P0015 code, what does it mean, how do you fix it

runnymede

Yesterday, my 2013 Avalon XLE, with almost 95K miles, the dashboard lite up. Ran the codes and got the P0015 Code. P0015 - "B" Camshaft Position - Timing Over-Retarded (Bank 1)

All the other lights reset after restarting the engine, but the Check Engine Light is still on.

What does this mean and how hard is it to repair / Fix

Thanks in advance.

It means exactly what the code description says. The exhaust camshaft timing is retarded. The camshaft timing is controlled by a solenoid that directs oil to the camshaft actuator to advance or retard the camshaft as required by the current engine operating conditions. When that code sets there is a failure in the system that allows the timing to go retarded and the computer can't command the camshaft to move to the desired position. Some of these are very easy to solve such as a solenoid that has failed or is sticking. Some can be much more involved if the engine is sludged up or the timing chain is failing.
