This could be related to the manifold absolute pressure sensor (MAP). Let's start by checking it. First, check the connector and wiring at the sensor. I attached a pic below to help you locate it. The code indicates a low voltage issue. That could be the result of corrosion in the plug.
Let me know what you find or if you have other questions.
See pic below.
