Hi, i have a 1995 Camaro 3.8. And ive been getting this P1442 EVAP Vacuum Switch High Voltage During Ignition On for about a year now off and on, so i replaced my fuel cap but that didnt fix the issue. So last mouth i took it in to a machanic and he said he found a bad hose and changed it out. So i thought the problem was fixed. But yeasterday the code was back. So now i need to know where the vacuum switch is located so i can see if i can fix this issue.
