The Technician may discover that P0128 - Thermostat Rationality DTC is present. This DTC is a two trip code and is matured if a significant difference exists between the PCM predicted and actual engine coolant temperature during engine warm-ups. The PCM calibration may improperly mature a P0128 DTC because the airflow across the coolant temperature sensor during colder ambient temperatures, 50° F (10° C) or below, causes the predicted coolant temperature to deviate from the actual coolant temperature.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10215810-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2013/MC-10215810-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10215810","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"},{"id":"manual-transmission","name":"Manual transmission","parent":"powertrain"},{"id":"transmission-control-module","name":"Transmission control module","parent":"powertrain"}],"codes":["P0128"],"topics":[],"vehicles":[{"make":"CHRYSLER","model":"PT CRUISER","year_from":2004,"year_to":2010,"match":"exact","vehicle_ids":["2004_chrysler_pt-cruiser","2005_chrysler_pt-cruiser","2006_chrysler_pt-cruiser","2007_chrysler_pt-cruiser","2008_chrysler_pt-cruiser","2009_chrysler_pt-cruiser","2010_chrysler_pt-cruiser"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
