    Hello Ray m,
    We wouldn't recommend replacing anything just yet. See what others have experienced with your vehicle and this code. It could be quite telling... Here are examples of what we mean:

    A diagnostic flow chart from the factory service manual would most likely be your next step (advanced diagnosis is beyond the scope of our manuals). For that information, try this site www.alldatadiy.com (http://www.alldatadiy.com) .
