i have p0404 p0442 p0341 p0573 p0731 errors codes and my engine light came pretty recently. car runs smoothly and nothing seems to be wrong except engine oil was low when this light came on. my car is 2002 Saturn SL2

Answer 1

P0404 Exhaust gas recirculation (EGR) circuit/range

P0442 Evaporative emission control system leak detected (small)

P0341 Camshaft position sensor circuit range/performance

P0573 Cruise control / brake switch "A" circuit high

P0731 Gear 1 incorrect gear ratio

You should take care of P0404 when this EGR gets stuck open , idle becomes rough, just take the EGR out and clear the pintle. As for P0442 replace the gas cap. P0341 this will not cause any drivabilty problem, P0573 This is important check the brake light operation, make sure the brake switch works , the brake switch when engaged cancells the cruise control. P0731 this is the gear solenoids, a gear solenoid is affecting first gear.
