I have these code on a 1999 v-70. P0328 Knock sensor, P0506 Idle Cotrol System RPM Low and a P1081. Does the knock sensor have one plug on the end of two sensors that go on the block. How do I go about fixing the code for the Idle control. What is a P1081. My reference does not go that High. Does my PVC valve located on the left side of the intake manafold next to the alternator. And is it called the PVC Hose Nipple. In the parts book it looks like it screws in the side of the manifold and has a connector on the end. I want to be sure before I order these parts, because I know the from want I read that it is a timely job.

Thanks
BOB

    The p1081 is an immobilizer code. It was set when the technician tried to start the car with the scanner already plugged in. Either ignore it or clear it, it does not turn on the CEL.

    This is a turbo engine you are describing? The PCV system you are describing sounds like it. The oil separator box is on the alternator side, and there is a vacuum line attached to the intake manifold with a clip.

    The two knock sensors have upgraded wiring and plugs. I would call the parts people you are dealing with just to be sure.

      Thanks for the info. I have a Non-Turbo (B5254S) 2.4L
      I checked with my parts people and he told me the right one to order.

      As for the PVC, I just have to see what I have when I remove the manafold.

      Things are a little close in there and I really can't see that much with a mirror.

      Thanks again,
      BOB

        When you remove the intake manifold, note the position of both knock sensors. The new ones must have the wires coming out in the identical directions as the old ones.

        You do not need to remove the injector rail from the manifold. I suggest keeping the injectors in place, just loosen the fuel lines at the top and backside of the block. Then flip the manifold up, out of the way. Should save you at least an hour of additional work.

        Also, when you remove the bolt for the dipstick on the manifold, remove the bolt for the manifold bracket which is right next to it. When reinstalling, do not tighten down the manifold bracket bottom bolt until the top bolt has been secured.
