98 S70 GLT 115k miles <p>OBD returns code for Manifold Absolute Pressure/Barometric pressure low input. <p>I'm told that the MAP sensor most likely failed and needs to be replaced. <p>Is this an item that is only available thru the Volvo dealer? <p>If there are any other cheaper sources for OEM parts like this, can someone point the way? <p>How hard is it to replace? <p>Thanks.
