- Low oil level: If the oil level is too low, the oil pump will not be able to circulate enough oil to the engine, leading to low oil pressure.
- Oil leak: A leak in the oil system can also cause the oil level to drop and lead to low oil pressure.
- Faulty oil pump: The oil pump is responsible for circulating oil throughout the engine. If the oil pump is faulty, it may not be able to generate enough pressure to circulate the oil properly.
- Worn engine bearings: Worn engine bearings can also cause low oil pressure. When the bearings wear out, they can create a gap between the bearing and the crankshaft, allowing oil to leak out and reducing oil pressure.
- Clogged oil filter: A clogged oil filter can restrict the flow of oil to the engine, leading to low oil pressure.
- Oil viscosity too high: If the oil viscosity is too high, it can make it difficult for the oil pump to circulate the oil effectively, leading to low oil pressure.
If you see the "stop engine low oil pressure" code on your Cadillac Sedan Deville, it's important to take action immediately. Low oil pressure can cause serious engine damage, so it's important to identify and address the cause of the problem as soon as possible.
