Summary
Some 2017-2022 F-Super Duty and 2016-2022 F-650/F-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). 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.

Summary
Some 2017-2018 F-Super Duty/2016-2018 F650-750 with 6.7L diesel engines and 2015-2018 Transit with 3.2L diesel engines may exhibit a MIL on with diagnostic trouble code (DTC) P206C in the powertrain control module (PCM). This may be due to incorrect diesel exhaust fluid (DEF) concentration. Prior to performing Powertrain Control/Emissions Diagnosis (PC/ED) pinpoint test RJ, confirm DEF concentration using IDS to monitor REDUCT_CONC_MES. This PID reading may fluctuate between 31% and 34% indicating DEF concentration is correct. A concentration reading below 28% will set P206C and cause vehicle derate. This reading may also be checked using Central Tools Refractometer (CEN3R201) which should indicate a similar percentage as the PID. Low concentration of DEF is not a warrantable condition. If low concentration is suspected, drain fluid and replace with known good DEF before replacing any parts.

Some 2017 F-Super Duty, 2016-2017 F650-750 equipped with 6.7L diesel engines and 2015-2017 Transit equipped with 3.2L diesel engines may exhibit a MIL on with diagnostic trouble code (DTC) P206C stored in powertrain control module(PCM). This may be due to incorrect diesel exhaust fluid (DEF) concentration. Prior to performing Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test RJ, ensure DEF concentration is checked using Central Tools Refractometer tool number CEN3R201 and if DEF contamination is suspected use the Rotunda Hydrocarbon Test Kit tool number 328-480508.
