I have a 2004 Mazda 6 and its making a whining noise when running and idles rough. Code says its a cam sensor. Would that cause a whining noise from under the hood. Heres where you can find a you tube video www.youtube.com/watch?v=I7CeVHVeJZk

Noises tough even with the video. For now IDK but will show it as a link......... https://www.youtube.com/watch?v=I7CeVHVeJZk To me that noise is more like an electric motor failing. Why the idle not so sure so let other chime in. Code - please post the # but it has one and may have nothing to do with the noise, T

Thank you so much I dont have the code was at Advance this morning. I just find it hard to believe that sensor is causing that whining noise.

I may not be around too much for some of the day but will suggest some things you could try if you can. To me the noise could be travelling away from where you might think the source is. It's clear enough you could probably hear it with a mechanic's stethoscope or just a listening rod to your ear. Careful doing that around moving parts. Could rule out any belt driven item by taking belt off and just run for a quick while to see if noise goes away and if so spin the items on that belt by hand for feel. To me that noise sounded almost exactly like a small electric motor like a washer pump - power door lock size motor type something gone bad or disconnected and would have to be to spin that much but not near the engine at all. The ticking sounded like normal noise to me from injectors. That's about it until you can peg it down more precisely. I doubt crank sensor makes that noise even if there's a problem with that circuit? T

First things first, I would get that cam sensor code resolved. That noise is tough. Would need to be there to hear what area it is coming from. Smog pump,alternator, cooling fan, anything that moves really could make that noise, including engine components. ____________________________________________________ Willing to help, willing to learn...

Sounds like a vacuum leak. If you snap the throttle, does the noise go away? Take a spray bottle with water and spray around the intake manifold. If you hit the leak, it will make a sucking noise and change pitch. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

It was a huge vacuum leak between plastic intake manifold and motor. Manifold had cracked somehow
