Understanding the Engine Light
The engine light, also known as the check engine light, is a critical component of your vehicle’s onboard diagnostics system. It’s designed to alert you to potential problems with your car’s engine, transmission, or other systems. When the light comes on, it can be a sign of a minor issue, such as a loose gas cap, or a more serious problem, such as a faulty oxygen sensor.
There are two types of engine lights: the “check engine” light and the “service engine soon” light. The “check engine” light is usually yellow or amber and indicates a problem that needs to be addressed. The “service engine soon” light is usually red and indicates that a routine maintenance task, such as an oil change, is due.
Can an Oil Change Make the Engine Light Come On?
So, can an oil change make the engine light come on? The answer is yes, but it’s not always a straightforward issue. Here are some possible reasons why an oil change might trigger the engine light:
- A faulty oil change procedure: If the oil change is not done correctly, it can cause the engine light to come on. This could be due to incorrect oil levels, improper oil filter installation, or failure to reset the oil change indicator.
- Old or dirty oil: If the oil is old or dirty, it can cause the engine light to come on. This is because the oil is not doing its job properly, which can lead to engine problems.
- Oil change interval: If the oil change interval is not followed, it can cause the engine light to come on. This is because the oil is not being changed frequently enough, which can lead to engine problems.
- OBD-II system: The OBD-II system is designed to monitor the engine and alert the driver to potential problems. If the oil change is not done correctly, it can trigger the OBD-II system to alert the driver to a problem.
