* Check Engine Light: This is the most common car engine light sign. It can be caused by a variety of problems, including problems with the engine’s fuel system, ignition system, emissions system, cooling system, or electrical system.
* Service Engine Soon Light: This light is less serious than the Check Engine Light, but it still indicates that there is a problem with your vehicle’s engine. You should take your vehicle to a mechanic as soon as possible to have the problem diagnosed and repaired.
* Oil Pressure Light: This light indicates that the oil pressure in your vehicle’s engine is low. This can be caused by a leak in the oil system, or by a problem with the oil pump. You should add oil to your vehicle immediately, and then take it to a mechanic to have the problem diagnosed and repaired.
* Coolant Temperature Light: This light indicates that the coolant temperature in your vehicle’s engine is too high. This can be caused by a leak in the coolant system, or by a problem with the water pump. You should turn off the engine and let it cool down, then add coolant to your vehicle. You should also take your vehicle to a mechanic to have the problem diagnosed and repaired.
* Battery Light: This light indicates that there is a problem with the battery or charging system. This can be caused by a loose or damaged battery cable, or by a problem with the alternator. You should check the battery cables and connections, and then take your vehicle to a mechanic to have the problem diagnosed and repaired.

Causes of Car Engine Light Signs

There are a variety of different causes of car engine light signs. Some of the most common causes include:

* Loose or damaged gas cap: A loose or damaged gas cap can cause the Check Engine Light to come on. This is because the gas cap helps to seal the fuel system, and a loose or damaged gas cap can allow fuel vapors to escape.
* Faulty oxygen sensor: An oxygen sensor is a sensor that measures the amount of oxygen in the exhaust gases. A faulty oxygen sensor can cause the Check Engine Light to come on because it can send incorrect signals to the engine’s computer.
* Spark plug wires: Spark plug wires are the wires that connect the spark plugs to the ignition coil. Faulty spark plug wires can cause the Check Engine Light to come on because they can prevent the spark plugs from firing properly.
* Catalytic converter: The catalytic converter is a device that helps to reduce emissions. A faulty catalytic converter can cause the Check Engine Light to come on because it can restrict the flow of exhaust gases.
* Mass airflow sensor: The mass airflow sensor is a sensor that measures the amount of air that is flowing into the engine. A faulty mass airflow sensor can cause the Check Engine Light to come on because it can send incorrect signals to the engine’s computer.
