Anybody have a clue what this is? Scangauge reader says P1498. Neither Bentley book nor Nathan's Diagnostic Code list shows this code. The EML and Service Engine Soon lights are on. I reset the code, and the EML light stays on but the SES goes off. I just turned 50K. Is there some kind of clock that says change the O2 sensors? Appreciate any ideas. I'd like to avoid the dealer - they leave things unbolted (like the lower engine mount...) or force brake fluid out of the reservoir when changing pads (they don't realize track junkies keep the brake fluid filled, not that 11K on a set of pads would be any kind of clue...).

(Unmetered air after compressor) Google says that NAM says P1498 is (Unmetered air after compressor) Check for leaks in the intercooler or the tube that goes from the back of the SC to the TB.
Just to add another possibility for anyone looking for information on this code down the line, I've been getting this code recurring for a week or two with no apparent change in performance. I could not find any apparent leaks in the IC boot or other tubing. When I did an oil change a couple days ago I checked my oil catch can and discovered that the can itself had broken. I did a jerry-rigged patch on the can by wrapping it completely with high temperature electrical tape which seems to have eliminated the EML light/CEL code. This does, however, open the possibility that leakage in an OCC or the connecting tubing can cause P1498 code. In my case, The code did not always appear when the EML light went on.
I found it. I have an oil catch can. I have a plastic 90 degree tube going from the hose off the PVC valve to a hose into the catch can. The plastic tube had a stress crack. Thanks everybody! Pat
I experienced this same fault code when I installed my boost gauge. The hose coming from the fuel price regulator to the t-connection for the boost gauge has popped off. I too had trouble finding the fault code.
