1999 Saturn SL2 OBD codes

For the p0133 that's ur front o2 sensor u will need to replace the o2 sensor in ur exhaust manifold to fix that code. On ur p0341 that's the cam signal postion sensor which the car doesn't have it's usually plugs and wires if u take the spark plug wires off take a bright flash light and look into the boot end that goes onto the plugs look for a black powder that's carbon if u have some replace the wires. Also remove ur spark plugs and if u have black spots on them that's does wipe off or tip that goes into the engine is worn replace those as well. Let me know what u find.
