Below is a list of frequently seen issues that cause the check engine light to illuminate.

• Malfunctioning spark plugs or failed ignition coil: if the spark plugs or ignition coils are not functioning properly, the engine can misfire.
• Loose gas cap: if your vehicle’s gas cap is loose, missing, or damaged, fuel vapors are likely to escape causing the check engine light to turn on.

• Defective oxygen sensor: your engine requires a specific air/fuel mixture which is measured by the oxygen sensor. If the sensor is not functioning properly, your check engine light may come on.

• Obstructed mass air flow sensor: when exposed to polluted air, the sensor can not properly report on the air to fuel balance.

• Obstructed Catalytic Converter: the catalytic converter removes harmful emissions and can become clogged over time causing a decrease in performance.

• Battery or alternator issues: if the battery or alternator are not functioning properly, your vehicle will lack the power it needs to run, which may cause the check engine light to appear.

Your Chevrolet engine is a complex system with many different components. While these common problems may cause your check engine light to appear, there are an array of maintenance solutions. If your check engine light illuminates, we invite you to schedule a service appointment at DeFOUW Chevrolet!
