Default P1349 Code - VVT System Malfunction

Car runs just fine on the freeway, but is idling rough (sometimes dies) when stopped. Pulled a P1349 code. Mechanic says the OCR filter is clean, there is no sludge, and the solenoid is operating smoothly. He said that the intake VVT cam gear (which I assume from searching CL refers to the VVT controller assembly) is stuck in the up position and needs to be replaced. A few questions:

1) Is the VVT cam gear the VVT controller assembly?

2) How do you replace the VVT controller assembly?

3) Based on the symptoms I described, does the mechanics diagnosis seem correct?

Thanks in advanced.

You must replace the solenoid. Cleaning it doesnt work

The mechanic said the solenoid is fine. Are you suggesting that replacing the solenoid will fix my problem?

How does he know it's fine? Applying power to the solenoid doesnt necessary confirm that its good.

That's true. I was just going off what he was telling me.

Does anyone know another name for the VVT cam gear? Or even better, how to replace it? I looked at the factory diagrams and don't see it.

Solenoid failure is super common. I think I've heard of 1 cam gear ever failing. Hence why you can't find info on it

Solenoid is under 150 and is easy to replace.

The VVt cam gear is the camshaft. The solenoid controls the oil flow to the camshaft

Ok, so then the mechanic is saying that the camshaft needs replacing?

Something's not adding up because according to some of the other threads I found, the things that need replacing with a P1349 code are:

1.Valve timing
2.OCV
3. VVT controller assembly
4.ECM

As far as I can tell the camshaft is not on this list. Unless the VVT controller assembly is the camshaft/cam gear. Can someone clarify what the VVT controller assembly is?

Assuming the camshaft gears are fine. I would say the solenoid is defective. It is common

The controller is the cam gear. It's pretty straight forward to change as well.

If you can change a timing belt without thinking about it, then a cam gear is no problem.

Great thanks. Does anyone have the instructions on how to replace the VVT controller?
