P0016 -CRANKSHAFT/CAMSHAFT TIMING MISALIGNMENT - BANK 1 SENSOR 1
Set Condition:
The Powertrain Control Module (PCM) detects that the deviation between the camshaft position and the crankshaft position has exceeded the maximum acceptable value.
Could be crankshaft or camshaft position sensors. Typically they're both replaced at the same time just to make sure.
B105D could be the recirculation door actuator or the door stops. It's more common for the actuator to fail but sometimes it's the linkage rod or door cam. Difficult to tell without observing it in operation.
