What is the fault code for incorrect timing?

[DelBlakely]

Incorrect timing will not trigger a fault code. If the car's timing is incorrect, it can lead to insufficient power, engine shaking at idle, and in severe cases, cause the engine's valves and pistons to collide, resulting in engine damage. The timing belt connects the camshaft and crankshaft, controlling the opening and closing of valves and the rotation of the crankshaft and the up-and-down movement of pistons. Therefore, if the timing belt is misaligned, it will cause the valves to open and close at the wrong time, and the pistons to move up and down incorrectly. Minor issues may result in insufficient power and vehicle shaking, while severe cases can cause the valves and pistons to collide, leading to damage. At this point, the engine will stop working and require repair. Ignition timing in gasoline engines is crucial for fuel combustion. Correct ignition timing not only ensures complete fuel combustion and maximizes thermal efficiency, guaranteeing normal engine power output and achieving maximum effective power, but also effectively prevents a series of faults caused by engine knocking, such as piston burning, broken rings, cylinder scoring, and power loss.
