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.
