What is the problem with the U1313 fault code?

[DeJustin]

Fault code U1313 indicates an issue with the camshaft position sensor. Below is a detailed introduction: 1. Camshaft: The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. Although in a four-stroke engine, the camshaft's speed is half that of the crankshaft (in a two-stroke engine, the camshaft's speed is the same as the crankshaft), its speed is generally still very high, and it needs to withstand significant torque. Therefore, the design requirements for the camshaft in terms of strength and support are very high. 2. Sensor: A sensor is a detection device that can sense the measured information and convert it into electrical signals or other required forms of information output according to certain rules. This meets the requirements for information transmission, processing, storage, display, recording, and control.
