I JUST HAD THIS PROBLEM COME UP IN MY 1999 SL2. I WOUND UP REMOVING THE BELLOWS ASSY. OFF THE AC BRACKET AND CLEANED OUT THE STAINLESS STEEL TUBE CONNECTED TO THE EXHAUST MANIFOLD. THEN USING A VACUUM PUMP PURCHASED AT AN AUTO PARTS STORE, I CHECKED TO SEE IF EACH INDIVIDUAL PART WOULD HOLD VACUUM.(THE PUMP COST $32.00). I FOUND THE HOSES TO BE POROUS AND NEEDED REPLACEMENT. THE SOLENOID CHECKED OUT, GOOD. THE ONLY QUESTION I HAVE LEFT IS THE BELLOWS SUPPOSED TO OPEN WHEN VACUUMS APPLIED. SO WHAT WOUND UP HAPPENING IS I CLEARED OUT THE ERROR CODES. THEN CHECKED TO SEE WHEN ENOUGH CODES RESET THEMSELVES TO PASS INSPECTION.(USING MY PLUG IN OBDII READER, PURCHASED FOR $60). THEN CHECKED THE MILES IT TOOK FOR THE LIGHT TO COME ON.I RESET THE LIGHT DROVE 50 TO 60 MILES MOST OF THE CODES RESET THEMSELVES AND GOT IT TO PASS INSPECTION. YOU ARE ALLOWED TO HAVE TWO CODES INCOMPLETE TO PASS. THE P0410 CODE WOUND UP COMING BACK ON AFTER 100 MILES OF DRIVING.I HOPE THIS HELPS IT TOOK ME ON AND OFF OVER AMONTH TO TROUBLE SHOOT.

The most common reason for the code is the combo valve on top of the ac compressor that has the tube going to the exhaust manifold doesnt hold vacuum. You pull about a 20 inch vacuum see if it holds thats where I would start.
