VelSatis Camshaft Sensor Issue

Sounds like the camshaft sensor for sure, especially with the check engine light and the stalling. It's not uncommon for those sensors to fail. Before you go replacing it, though, have you checked the wiring and the connector to the sensor itself? Sometimes a loose or corroded connection can cause similar symptoms. Also, have you had any work done on the engine recently? A misaligned crankshaft sensor can sometimes cause similar issues, and the ECU gets confused.

Good call on the wiring; I'll check that first thing in the morning. As for the crankshaft sensor, wouldn't that throw a different code? The OBD reader is specifically pointing to the CAMshaft sensor. I am assuming that is located near the top of the engine? And how would I test the sensor itself?

Yes, a crankshaft sensor issue usually throws a different code, but I've seen weird things happen! Since you're getting a specific camshaft sensor code, that's definitely the prime suspect. And yes, typically it's located near the top of the engine, near the camshaft pulley. As for testing the sensor, you'd need a multimeter to check the resistance and voltage, and honestly, unless you're comfortable with electrical testing, it might be best to take it to a workshop. They can properly diagnose it and confirm if it's just the sensor or if there's something else going on with the camshaft encoder wheel like you mentioned. Replacing that wheel isn't a simple job.

Huge thanks for the advice! I checked the wiring; all seems solid, so it probably IS the sensor. I chickened out on testing it myself, and took it to a local mechanic. They confirmed it was, indeed, the camshaft sensor causing the issue. They replaced the sensor and, unfortunately, they found that the encoder wheel was indeed defective, and was causing the sensor to report incorrect data. The whole repair ended up costing me 695€, but at least it's running smoothly again! Thanks again for pointing me in the right direction!
