Codes P0390, P0365, P0345, P0341, andP0340, Camshaft position sensor?

Hi,

The codes indicate a problem with each of the four camshaft position sensors (see pic below). Did these all set at once? How is the engine presently running? Is the engine oil clean and full?

Also, has anything ever been done with the timing chains? This vehicle has three of them. There is a primary and two secondary chains. If these all set at the same time, there is a chance the primary is off.

Pic 2 shows the locations of the 4 sensors.

Let me know.

See pics below.

It will not start, and i am about to lose my job so I really need to fix it. It is do for an oil change but it's -30 below so not today. So, what should I try first?

If the starter is engaging and turning the engine, see if it starts with starter fluid. If it does and then stalls, we know it's a fuel issue. If there is no change, check to see if there is spark to the plugs.

Here is a link that explains how to check:

Also, if you could record the engine cranking and upload it for me to hear, that would be helpful. Since we have codes for all cam sensors, I'm questioning if there is an issue with engine timing. I should be able to tell by listening to it crank.

Let me know.
