1. Check and replace if necessary the Camshaft Position Actuator B Bank 2. Bank 2 is the left side cylinder block bank, (driver's side for LHD vehicles). Also see if the variable camshaft mechanism movement is all right, and nothing can block it. The codes 16408 and 16684 must be eliminated definitely!
2. Then test the engine. If the code 16689 = Cylinder 5 - misfire detected, still occurs, check the spark plug, ignition coil and injector. Replace bad piece(s). The code 16689 must be eliminated definitely!
3. The codes 16805 = Warm Up Catalyst Bank-1, Efficiency Below Threshold, and 16815 = Warm Up Catalyst Bank-2, Efficiency Below Threshold, are caused by the misfires sending unburned fuel into the exhaust, and will be erased from Engine Control Module memory.
Test the car and send me back if everything is OK, or if any DTC code still remains.
Good Luck!
Hi!!
I believe you're right about the 4 codes below are due to the rich mixture or unburnt fuel.
16684 =Random/Multiple Cylinder Misfire Detected
16689 = Cylinder 5, Misfire Detected
16805 =Warm Up Catalyst Bank-1, Efficiency Below Threshold
16815 = Warm Up Catalyst Bank-2, Efficiency Below Threshold
The code 16408 =Camshaft Position Actuator B Bank 2, Timing Over-Advanced. Could be due to the timing being set wrong or the CMP Sensor being defective.
Click on the following link for detail instructions to test the Camshaft Position Sensor. Note that there are two sensors, one for each bank. Bank #1 is on the side of the vehicle where the #1 cylinder is. Bank #2 is the other side.

Good Luck! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Observe the scan tool CMP Desired, Actual, and Angle Variance parameters before a DTC sets. This may help to isolate whether a condition is specific to one camshaft, one bank, or caused by a condition with the primary crankshaft timing.

I'm sorry but when dealing with these problems your best bet is to take your vehicle to a qualified repair shop , I have never see a DIY'ER correct the problem with these , an in the end always end up taking it to the dealer .

I think your sensors are pattern parts and the readings /resistances are not the same as the original parts ,try some bosch units is my first suggestion ,

This 3.0 engine does not have the timing chains and the camshaft actuator like the previous V6's so the advice by the first "expert"doesn't apply.
