Hey peep, i could really use y'all help. My moms 2000 i30t with cali emission. It failed due to the boost sensor or aka map sensor. Since mine is a 99 i30t with cali emissions i switch the sensors and no ses light on my car. So the sensor is good. So the service manual states to check for voltage at the positive and negative terminals on the boost sensor. I only get .2 volts. And i supposed to get 5volts i believe . The ecu seems fine...she runs real good at times though she hesitates. Please help Amy advice is welcome.
