Engine Diagnostics: Engine Light

The engine light is a warning light that comes on when there is a problem with the engine. It can be a sign of a major problem, such as a fire, or it can be a sign of a minor problem, such as a loose wire. In diagnosing the problem, the technician will often use a diagnostic tool, such as an onboard computer, to determine what the problem is.

So if your car isn’t running as it should, get it diagnosed by a professional auto repair near you.

Engine’s Oil

One of the most important things that an auto technician does is to check the engine’s oil by using a dipstick to measure the oil level, and then they check the oil’s condition. If the oil is low, they may add oil to the engine. If the oil is dirty, they may change the oil.

The auto technician is also checking for any leaks in the engine.

Oxygen Sensor

Car Diagnostic Test

An oxygen sensor is a small electronic device that helps monitor the levels of oxygen in a vehicle’s exhaust system. It is located in the exhaust system, before the catalytic converter. The oxygen sensor monitors the exhaust gas coming from the engine and sends a signal to the vehicle’s computer.

The computer uses this signal to adjust the air/fuel mixture. It is one of the most important components in a vehicle’s emissions control system. After the emission testing is completed, the auto technician will check the engine’s health and make sure it is running properly.

Loose Gas Cap

The auto technician is checking the loose gas cap to ensure that the engine is receiving the proper amount of fuel. The fuel system is responsible for delivering the correct amount of fuel to the engine, and the gas cap is one of the components that help to regulate this flow. If the gas cap is not functioning properly, it can cause the engine to receive too much or too little fuel, which can lead to engine performance problems.

Spark Plugs And Cables

Car Maintenance

The auto technician is checking the spark plugs and cables to ensure that they are in good working condition. They are responsible for delivering the spark that ignites the fuel and air mixture in the cylinders. The spark plugs and cables can tell the technician a lot about the health of the engine and can help diagnose any problems that may be present.

If the plugs and cables are not in good condition, they will need to be replaced
