Nope on both parts.
It has two throttle body injectors, so no MAF sensor, and the computer uses the MAP sensor, TPS, and the coolant temp to adjust fuel trim.

SOURCE: Where is the oil pressure sensor located on a 2003

It is on the top backside of the engine block, behind the intake manifold mounted into the top of the block. You will have to lean up over the engine to see it.

SOURCE: 2007 gmc sierra 2500 IAT sensor

Well, the IAT (Intake Air Temperature) sensor is located on the air intake duct between the filter and the throttle body (Assuming you have the 6L motor). The wires are easily visible at the plug that connects the sensor to the wiring harness. That's the easiest place to access them.

The intake air temp sensor is part of the MAF sensor so yes there are 5 wires.
The two wires that go to the air temp sensor are tan and black. The other three are for the MAF.
