    whining noise when reving

    Folks, this is bugging me.
    Mech says nothing to worry about.
    BUT its never been there before.

    When I rev there's a whining noise, like it goes up and down with the revs.
    The power steering also makes a noise when turning the wheel.
    Do you think maybe they are related?

    Thanks in advance

    Check PS fluid. That will make the noise. If it is low, either the pump or high pressure hose.

    I had the same thing on an 05 with a leaky hose and low fluid.

    Could be the power steering system, leaking o-ring or leaking hose which is letting air in. Also can be the intake system, check the intake tube for cracks.

    Replace the inlet o-ring on the PS pump. Also, make sure your reservoir has the white dot on it. If not, or you're unsure, just replace the reservoir (and cap) too. They're cheap. Flush with clean new Honda PS fluid and most likely the noise will go away.

    What's with the white dot? Is that a better replacement for the OEM?

    Oops, and where would you find it? Just had a PS high pressure hose installed since it was bad.

    For $120 on labor that took 30 minutes to do, and having the shop "trace" an oil leak, time to say bye to them.

    The white dot indicates an improved part. Basically they changed the filter screen in the bottom of it.

    Why would you say "bye" to the shop? The PS high pressure hose is a high failure rate item as these vans age and is different from the inlet hose. I just replaced my high pressure hose a few weeks ago.

    As part of your troubleshooting, you can remove the serpentine belt, and see if your noise goes away. If it does, at least you know the noise is related to your accessories or pulleys.

    Yeah, removing the serp belt is an excellent diagnostic move.

    If that eliminates the noise, and if you quieten the PS pump, a failing alternator can whine too.

    If the noise persists with the serp belt removed, it could be the transmission e.g. ATF pump.

    Any chance the whine is coming from the sound system speakers?

    Thanks all

    It does sound as if it could be the PS, hose/pump etc as I just replaced the hose.
