After parking at temperatures below freezing, the throttle valve may be frozen at the stand-by position, resulting in the symptom. To prevent this concern, the control logic of the PCM has been modified to avoid frozen the throttle valve (by moving the valve at a certain time after the ignition has been turned off). NOTE: With this modification, the main relay may stay on up to 90 minutes after the ignition switch is turned off. \"BATTERY INSPECTION\" in the Workshop Manual will be modified to properly check the battery parasitic draw after this modification.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10129572-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10129572-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10129572","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P0638","P2112"],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-9","year_from":2016,"year_to":2018,"match":"exact","vehicle_ids":["2016_mazda_cx-9","2017_mazda_cx-9","2018_mazda_cx-9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
