Not yet, I don't have the tools. Can you describe where exactly you measured the sensor?

I don't remember the exact pin layout for the sensor. However, considering the symptoms and the mileage, it is very likely the camshaft encoder wheel is faulty, as on my Astra. I would recommend taking it to a workshop for proper sensor testing and diagnosis.

Thanks, I'll do that. The workshop confirmed the camshaft sensor was defective, likely due to the encoder wheel. The repair cost me 695€, but the van runs fine now.

I had a similar issue with my old Opel Astra, although it was a diesel. Rough starts, stalling, and the check engine light were all present. In my case, the encoder wheel on the camshaft was defective, messing with the ignition timing. Have you checked the camshaft sensor output with a multimeter or an oscilloscope?
