Question about 1997 Saturn SL
Code reader goes on"Bank 1, Sensor 1". Does this mean the O2 sensor needs to be replaced?? HELP, PLEASE.
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

Oxygen O2 Sensor Circuit Low Voltage (Bank 1, Sensor 1)
What does that mean? Essentially the same as P0136 and P0137, a P0131 code refers to the first oxygen sensor on Bank 1.
P0131 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 1 Sensor 1 is located in front of the catalytic converter.
Symptoms There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
Causes A code P0131 may mean that one or more of the following has happened:
