Most common questions used to investigate
Check the fuel cap. Is it tightly closed?
Were you driving at a high speed when suddenly the light turned on?
Is the car having problems with power, such as suddenly losing power or not revving up properly?
Is your car burning more fuel than usual?
Does your car suddenly stall or have trouble starting, or do you experience a sudden change in the position of the throttle pedal when driving?
Did you recently get an aftermarket alarm installed?
Does your car's idle rpm dial surge or settle at an unusually high rpm?
Is the car's battery dead or running on its last leg?
Common conclusions
Close the cap and tighten it again. Keep in mind that it may take several drives before the engine light turns off.
It is better to reduce the speed of the car as the engine might be under pressure due to the increased speed. It is advised to get the car checked by a technician to prevent any damage.
The check engine light in this case might be due to a bad spark plug or ignition coil. It is advised to get the car checked by a technician to prevent any damage.
The problem may be a faulty oxygen sensor. The oxygen sensor measures the amount of uncombusted oxygen and sends the data to the car's computer, which uses it to regulate the mixture of air and fuel that enters the cylinders. The car will still keep on running but it might damage other components in the long run, so it is advised to get the car checked by a technician to prevent any damage.
The problem may be with the mass airflow sensor which monitors how much air enters the engine. You should get the car checked as this could lead to problems such as sudden stalling or power fluctuation.
Get the alarm checked as an alarm that has not been installed properly can drain the battery or stop the car from powering up. The engine light will also get triggered in such a case.
The problem may be with a leak in the vacuum which performs a variety of functions such as boosting the operating capacity of brakes and lowering harmful emissions, so it is advised to get the car checked by a technician to prevent any damage.
The engine light might be triggered due to a dead battery. So get it checked and replaced as a dead battery can cause many more problems.
We could not determine the cause of the problem. Call your mechanic and get your car a full or partial diagnosis.
