I HAVE HAD THIS CODE ALSO MINE WAS A "GROSS LEAK IN THE FUEL EVAP SYSTEM" ALL SUMMER LONG THE LIGHT WOULD STAY ON. WHEN THE TEMPS GOT COLD I RESET THE LIGHT AND IT HAS NOT BEEN ON FOR LIKE 2 MONTHS NOW AND WAS ON BEFORE FOR LIKE 6 MONTHS STRAIGHT. I COULD NEVER FIND THE LEAK.

I GUESS IT MUST ME A VACUME LINE OR FITTING SOMEWHERE. AND WHEN IT GOT COLD MAYBE THE LINE SHRUNK UP AND TIGHTENED ITSELF TO THE FITTING ENDING THE LEAK.

CHECK THE ELBOWS ON THE LINES THEY ARE USUALLY THE PROBLEM. THERE IS ONE UNDER AND BEHIND THE POWER STEERING PUMP THAT GOOES INTO THE INTAKE MANIFOLD IT IS A COMMON PLACE FOR A LEAK.

THE LEAK CAUSING THE CODE WILL NOT EFFECT HOW THE CAR RUNS BUT IT WILL NOT PASS EMMISSION'S TESTING THIS WAY. i ACTUALLY RESET MY LIGHT IN NOVEMBER WHEN MY EMISSIONS STICKER WAS DUE AND AFTER I RESET THE LIGHT I WENT AND PASSED THE EMISSIONS TEST AND THE LIGHT HAS BEEN OFF EVER SINCE.

WHO KNOWS WHAT CAUSES THESE STRANGE CODES TO APPEAR AND DISAPPEAR?

I EVEN REPLACED MY GAS CAP LAST SUMMER JUST TO RULE IT OUT, AND IT WAS NO HELP.

GOOD LUCK, CHECK THE VACUME FITTINGS AND GO TO WWW.VOLVOSPEED.COM AND GO INTO BAY 13 THEY SHOW SOME OF THE COMMON PLACES TO LOOK
