95 Voyager 3.3 engine 4 speed automatic 208,000 miles.
Friends vehicle, the check engine lite has come on intermitently. Checked codes are:

12- (disconnected battery) I know the battery has not been disconnected. I will try cleaning up battery cables and posts, seems like on this vehicle this needs to be done more than usual. Could this be a bad ground someplace??? This code has me stumped.

32- (2 seperate codes) Short or open in the EGR solenoid circuit. I will check the connector for looseness. Engine runs fine no problems, mpg seems to be the same.

Any ideas, thanks
