P1384 Variable valve timing (VVT) solenoid malfunction "A" bank
The cause for this code condition are VVT solenoid failure, oil flow fault to VVT, VVT camshaft mechanical fault, ECM fault, with the tapping noise, this is definetly a oil supply problem, the oil pressure should be check, the solenoid if it fails will cause rough idle but no tapping engine noise, Unless the idle is rough that the lifter collapsed. Chang the motor oil and filter use a heavier oil such as 10w 40 weight. If the tapping noise goes away replace the VVT solenoid.
