The vehicle’s computer is responsible for making changes to the transmission gear ratios. This provides control over acceleration and speed, as well as efficient overall engine and fuel performance.
If the ratio of one of the gears of the vehicle is not within the expected parameters or it is not stored in the memory of the PCM (Powertrain Control Module), this code will be set.
