Corolla engine stalls camshaft sensor issue

I'm having a strange issue with my 2023 Toyota Corolla with gasoline engine. I've got 21109 km on the clock. Recently, it's been starting poorly, and the engine stalls at idle sometimes. Plus, the check engine light is on. I suspect it's the camshaft sensor, possibly a defective encoder wheel. Anyone seen this before?

I had similar symptoms with my Corolla. Did you check the camshaft position sensor? It could be faulty and messing with the ignition timing.

Yeah, I've considered the sensor. What were the specific codes you pulled when yours acted up? Trying to narrow it down.

I didn't pull the codes myself, but the workshop told me the camshaft sensor was the culprit. The encoder wheel on the camshaft was defective. They replaced the sensor and it fixed the stalling issue, but I would highly recommend getting to the workshop.

Thanks for the insight. Turns out you were spot on. Took it to the shop, and it was indeed the camshaft sensor and encoder wheel. Cost me 695€, but at least it's fixed now.
