Review of repair data supports that P206C is often the result of incorrect diesel exhaust fluid (DEF) concentration. Per Powertrain Control/Emissions Diagnosis (PC/ED) Pinpoint Test (PPT) RJ, a DEF concentration reading below 28% will set P206C and cause vehicle derate. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts. Low concentration of DEF is not a warrantable condition.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10205446-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10205446-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10205446"},{"nhtsa_id":10186621,"type":"service_bulletin","type_name":"Service bulletin","date_added":"2021-02-04","date":"2021-01-21","document_id":"SSM 49483","mfr_campaign":null,"component":"POWER TRAIN","summary":"Some 2017-2021 F-Super Duty and 2016-2021 F650-750 with 6.7L diesel engines, 2015-2019 Transit with 3.2L diesel engines and 2018-2021 F-150 with 3.0L diesel engines may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM).
