Due to some customer’s driving patterns, they may not drive in the fashion needed to operate the VTEC (EGR/VVT) that only operates above 5,350 rpm to run the OBD monitoring. Therefore, the EGR/VVT OBD monitor group readiness status is not set to “Complete” when the customer presents their vehicle to a Smog Check station for inspection.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11000147-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-11000147-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11000147","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"ACURA","model":"ILX","year_from":2019,"year_to":2022,"match":"exact","vehicle_ids":["2019_acura_ilx","2020_acura_ilx","2021_acura_ilx","2022_acura_ilx"]},{"make":"ACURA","model":"MDX","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_acura_mdx","2020_acura_mdx"]},{"make":"ACURA","model":"MDX","year_from":2022,"year_to":2025,"match":"exact","vehicle_ids":["2022_acura_mdx","2023_acura_mdx","2024_acura_mdx","2025_acura_mdx"]},{"make":"ACURA","model":"MDX HYBRID","year_from":2019,"year_to":2020,"match":"base","vehicle_ids":["2019_acura_mdx","2020_acura_mdx"]},{"make":"ACURA","model":"RLX","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_acura_rlx","2020_acura_rlx"]},{"make":"ACURA","model":"RLX HYBRID","year_from":2019,"year_to":2020,"match":"base","vehicle_ids":["2019_acura_rlx","2020_acura_rlx"]},{"make":"ACURA","model":"TLX","year_from":2019,"year_to":2020,"match":"exact","vehicle_ids":["2019_acura_tlx","2020_acura_tlx"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
