There is the possibility that moisture can get into the ground splice connections in the wire harness for the engine. As a result, ground splice connections can become corroded over the service life of the vehicles. This can cause signal faults in the oil pressure, oil level and oil temperature sensors, and therefore cause the Check Engine warning light to be activated.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10109312-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2012/MC-10109312-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10109312","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"wiring","name":"Wiring and fuses","parent":"electrical"}],"codes":[],"topics":[],"vehicles":[{"make":"PORSCHE","model":"PANAMERA S","year_from":2010,"year_to":2011,"match":"base","vehicle_ids":["2010_porsche_panamera","2011_porsche_panamera"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
