Just to further clarify this thread:
Code P0340 is the camshaft postion sensor on the passenger side (bank one). It is a straight sensor with a green connector going to it on the back of the motor. It is real close to the transmission dip stick.
Code P0345 is the camshft postion sensor on the drivers side (bank two). The sensor is angled, also with a green connector plug. It is easy to get to if you remove the throttle body and the hose under the throttle body. The plug is hard to get off. Squeeze the tab with a pair of needle nose and pull like hell.
Both of these sensors are held on with a single 10mm bolt.
The symptoms are the same, VDC, slip and SES light all on, long crank to start.

On a related note, while P0011 is intake valve timing (IVT) the diagnostic path has you checking crank sensor and then cam sensors. This suggests that while not getting a specific cam sensor code, they can be bad or something related to their function is causing this code.

I replaced my bank 1 CPS with a cheapie unit and although it put out all my VDC, SLIP, and CEL, my CEL later retruned and have new P0011 code. Has anyone got this and found that it was the cheap 3rd party replacement sensor?

My car has that light on randomly too. Is it common in these cars ? I just bought mine I had a 350z before but it's different

if you are saying you are seeing all three lights on its probably one of the CPS. You should probably pull codes and see what is stored in the EC before doing anything.

@miketyler thank you I'm going to look up the codes tomorrow !

Is anyone from so cal ? That knows how to work in this ?

hey GG - did you take to AutoZone to find out what codes were stored in the ECU?

Hey do u have a any idea why my vdc switch not turning on my vdc and my slip light is on?

brakes fluid is at medium and tires good.

Hook up a scanner and check for codes.

Thanks for the information
 

All,

My hearty thanks to all of you to take time and share information on this forum regarding P0340 error. I was having a similar trouble when my car almost stalled on me on I-95 and VDC light Slip Light turned on.. Took it to a Japanese car expert and paid $227 for Cam Shaft Sensor Replacement. The car is starting again without a problem and no noticeable problems. :JAMIN:

How much to fix
 

my slip, VDC, and engine light came on. i know what the problem is but i dont know how much it would be to fix it, i cant fix it myself so does anyone have an idea how much it would cost to pay a mechanic. i have an 03 G35 coupe

Hey guys, this morning around 3am i was driving home and the slip, vdc, ses, oil, and battery light came on.
The car stalled and i was able to park it into a small street. About two hours later i went to go pick it up and it turned on and i drove it home. I ran the OBD2 and pulled up P0340.
I changed the sensor just about an hour ago and it lagged to turn on but it did.
Drove it and it felt different as in it gained some throttle. Besides that, it wont turn on as fast as it did before all this happened? Is there something else wrong?

Did you buy an OEM sensor or aftermarket? The cam sensors are notorious for causing issues if you don't go with OEM.

I bought an aftermarket. Nappa to be exact.
I didnt have 160 for the oem at the dealer.
Update. i got home and it threw P0011.
I went back to the p0340 sensor and turns out it wasnt fastened tight enough. the car runs and turns on fine. But i cleared the code p0011 . should i get that checked?

sounds like my problem. Gonna have code read
