Launchpad P1.3 Voltage Problem

I'm using a MSP430G2553 for a sumo robot. I currently am using P1.3 as a GPIO pin to drive motors via a L298N motor controller. I have four GPIO pins in total that I am using for this, and they work wonderfully and are able to activate the motors. P1.3, though, will not. I checked the pin voltage, and it reads ~270mV, instead of ~2.5V. The wire wrapping looks great, but the voltage is just too low. Does this have something to do with P1.3 being connected to S2?
