Did you erase the code and then it came back? Check with auto parts store to see if they say 1 or 2.

SOURCE: Code: P0133 - O2 Sensor Circuit Slow Response Bank 1 Sensor 1

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.

Is there a knock in the engine? If the motor rattles, the knock sensor will think its pinging and retard the timing to compensate. This will set the code.

Location of knock sensor on a 1998 Saturn 4 cylinder


A knock sensor is threaded into the engine block and is supposed to sense when the engine starts to ping or spark knock and reduces the ignition timing accordingly.The knock sensor is located on the side of the engine.
  • Turn the ignition OFF.
  • Raise the vehicle.
  • Disconnect the knock sensor harness connector.
  • Remove the knock sensor attachment bolt and the knock sensor.

  • Important: The larger metal contact area of the knock sensor MUST be toward the engine block. DTC P0327 may result if the sensor is installed backwards.

  • Install the knock sensor and attachment bolt with the larger metal contact area toward the engine block.

  • Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.
