Fault codes only tell you the circuit or system that needs further diagnosis, never the exact part. If it were that easy we wouldn't need mechanics with diagnostic skills.
In fact, the sensor in the circuit related to a fault is actually the cause of the problem about half of the time. The other half of the problems are caused by things like spread terminals in a connector, corroded terminals, corroded splices, cut wires, and things like that.
Before we continue, we need to be clear on the exact symptoms because "doesn't start" can mean a lot of different things. Does the engine crank, (turn over), but not start, or does it not even crank? What did you find for battery voltage? If it doesn't crank, do you hear any relays clicking under the hood when you try to crank the engine?
