There was a study conducted in 2019 to test the check engine light and its efficiency. Consequently, for drivers whose check engine light is on, this study showed that the light is incredibly accurate and able to detect problems that are otherwise invisible. RB Auto Service can determine why the check engine light has come on on your European automobile’s dashboard. Here are common reasons for the warning.
Faulty Catalytic Converter
The catalytic converter is part of the exhaust system. This part processes the carbon monoxide found in your vehicle’s exhaust to convert it to carbon dioxide. Eventually, the converter can get clogged. A faulty catalytic converter will turn on your check engine light and overheat the engine.
Faulty Electrical System
You may also receive a check engine warning if you have a problem with your European automobile’s electrical system. This can include issues with the engine control module and system sensors. In fact, a malfunctioning engine control module will turn on the check engine light.
Fuel System/Balance Problems
If there is an imbalance between the fuel and air in your combustion chamber, your check engine light will come on and you will notice acceleration and engine performance issues. You may also end up with the check engine warning if your fuel Is not screwed on tightly.
Malfunctioning MAF Sensor
The MAF sensor is the mass airflow sensor. If you take good care of your European automobile, you may never have any problems with this sensor. If it does malfunction, however, the check engine light will turn on. You may also notice a reduction in your engine performance and fuel economy.
Malfunctioning O2 Sensor
The O2 sensor is the oxygen sensor. This part lasts, on average, just under 100,000 miles. You will find the oxygen sensor in the tailpipe at the start of it. This sensor measures the levels of oxygen in your vehicle’s exhaust and sends the numbers to the engine control module.
Transmission Problems
You may also end up with the check engine light warning if your transmission is struggling. Other signs of transmission problems include grinding or squealing sounds when your vehicle shifts gears, slipping out of gear, and refusing to go into gear.
Worn Spark Plugs
Finally, worn spark plugs can also cause the check engine light to turn on. Today’s spark plugs can last as long as 100,000 miles before they need to be changed. If you are overdue for an engine tune-up, including a plug change, you may end up with the check engine warning.
