This may also be due to ice forming in the air intake while operating in temperatures below -22°F (-30°C). Diagnostic trouble code (DTC) P1548 may be present in the powertrain control module (PCM). To supplement heavy snow environment pre-filter service kit (service part LC3Z-9K635-AA), a front grill cover (service part NC3Z-19A413-A) is now available for service but is not a warrantable item. It is recommended that the front grill cover be removed at temperatures greater than 10°F (-12°C) and reinstall in subsequent winter seasons in order to maintain optimal vehicle performance.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236585-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236585-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10236585","components":[{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["P1548"],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-250","2021_ford_f-250","2022_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-350","2021_ford_f-350","2022_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-450","2021_ford_f-450","2022_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-550","2021_ford_f-550","2022_ford_f-550"]},{"make":"FORD","model":"F-600 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-600","2021_ford_f-600","2022_ford_f-600"]},{"make":"FORD","model":"F-650 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-650","2021_ford_f-650","2022_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-750","2021_ford_f-750","2022_ford_f-750"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
