Has anyone ever got a PO453 EVAP CTRL PRES SEN HI IN code? Something with evap fuel tank pressure high input. I go to clear my dtc's and it keeps popping up! anyone know how to fix it..? Thanks

 

iN THE EVENT THAT THE DONT COME AROUND I'D HAVE IT LOOKED AT ASAP BY THE DEALER WHO DID THE ADJUSTMENT. iT SEEMS TO ME THAT ITS MORE OF A PERSONAL ISSUE THAN ANY THING ELSE, I GUESS THATS WHY IT PAYS TO BE POLITE SOME TIMES. rEGARDLESS, ITS NOT YOUR FAULT AND HE IS IN THE WRONG. uSUALLY THEY COME OUT FINE WITH OUT ANY PROBLEMS BUT IF NOT, I WOULD LOOK INTO BOB BARKER.

cABBAGE.
