DTC code P1351 typically indicates an issue with the variable valve timing (VVT) system, often related to the VVT sensor or the timing control circuit. To fix this code, start by inspecting the VVT sensor and its wiring for damage or loose connections. If the sensor appears functional, check the oil level and quality, as low or dirty oil can affect VVT operation. If necessary, replace the faulty sensor or repair any wiring issues, and clear the code using an OBD-II scanner to see if it returns.
