A check engine light may turn on for misfire caused by temporary over rich fuel injection. This concern only occurs with the condition that the coolant temperature at the time of engine start is about 32 F (0 C) or less. This is caused by improper control software of the PCM. To eliminate this concern, the control software of the PCM has been modified.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10226822-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10226822-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10226822","components":[{"id":"engine","name":"Engine","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-50","year_from":2023,"year_to":2023,"match":"exact","vehicle_ids":["2023_mazda_cx-50"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
