Has a 206 have chain driven system?

No, the Peugeot 206 does not have a chain-driven system. It uses a timing belt to synchronize the movement of the crankshaft and camshaft. Timing belts are made of reinforced rubber and have teeth on the inside that mesh with gears on the crankshaft and camshaft. They are less expensive and easier to replace than timing chains, but they also have a shorter lifespan and need to be replaced more frequently.
