Which technician is correct regarding troubleshooting an oil pressure warning light?

In this scenario, Technician B is correct regarding troubleshooting an oil pressure warning light. When faced with an oil pressure warning light, the primary step in troubleshooting is to check the oil level and condition; low oil levels or contaminated oil can often trigger this light.

Additionally, after confirming sufficient oil levels, a technician would typically proceed to investigate the oil pressure sending unit and related circuits, as a faulty sending unit can also result in a misleading warning light. This systematic approach is critical, as it addresses the potential causes in a logical order, ensuring that the root of the issue is identified and resolved effectively.

It is essential to understand that troubleshooting involves not only checking the warning light itself but also considering the entire lubrication system's performance. Gathering accurate data about oil levels, pressure readings, and engine condition is necessary before concluding on the warning light's significance.
