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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10120378-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10120378-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10120378","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"labels-manuals","name":"Labels and manuals","parent":null}],"codes":["P0015","P0524"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-3","year_from":2016,"year_to":2018,"match":"exact","vehicle_ids":["2016_mazda_cx-3","2017_mazda_cx-3","2018_mazda_cx-3"]},{"make":"MAZDA","model":"CX-5","year_from":2013,"year_to":2016,"match":"exact","vehicle_ids":["2013_mazda_cx-5","2014_mazda_cx-5","2015_mazda_cx-5","2016_mazda_cx-5"]},{"make":"MAZDA","model":"MAZDA3","year_from":2012,"year_to":2018,"match":"exact","vehicle_ids":["2012_mazda_mazda3","2013_mazda_mazda3","2014_mazda_mazda3","2015_mazda_mazda3","2016_mazda_mazda3","2017_mazda_mazda3","2018_mazda_mazda3"]},{"make":"MAZDA","model":"MAZDA6","year_from":2014,"year_to":2018,"match":"exact","vehicle_ids":["2014_mazda_mazda6","2015_mazda_mazda6","2016_mazda_mazda6","2017_mazda_mazda6","2018_mazda_mazda6"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
