This concern may be due to intermittent loss of signal from the reductant level sensor that is integrated into the reductant tank. If the applicable pinpoint test in the powertrain control/emission diagnostic (PC/ED) or workshop manual (WSM) directs replacement of the integrated reductant level sensor, do not attempt any repairs at this time and release the vehicle. Engineering is currently investigating this concern, monitor OASIS for updates regarding latest information and diagnostic direction.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10109007-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2017/MC-10109007-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10109007","components":[{"id":"engine","name":"Engine","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null},{"id":"fuel-system","name":"Fuel system","parent":null}],"codes":["P203B"],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2017,"year_to":2017,"match":"base","vehicle_ids":["2017_ford_f-250"]},{"make":"FORD","model":"F-650 SD","year_from":2016,"year_to":2017,"match":"base","vehicle_ids":["2016_ford_f-650","2017_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2016,"year_to":2017,"match":"base","vehicle_ids":["2016_ford_f-750","2017_ford_f-750"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
