The Engine Control Module (ECM) may not properly handle diagnostic information for the exhaust Particulate Matter (PM) sensor. This can prevent the PM sensor signal from being used to diagnose the functionality of other components. Additionally, if a PM sensor fault occurs, it may not result in setting a Diagnostic Trouble Code (DTC) or Malfunction Indicator Lamp (Check Engine Light) illumination. Dealers are to reprogram the ECM.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244215-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10244215-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10244215","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"CHEVROLET","model":"EXPRESS","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_chevrolet_express"]},{"make":"CHEVROLET","model":"EXPRESS CUTAWAY VAN","year_from":2019,"year_to":2019,"match":"base","vehicle_ids":["2019_chevrolet_express"]},{"make":"GMC","model":"SAVANA","year_from":2019,"year_to":2019,"match":"exact","vehicle_ids":["2019_gmc_savana"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
