This code is set if the value of input shaft speed is not equal to the value of the output shaft, when multiplied by the second gear ratio, while the transaxle is engaged in second gear. This malfunction is mainly caused by mechanical troubles such as control valve sticking or solenoid valve malfunctioning rather than an electrical issue.
I would suggest first checking the transmission oil level and quality. The fluid should be red/light brown and not smell burned.
