VW Code 16647
16647 Description And Summary : |
|---|
Staring in engine linear oxygen sensor exhaust bank 3 / common ground wire, short to ground the system depends on oil pressure to switch between cam profiles manifold absolute pressure / mass air flow - throttle position correlation at higher load or change engine coolant temperature sensor 2 (g83), circuit range / performance is the final reason of the code. |
16647 Possible Causes:
16647 vw fault code may be caused by one or more of the following:
