    My P410 code comes on almost every day. I heard you can bypass the valve on top of the exhaust to the Air pump. Do I diconnect small hose on this valve and plug both ends

    and is it the one with silver flat top with one big hose(to ai
    pump) and tiny hose on it , just behind engine center facing UP fro
    exhaust? Small hose points towards drivers door. Mine is a 1997 850 GLT

    thanx Chri

    If you don't want your light to come on, the only way is to have a
    working pump. The valve you're talking about disconnects the exhaust
    from the pump so it doesn't fill with water and other combustion product
    when the pump is off. The pump will work for a little while without
    this valve in the circuit, but not for long. If you need readiness
    codes for your emission test (test via OBD-II port) then you'll have to
    fix it.
