My car is reading the map sensor

I disconnected the battery for 12 hours won't that reset everything?

And the car is still running the same also

Ok so if it is the ground do I just run one straight from the battery for what should I do?

Thanks alot

Thanks for your vote, rereading, i must mention that no jumper wires or circuits need be added to a system of this type during testing unless directed to do so by the service manual. that can be a mindblower. Enjoy your car, have a great day.
