What Causes the Check Engine Light to Come On?

The check engine light is a generic term that refers to the Malfunction Indicator Lamp (MIL) on your dashboard. It’s designed to alert you to potential problems with your vehicle’s engine, transmission, or other systems. The light can come on due to a wide range of issues, including:

  • Faulty oxygen sensor

Can an Oil Change Cause the Check Engine Light to Come On?

So, can an oil change cause the check engine light to come on? The answer is yes, but it’s not always the case. Here are some scenarios where an oil change might trigger the check engine light:

Scenario 1: Incorrect Oil Type or Quantity

If you use the wrong type of oil or don’t use enough oil, it can cause the check engine light to come on. This is because the engine’s computer system is designed to monitor the oil level and type. If it detects an issue, it will trigger the check engine light to alert you to the problem.

Scenario 2: Oil Filter Issues

A faulty or clogged oil filter can also cause the check engine light to come on. This is because the filter is designed to capture contaminants and debris in the oil. If it’s not functioning properly, it can cause the engine to run rich or lean, triggering the check engine light. (See Also: Why Would Oil Leak from My Car? Common Causes Revealed)
