I have a 2003 Infiniti M45 and recently my service engine soon light came on so I took it to an auto parts store for them to scan it and the code P1140 came back. They gave me a sheet that said the problem is with either the left or right variable valve timing solenoid. I'm having trouble locating where it's at on the car so I can replace it. Any info?

Hi there! The factory service manual should be available for that model which should show you the location of the VVT solenoid!

Sometimes a parts diagram is worth a thousand shop manuals:
