Why Check the Engine Light on in Hyundai
Gas Cap:
Your cap is not tight, damaged, or broken. This can lower fuel pressure and let fuel vapors escape, decreasing fuel efficiency and reducing harmful emissions.
Catalytic Converter:
These substances can build up in the catalytic converter and block the flow of exhaust gases, which can lead to some problems:
- Reduced engine power
- Increased fuel consumption
- Engine misfires
- Failure to pass emissions tests
Faulty Spark Plugs or Spark Plug Wires or ignition Coils:
Over time, you will need new spark plug coils or wires. Spark plugs create a spark that starts your engine. Spark plugs generate a spark to initiate your engine. If the plugs do not spark enough, your engine might misfire, reducing fuel efficiency and performance, or it may not start.
Oxygen Sensor:
If your oxygen sensor is exposed to hot exhaust gas for a long time, it may need to be replaced. The oxygen sensor gives the car’s computer important information about the air and fuel mixture. If the oxygen sensor is not working properly, the computer may give the engine too much or too little fuel. If the engine gets too little fuel, it could stop working completely. A faulty oxygen sensor causes the car to use too much fuel. It will produce a lot of smoke and smell bad.
Faulty Camshaft:
A camshaft is a critical component of your car’s engine. It is responsible for opening and closing the engine’s valves, allowing the engine to breathe and run properly. If the camshaft is faulty, it can cause problems with your car’s engine.
A faulty Crankshaft:
This serious problem can cause many issues with your car’s engine. If the crankshaft is defective, it can cause the engine to misfire, run rough, or even stall and the Check engine light can indicate in your car dashboard. The crankshaft is a critical component of the engine, and it is responsible for converting the up-and-down motion of the pistons into rotational motion.
Speed Sensor Faulty:
A speed sensor is a device that measures the rotational speed of a shaft or wheel and sends the signal to the computer. If the vehicle speed sensor stops working, this may affect the following component.
- Anti-lock braking system (ABS)
- Electronic stability control (ESC)
- Transmission control system (TCS)
- Odometer
