I looked around online but I couldn't find anything. I would call my salesman or dealer and ask them what the code means.
Not sure on the message, but mine whistles also. Would love to know what they say the cause is.
My 07 crew cab has a high pitched whistle from under the hood, more noticable between 14 to 40 MPH, during acceleration and less to none at idol. Is this the accelerator thing I read in another, was anything done for this? Nothing to do with the altinator?
