How can i repair P0015 B camshaft postion over retarted bank 1 on a toyota corolla

Answer 1

You could start by changing the engine oil level. Dirty oil could cause that problem. Also make sure you use the oil weight recommended by the factory. Try using either 0W-20 or 5W-20. If the problem persist you may have to replaced the the variable valve timing.
