- [10185906](https://open.wenmarpro.com/bulletins/10185906), 2021-01-28: Some vehicles may experience a rough idle with the check engine light on and DTC P0015 / P0524 stored in memory. P0015:00 \- Exhaust CMP timing over\-retarded, P0524:00 \- Engine oil pressure too low. This is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump pressure relief valve or oil control valve \(OCV\). The temporary entry of the foreign object triggers a check engine light on, but rough idle will not be produced until a later time.
