Top 5 Reasons Your Check Engine Light Is On

Damaged, loose, or missing gas cap. Gas caps wear out over time and need to be replaced accordingly. Does your gas cap not quite tighten (click, click, click) like it use to? Do you smell gas? Is your Check Engine Light on? The gas cap plays an important role in the operation of the vehicle’s EVAP (Evaporative Emission Control) system. It helps capture and reuse fuel vapors from the gas tank that would otherwise be released into the atmosphere. A sealed fuel system requires a properly working gas cap. When the tank is open to the environment, your engine’s emissions can increase and fuel economy can decrease.

Faulty, inoperative, damaged oxygen sensors. Oxygen sensors on most modern day vehicles need to be replaced between 85,000-110,000 miles. The most common signs that pinpoint a faulty oxygen sensor include: Check Engine Light comes on, poor gas mileage & a rough idle. The PCM (computer) uses the oxygen sensors to help calculate the correct air to fuel ratio for your engine hence the importance of properly working O2 sensors.

Bad, damaged (melted), faulty catalytic converter(s). Is your vehicle misfiring, suffering from reduced performance (like it doesn’t accelerate when you step on the gas), experiencing reduced fuel economy, running at a higher temperature, is your Check Engine Light on? These could all be signs of a failing or failed catalytic converter(s). Your catalytic converter helps protect our environment by converting harmful carbon monoxide gasses into carbon dioxide gasses hence the importance of properly functioning catalytic converters.

Are you looking for a shop that offers catalytic converter replacement near me or maybe a local repair shop that knows how to properly diagnose a catalytic converter problem? Plainfield-Naperville’s Team Last Chance Auto Repair has you covered.

Dirty, unplugged, faulty mass air flow sensor. Are you experiencing reduced performance, poor fuel economy and or is your Check Engine Light on? This can mean your having a mass air flow sensor problem. Faulty mass air flow sensors can damage spark plugs, O2 sensors and or the nearly infamous, costly, catalytic converter(s). Your mass airflow sensor measures the amount of air entering the engine to determine how much fuel is needed to run your engine efficiently hence the importance of a properly functioning mass air flow sensor.

Vehicle in need of a tune up (plugs & wires). Does your vehicle need a tune up? Has your vehicle been experiencing poor performance, reduced power or reduced fuel economy? Is your vehicle’s engine misfiring or Check Engine Light on? Your spark plugs ignite the air/fuel mixture in the combustion chamber in your vehicle’s engine. The spark plug wires (ignition cables) deliver the spark from the ignition coil to the spark plugs. These components are supposed to be changed accordingly based off of your vehicle’s maintenance schedule aka mileage. Are you due for a tune up? Last Chance Auto Repair has you covered.
