What Makes the Check Engine Light Come On?

Your car’s check engine light is one of the best tools available when it comes to diagnosing problems with the vehicle. In fact, it can even catch some problems before they get worse. Therefore, you need to at least know how to interpret what it says. Even if you do plan on taking your car to a good autoshop in Cathedral City like Davies Auto Care, having an idea of what’s wrong with your car can help make the shop visit faster.

The Check Engine Light Is On When…

When the check engine light is on, there are three main reasons why this could be happening:

1) The car has a problem that needs repair.

2) You have a malfunctioning sensor or component.

3) A code has been set for the computer.

If you’re not sure whether your car is experiencing any problems, then it may be time to take it into a garage and let them look at it.

How Does the Check Engine Light Function

The service engine light (SEL) is connected directly to the vehicle’s electronic control unit, or ECU. This ECM serves a variety of different functions, including controlling the engine’s various systems. The car is fitted out with various sensors that send data to the ECM, from which it monitors the performance and health of your car. If the ECM (engine control module) detects that the car isn’t functioning according to factory standards it will turn the check-engine light on.

What Causes the Check Engine Light To Be On?

There are many possible causes of the check engine light being on. They include:

• Malfunctioning sensors or components.

• Problems with the fuel system.

• Issues with the ignition system.

• System malfunctions caused by poor maintenance.

• An issue with the air intake system.

• Defective exhaust valves.

• Fuel injection issues.

• Faulty wiring.
