Trafic Camshaft Sensor Encoder Wheel Issue

My 2007 Renault Trafic diesel has starting issues, stalls at idle, and the check engine light is on at 90939 km. I suspect a defective camshaft sensor, maybe from a faulty encoder wheel. Thoughts?

I had similar symptoms with my Trafic: difficult starts and stalling. Have you checked the ignition timing and sensor output? Sounds like sensor failure, but test it before replacing.

Thanks. Could you tell me more about your sensor experience? Did you also think it was the encoder wheel on the camshafts?

Yes, the encoder wheel was the root cause in my case, which lead to a camshaft sensor defective. Given the symptoms and mileage, if you can't test the sensor yourself, take it to a workshop for diagnosis and repair.

Thanks! I had it inspected, and the diagnosis confirmed the camshaft sensor issue from the encoder wheel. Repair cost was 695€.
