I plugged in my AP ver2 and i have a p0453 which is Evaporative emission control system pressure sensor high input, i searched NASIOC and this is the closest i could find http://forums.nasioc.com/forums/show...ighlight=p0453 towards being any help for me. My question is what these other suby guys sayin is true about fixing, or is it just a ghost code...i also read maybe it's my gas cap? The car is running fine btw. Hmmmm. If anyone has any input, that would help me greatly. Thanks!

 

could be the gas cap. try taking it off and putting it back on. make sure it clicks at least 3 times. reset the ecu and see if it comes back. if it does then it may be the sensor needs to be replaced.
