P0015 = "B" Camshaft Position -Timing Over-Retarded (Bank 1)

What causes the P0015 code?
The variable camshaft timing (VCT) oil control valve (OCV) is stuck in the open position.

The camshaft phaser is stuck in the retarded position due to damage or clogged oil passages.

Oil flow problems to the VCT piston and phaser from incorrect oil viscosity.

The OCV has an open circuit or the ECM has an open circuit.

What repairs can fix the P0015 code?
Resetting the fault codes and performing a road test
Replacing camshaft phasers on both camshaft banks
Repairing the wiring or connection to the camshaft OCV
Replacing the camshaft OCV for bank 1 exhaust camshaft
Replacing timing chain and guides
