Entry-level technicians typically perform all the following tasks EXCEPT:

The task of using a scan tool to pinpoint engine performance problems is typically more advanced than what entry-level technicians are usually trained to handle. While entry-level technicians may have basic training on the principles of engine operation and performance, the ability to interpret data from a scan tool requires a deeper understanding of engine diagnostics, potential issues, and repair strategies that typically come with more experience and specialized training.

In contrast, changing engine oil, performing a general visual inspection, and checking all fluid levels are fundamental maintenance tasks that entry-level technicians are expected to know and carry out. These tasks require basic mechanical skills and a foundational knowledge of vehicle maintenance rather than the advanced diagnostic skills needed for using a scan tool effectively. This distinction highlights the increasing complexity and expertise involved in diagnosing engine performance issues compared to routine maintenance tasks.
