Hello, I have a 2016 f55 s version and recently tune a JB4 tuner stage 1, when I installed it I didn’t watch the tutorial and unplayable the mass air flow sensor and plug with one of the by pass, I realized it and installed correctly afterward, but now I have a drivetrain malfunction with error code 120408 (reduced power mode) with a 108A06, on the JB4 app it shows the IAT sensor is 0 all the time, right now the fuel economy decreased and the lack of power. Is it possible to just change the sensor by my own?(idk what sensor tho) Thank you
