  • P1519 Check Engine Light

    I recently got my car running after it was sitting for nearly two years. It had several codes when I first got it, one was P1519 and the rest were misfires. I ended up replacing most of the fuel components, intake & vacuum lines, cooling system, and a Dr Vanos unit with reman/tested vanos solenoid. After all this, I still have the annoying P1519 code. The vanos solenoid was tested and worked and the motor was timed with the cam blocks. The camshaft position sensor was also replace with a brand new OEM unit.

    The car also has a rough idle at start up, until it's warmed up. Beside the CEL and cold start idle, the car drives fine. So what could be causing this code?

    Who installed the vanos? You sure the vanos was set up correctly?
    Cam sensor?

      I did the install and followed the provided steps, from Dr Vanos, to a T. I'm no master mechanic, but I do know how to wrench. I aligned the cams twice to make sure the cam blocks sit flush to the back of the block. The camshaft position sensor is a brand new OEM unit from FCP.

      With that said, could there have been anything I did wrong with the install?

          I have the same issue, VANOS mechanical jamming. No CEL present and no symptoms but there is a stored fault code. Gonna try this first since it seems like its best to try the cheap and easy things first:

            I'll have to check that out enlarging the reluctor wheel. As I mentioned before, I purchased the car with several CELs and the PO wansn't able to clear them. The PO also said the car may have aftermarket camshafts from Dynasport Racing, I wasn't able to locate much information about them.

            Thanks for everyone's input.

              When I rebuilt my vanos I found getting the vanos installed properly took me a couple of tries to get everything aligned correctly. I'm sure once you have done 3 or 4 times it feels easy, but the first time I found there are several points where you could be off by one chain link or by one spline, etc. Using the cam blocks and setting the cam in position was the easy part.
