Hi, driving a Nissan k12 bj. 05. 2004 with 65ps. A month ago the motor bikes started. Error code camshaft Positinssensor P040 was that I think. That also the friendly immediately changed for knap 120€. Two weeks then stopped after then in the morning and again the motor lamp is on. I made again to the friendly. Date he wants to measure through any times, check wiring, chain on length according to marking, etc. Supposedly lauft that is on a hooked chain!! So here in the forum in the SUF I can read, that the affected car usually went out during the ride, bad went, the engine was restless. With me is not of that. The car lauft Perfect, never went out, always goes great. Mornings event. until loud, but that gives itself after a few driven kilometers. It also write which the crankshaft sensor could be defective, but it would be quite noticeable and with me is nothing of the car I had bought before the car, but had had to have bought it before the same thing.
