Some 2010-2015 Toyota Prius, 2012-2015 Prius PHV and 2012-2016 Prius V vehicles equipped with a 2ZR-FXE engine may exhibit a MIL on with DTC P2111 (throttle actuator control system) and P0A0F (engine failed to start) present when ambient temperatures are below 23 degrees Fahrenheit, following the cold soak.
