The changes are noted in Red text. 01-003/26 01/30/26 Some vehicles may exhibit a check engine light ON with DTC P20F8:00 stored. P20F8:00 - Swirl control circuit range/performance problem. In these cases, increasing temperature levels of the Swirl Control Valve (SCV) motor due to excessive actuation leads to duty limitation, causing poor opening􀀀angle response and resulting in a stuck judgment.

Refer to MDARS ECU Reprogramming Procedure.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032001-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11032001-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11032001","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["P20F8"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-30","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_mazda_cx-30","2024_mazda_cx-30","2025_mazda_cx-30"]},{"make":"MAZDA","model":"CX-5","year_from":2024,"year_to":2025,"match":"exact","vehicle_ids":["2024_mazda_cx-5","2025_mazda_cx-5"]},{"make":"MAZDA","model":"CX-50","year_from":2024,"year_to":2025,"match":"exact","vehicle_ids":["2024_mazda_cx-50","2025_mazda_cx-50"]},{"make":"MAZDA","model":"MAZDA3","year_from":2023,"year_to":2025,"match":"exact","vehicle_ids":["2023_mazda_mazda3","2024_mazda_mazda3","2025_mazda_mazda3"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
