This may be due to the engine coolant temperature (ECT) sensor or ECT sensor wiring harness. For 2.3L vehicles, replace the ECT sensor and pigtail wiring connector (GU2Z-14S411-KA). For 3.0L vehicles, replace the ECT and knock sensor. To aid with the engineering investigation, do not disconnect the wiring connector from the ECT sensor during disassembly. Leave the connector on the sensor in case parts are called back for analysis.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10184642-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10184642-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10184642","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":["P0116","P0117","P0118","P0119","P0128","P0217","P0330","P1026","P1299","P130D"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPLORER","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2020,"year_to":2020,"match":"exact","vehicle_ids":["2020_lincoln_aviator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
