2003 Chevrolet Impala 3.4L MIL Lamp on
Posted to GM Driveability on 8/24/2006 5 Replies

Hi Guys, I have a hard code on this one PO452. I have 5v ref signal at all the spots on the computer. I back probe 30,32,33,34. I'm not sure what the voltage should be at 55 and when I follow the wires 11,14,21 what are those values. I understand the EVAP code...
