yes i would recommend replacing the o2 sensor, 9 times out of 10 it will correct the problem and they usually aren't too expensive for the saturn's

it may be a defective O2 sensor here is th difinition:
P0133 - Heated Oxygen Sensor (HO2S) Slow Response Bank 1 Sensor 1 , this is the sensor on the side of the engine that #1 cylinder is on, it is the sensor before the cat.

is this a 4 or 6 cylinder?
if a 4 cylinder it will only have 2 o2 sensors
V6 will have 4 o2 senors which the sensor will be the right side of the engine first sensor.
1st sensor on exhaust, I recommend if you change one change all, as this will make the computer when it rechecks the system you have all clean/fast responding sensors.
if you have a slow response it means the sensor is dirty and not reading well, which is usually caused by minor misfires that the engine computer dismisses, so a tune up would be recommended too.

O2 sensor are located before and after Catalytic Converter ( exhaust system of your car). If you car's engine is 4 cyl you have 2 O2 sensors and if you car's engine is 6 cyl then you have 4 O2 sensors ( for each bank, 2 for left bank and 2 for right bank). Hope it helps and comment if you need more advice. Please don't forget to rate the answer it helps with my ratings, thanks!
