I have a 2000 Subaru Legacy L Sedan. It died while driving home. The lights, radio, and power all work, so I don't think it's the battery or alternator. I checked the belts, and the car has gas and oil. I borrowed an OBD2 scanner from AutoZone and it pulled these codes: P0328, P0340, P0420, P0031, P0336 (PENDING), P0341 (PENDING), and P0340 (PENDING). I think P0328 can be disregarded because this code has been on for years (just haven't replaced the Engine Knock Sensor). How do I know if it's possibly the CAT or O2 sensors, or something else fuel or ignition related? Any suggestions would be appreciated. Thank you!
