Code PO731 refers to an issue with the transmission, specifically indicating that the "Gear Ratio Incorrect" is detected in first gear. To fix this, start by checking the Transmission Fluid level and quality, as low or dirty fluid can affect shifting. Then, inspect the transmission components, including the input and output sensors, for faults or damage. If necessary, perform a transmission recalibration or consult a professional mechanic for further diagnosis and repairs.
