This bulletin applies to 2020-2021 Subaru Legacy and Outback vehicles equipped with a 2.4L DIT engine and 2019-2021 Ascent vehicles. New programming files are available to address DTC P1160 and customer concerns of extended cranking in cold temperatures. In rare cases, if the engine is switched off in extremely cold weather, the throttle plate may not return to the proper position. If this occurs, the next time the engine is started, the ECM detects the throttle plate as out of position and interprets the value as a failure, resulting in the extended cranking and the DTC. The throttle position sensing control has been optimized to avoid this issue.
