What action should be taken if the oil pressure gauge does not indicate normal pressure after starting the engine?

The correct action when the oil pressure gauge does not indicate normal pressure after starting the engine is to turn off the engine immediately. This is crucial because low oil pressure can signal a serious problem, such as an oil leak or a malfunctioning oil pump, and continuing to run the engine under these conditions can lead to severe engine damage.

Additionally, checking the oil level is a key follow-up action, as low levels might be the reason for the low pressure—insufficient oil can’t circulate properly, leading to the pressure drop. Inspecting all hoses for leaks is also a necessary precaution, as any leaks could further exacerbate the oil pressure issue.

By choosing the comprehensive approach of turning off the engine immediately and considering the checks of oil level and hose inspections, you are effectively covering all critical safety measures that should be taken in the event of abnormal oil pressure readings. This multifaceted response helps ensure the vehicle’s engine can be assessed accurately and protected from potential harm.
