This may be due to a stuck internal component of the variable cam timing (VCT) unit. To correct the condition, replace all 4 of the VCT units following Workshop Manual (WSM), Section 303-01. For claiming, use causal part 6C525 and applicable labor operations in Section 6 of the Service Labor Time Standards (SLTS) Manual. If labor times are not available, claim M-time.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10254122-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10254122-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10254122","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco","2024_ford_bronco"]},{"make":"FORD","model":"F-150","year_from":2020,"year_to":2024,"match":"exact","vehicle_ids":["2020_ford_f-150","2021_ford_f-150","2022_ford_f-150","2023_ford_f-150","2024_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
