The P2004 is for the tumble valve sensor on the intake manifold. It shouldn't cause drivability issues by itself, but there's a bulletin for it if you want to fix it:


The P0715 is what's causing your limp, it's the turbine (input shaft speed) sensor and the ECM and TCM are both freaking out because they can't tell how fast the torque converter output is spinning. The bad news is, the sensor is right behind the starter solenoid and it's a complete PITA to change out.
