Know the p0455 code means an evap leak or gas cap. Is it at all possible that a coolant leak from the condenser that started at almost the exact same time could throw this code? or is it just that they both started at the same time but are unrelated? wood a loose exhaust manifold cause this.. P0455 is supposed tone a large leak in the emission system. so I wouldn't think so.

crawled under the vehicle checked the eval can no obvious leaks no cracks hoses nada, checked the gas cap seems ok can t smells retighened it and tried to bank the go ,,, no go... go the battery disconnected now waiting the 30 minutes to see if that will reset it.... we shall see

 

disconnecting the battery did the trick all is well except for the coolant leak
