Hi Carlos
I think what your caravan has is that they did not calibrate the distance of the CKP sensor with the toothpray, but it is easy to put a cardboard type presentation card between the hoop and the CKP sensor and tighten the sensor and remove the cardboard or card, and ready is like 1mm away between one and the other.
I hope and solve your problem and if you reviewed everything that the CKP is defective.
