The cost to diagnose the P107A code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
On the Valvetronic VVT (Variable Valve Lift Control), the variable valve gear reduces fuel consumption by adjusting the stroke of the intake valves. An electric motor is used to drive a worm gear that moves the eccentric shaft. The eccentric shaft uses intermediate levers that change the effect of the camshaft on the rocker arms.
Electrical overload protection. The engine management monitors the Variable Valve Timing (VVT) motor's current draw. If the monitored current draw exceeds a defined threshold for several seconds the VVT system is deactivated (VVT emergency operation mode), and the engine reverts to throttled operation.
