Fusion Camshaft Sensor Issue
Summary of the thread
A 2005 Ford Fusion is experiencing poor starting, engine stalling, and an illuminated check engine light, suspected to be due to a defective camshaft sensor or encoder wheel. The error code P0340 indicates a camshaft position sensor circuit malfunction. It is suggested to also test the crankshaft sensor for a clearer diagnosis. Ultimately, a professional diagnosis is recommended to confirm the issue and proceed with necessary repairs.

Thanks for the quick reply! I haven't tested the crankshaft sensor yet, I'll add that to my list. I pulled a P0340 which points to the camshaft position sensor circuit malfunction. Does that match what you saw? Is there a specific way you'd recommend testing the crankshaft sensor? Any tips would be appreciated!

P0340 sounds exactly like what I had. I did some sensor testing myself, but honestly, it was a bit beyond my capabilities without the right equipment. In the end, I took it to a trusted workshop; they confirmed it was the camshaft sensor and the encoder wheel issue. I would suggest you to get a professional diagnosis.

Okay, thanks for confirming my suspicion and sharing your experience. I appreciate the advice about the workshop. I've booked it in and they've quoted 695€ for the camshaft sensor replacement and the encoder wheel repair. Hopefully, that'll sort it out. Thanks again for your help!

I had almost the exact same thing happen with my Fusion! The engine misfired, the check engine light was on, and it was stalling constantly. Have you tried testing the crankshaft sensor as well? It could be related, and might give you a clearer picture before you start replacing parts. What codes are you getting from the check engine light?
