Hi AWilson,

These are ABS codes. By themselves I would think you have a weak battery. These are not related to each other so I would start with charging your battery and then retesting. More than likely if you clear them after charging the battery they will not come back. If they do then we can dig deeper. Let me know what you find and we can go from there. Thanks

31-02 PFINH Signal Failure
34-02 TP Reference Voltage Failure
