mm I get the code 565, during the KOEO tests.... it come sup I think as a new code, and a stored code......... I cpuld be wrong, but wouldnt the KOEO test, just test the electrical aspects of the car....making the gascap kinda irrelevant ? then again if I knew anything, I wouldnt be askin so... ? I think next I take a meter to the wires to the celenoid ot mkae sure i get some Volts there, but at what point do I check the volts. would they be constant to the celanoid or only under certain times.... and also what is the correct voltage I am lookign for here..... allllllso do I check the wires with the celanoid unplugged, otherwise how do I check the v's....
