What does the engine oil light sensor mean?

[StEthan]

Yellow engine oil light symbol sensor is a reminder that there is a fault with the oil pump or sensor, and the car needs to be inspected at a repair station when this issue occurs. The yellow engine oil light indicates insufficient oil pressure, which could be due to a lack of oil, a fault with the oil pump or sensor, or a blocked oil passage. Turn off the engine and check if the oil is severely deficient. If the oil level is sufficient, it might be due to a clogged oil pump or a faulty oil pressure sensor. Below is an introduction to the causes of the engine oil light turning on: 1. Insufficient oil volume: Normal oil consumption can cause the oil pump's output to decrease due to low oil volume, eventually leading to a drop in oil pressure and triggering the oil light alarm. 2. Engine temperature too high: Prolonged aggressive driving can put the engine under high-temperature load conditions. Even if the oil volume is sufficient, excessively high temperatures can thin the oil, causing it to leak through the gaps and resulting in a drop in oil pressure. 3. Damaged oil pump: If the components of the oil pump are worn or improperly assembled, leading to excessive gaps or abnormal operation, the oil pump may fail to deliver oil or deliver insufficient oil, causing the oil light to alarm.
