MY CHECK ENGINE LIGHT JUST CAME ON WHAT SHOULD I DO?

Your first step should be to safely pull over to the side of the roadway, put your hazard lights on, turn your engine off and give Gi Automotive Group a call to discuss the details about your car your check engine light warning. With these details, we can assess if you should drive your vehicle into our Beverly Hills automotive repair shop for an immediate check engine light diagnosis or arrange to have it sent to us on a flatbed to avoid potentially further damaging your vehicles engine.

On older luxury or exotic cars, sometimes the check engine light won’t illuminate but you might notice drive-ability issues such as a rough idle, stalling or hesitation when you press the accelerator pedal. If you experience any of these signs please give Gi Automotive Group a call so we can determine if you should continue driving your car or get it to us immediately for service diagnostic testing! 

Some vehicles have a red check engine light which means pull over immediately, turn your vehicle off and get it towed to Gi Automotive Group in Beverly Hills. Some vehicles have a yellow light which is a warning which is safe to drive your vehicle immediately to Gi Automotive Group. Always try to determine if your vehicle was behaving differently while driving prior to the check engine light came on. 

Did you notice any issues accelerating while driving or from a stop? Was your vehicle making any new noises? Did you smell anything out of the ordinary? Visually inspect your gauges. Is your engine temperature operating higher than normal? 

Are there any other warnings on your digital dashboard displays? If you noticed any of these new issues you should call to have your vehicle towed to Gi Automotive Group in Beverly Hills for immediate diagnostics into the CEL problem.

 

TOP 12 REASONS YOUR CHECK ENGINE LIGHT IS ON

The check engine light could illuminate for a number of reasons, the 5 most common being your: 

1. Oxygen sensor failure. Your vehicle has multiple Oxygen sensors that track and monitor the amount of unburned oxygen in your car’s exhaust system. Without fixing a burnt-out oxygen sensor, your vehicle will experience horrible fuel economy, your engine will run hotter and you could risk damaging your spark plugs and catalytic converters.

2. Broken, missing, or loose gas cap. This sounds like an easy one, but even seasoned automotive professionals forgot to securely tighten their gas cap sometimes. On most modern luxury or exotic cars, if you have not tightened your gas cap properly it will send a signal to your car and your check engine light will come on. Others have a specific gas warning light to let you know that your gas cap is loose.

3. Catalytic converter failure. Your catalytic converter is part of your exhaust system that transforms carbon monoxide into carbon dioxide before it leaves your vehicle through the tail pipes. If your catalytic converter is broken, your car will experience poor engine performance, poor fuel economy and will not pass an emissions test. 

4. Mass airflow (MAF) sensor failure. To determine how much fuel is needed to efficiently and properly run the engine, the mass airflow sensor monitors the exact amount of air entering the engine. A damaged, broken or failing mass airflow sensor will lead to horrible fuel efficiency, engine performance and could damage the spark plugs, catalytic converter, and oxygen sensor as your engine will operate at a higher temperature.

5. Spark plugs or spark plug wire failure. The spark plugs and spark wires work together to ignite the air-fuel mixture in the combustion chamber and transfer the spark from the ignition coils to the plugs. Bad spark components also lead to poor engine and fuel performance, as well as damaged ignition coils, oxygen sensors, and could clog a catalytic converter.

6. Ignition coil failure. If one of your ignition coils fails, it won’t send the necessary voltage to the spark plug so it can properly ignite the air/fuel mixture in one of your cylinders. This will cause your engine to misfire (which you might notice prior to your check engine light).

7. Thermostat failure. The thermostat is a small device that sits between the engine and radiator to control the flow of coolant to the engine depending if it’s hot or cold. A thermostat “stuck open” can cause lack of heat from the heating system. A thermostat “stuck closed” can cause the engine to overheat. Both thermostat failures can cause a check engine light.

8. Vacuum hose leak or failure. Every vehicle has vacuum hoses that help lower harmful emissions by routing the fumes as gasoline evaporates through the engine. If you noticed your vehicles idle begins to surge, fluctuate or settle at a higher RPM while driving or at a stop, a vacuum leak could be the culprit that caused your check engine light.

9. Exhaust gas recirculation (EGR) valve failure. This system lowers the amount of nitrogen oxide that comes out of the car’s engine and helps it run more efficiently. The EGR valve can get clogged up or fail entirely which will result in your check engine light.

10. Battery failure. Today’s vehicles rely on precise voltages and electrical signals to monitor everything in your vehicle. Something as simple as your vehicles battery that could be starting to die and need replacing could be the simple problem causing your check engine light to come on.

11. Coolant temperature sensor (CTS) failure. The engine coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant.  Common signs of the CTS failure include poor fuel economy, black smoke coming from the engine, engine overheating, and the check engine light.

12. Improper installation or broken car alarm. Most people don’t realize that an aftermarket car alarm can wreak havoc on your vehicles electrical system it’s not installed properly. Not only can it drain and damage your battery, but it also can trigger the check engine light!
