So I am having a few issues with installing my ZS Controller. All of the wiring is done, I have checked and checked and it\'s correct as per the the manual but for some reason when I power up the unit I get cel\'s 62 Exhaust valve solenoid (vacuum) & 65 Differential pressure sensor. The check engine light turns off when I power down the controller. Also, I don\'t know whats going on but the exhaust control valve opens when I turn the controller on which I think is the reason why I\'m getting these codes. Does anyone know why this might happen? Oh yeah car is a 94 BG5A auto. ECU is a T5. Any help would be appreciated!
