This is likely due to the driver door not being fully closed and locked during the on-demand self-test. A false P166B DTC can set if the driver door is not fully closed or if it is unlocked during the self-test. If P166B is still present with the driver door fully closed and locked during the on-demand self-test, continue with normal diagnostics in Workshop Manual (WSM), Section 307-05.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10209220-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10209220-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10209220","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["P166B"],"topics":[],"vehicles":[{"make":"FORD","model":"GT","year_from":2017,"year_to":2022,"match":"exact","vehicle_ids":["2017_ford_gt","2018_ford_gt","2019_ford_gt","2020_ford_gt","2021_ford_gt","2022_ford_gt"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
