Current circuit diagram for the crankshaft sensor KWS at CNG different?

Hello together, can anyone tell me if the KWS is running over the controller of Prins? Or if the signal is picked up on the way? A circuit diagram of KWS at the 2.5T with CNG would be great. Background is this: Volvo had changed the sensor in January, because ECM-P033500 occurred permanently and I still have problems with the ride (complete dropouts and start problems, both in cold or “half warm” engine). After a month this error occurs again very violently. I would like to look very much for cable breakage and mass contact errors. I don’t want to think about a mistake in the control unit at the moment. I have found a company now, which specializes in such troubleshooting. Even Volvo would hate to get there.
