Reasons Why Your Check Engine Light Is On

There are a few different reasons why the check engine light comes on in your vehicle. These include low oil pressure, overheating, a leak in the coolant, and a failing mass airflow sensor. Here are some of the main reasons why your check engine light is on and what to do if it is on.

Low oil pressure

A low oil pressure check engine light can be caused by several things. One of these is a clogged oil strainer. This strainer is located in the crankcase and is attached to the oil pump. A clogged strainer is one of the most common reasons for low oil pressure. If you need to get wonderful suggestion about automobile engine light, you may go to motoradvices web site.

Typically, the light will come on whenever the oil pressure in your car falls below five or ten pounds per square inch (PSI) at idle. It can also come on due to a faulty oil pump or pickup tube, clogged oil filter, or internal oil leak. The light may also be accompanied by a knocking sound.

Overheating

The check engine light on your vehicle is a warning about overheating. The engine temperature warning light is linked to a sensor in your car’s engine computer. This sensor measures the temperature of your vehicle’s coolant. Coolant is a fluid that absorbs heat generated by combustion and releases it into the atmosphere. This system helps keep the engine operating at the correct temperature and ensures that your engine is working at maximum efficiency. If you notice that your engine is overheating, you should contact roadside assistance immediately.

Overheating is a serious problem for your engine, as it can cause permanent damage to the engine and other parts. To prevent this from happening, you should have your vehicle checked regularly. The main reason for overheating is a malfunctioning cooling system. A leak in the radiator, water pump, or hoses can all cause overheating.

Coolant leak

The check engine light can be caused by any number of issues. If you notice the light on your car, the first step is to find the source of the problem. A loose gas cap, for example, can cause the check engine light to turn on. If the gas cap is corroded, you will need to replace it. If you suspect a more serious problem, you may need to get your car checked by a mechanic.

Another common reason for the check engine light to come on is a problem with the engine sensor. This is because the ECU has lost a good read from the sensor. The problem may affect one or multiple sensors, making it difficult to identify the exact issue. While you can still drive with the engine light illuminated, it is best to pull over and get it checked out as soon as possible.

Mass airflow sensor failure

The mass airflow sensor, or MAF, is a critical component of your car’s engine. It measures how much air enters the engine and sends the information to the engine control module, which controls the fuel injectors. When your mass airflow sensor fails, the engine won’t get the correct amount of air to operate properly, which leads to performance issues.

Summary:

A failure of this sensor can cause a wide range of symptoms, from rough idling to misfiring and higher emissions. In many cases, a bad sensor will also result in problems starting the car and making it difficult to accelerate. Even worse, a bad mass airflow sensor will cause the engine to stall.
