2005 Neon Oil Pressure Problem

My 2005 Neon sxt has about 80K miles. I am getting the oil light on when I come to an idle. Goes off as soon as accelerate. Fresh oil and filter. I was going to start the oil sending unit. Does this sound reasonable? Where is it located? Does the Haynes manual show it well (I don't have it in front of me)?

Back side of engine, low. If you have a wiring diagram, match the wire colors at the connector, to be sure. You may need to use mechanical gage to take oil pressure reading, then compare readings with regulator gage.

thanks for the diagram. What is the best way to get to it?
