Learn More About Engine Oil Light Diagnosis Cost
The engine oil light can illuminate due to low oil pressure, a defective pressure sender or a problem with the wiring for the oil warning light. Diagnosing this problem will require checking the oil level, oil quality and oil pressure. If the oil pressure is OK, then a diagnosis of the sender, wiring and gauge will be performed.
If the oil light is on, it's best to avoid driving so as to avoid possible engine damage. Check the oil level and add oil if needed. Then have a shop diagnose the issue to avoid any future problems.
If the incorrect type of oil is used, the oil pressure can drop too low and cause the oil light to come on.
Some vehicles can have internal oil system seals that leak, which will cause low oil pressure. Failure to identify these leaks can lead to the replacement of un-needed parts.
