Welcome to the Forum. In the future, you're better off posting questions about your vehicle in the Voyager forum. This forum, as it says, is for forum issues, not vehicle issues. Anyway...

12: Problem with the battery connection. Direct battery input to PCM disconnected within the last 50 ignition key-on cycles. (Nothing to worry about if you recently disconnected the battery.)

27: One of the injector control circuit output drivers does not respond properly to the control signal. Check the circuits.

have disconnected battery has had poor connection. light went out.came on again after sitting idling for 5 mins. thanks for reply
