The check engine light is on the Auto Zone computer listed a hex code 3e but with no definition Do you know what this code is?

Chilton's manual shows 3E (PO 132) as the left upstream oxygen sensor shorted to voltage.The oxygen sensor input voltage is too high. The problem is in the oxygen sensor itself. (must be replaced) or in the Mini computer unit (MCU) The MCU controls input voltage to the oxygen sensors to control fuel flow. Good Luck I hope this helps

How do you know when oxygen sensor is bad?

An oxygen sensor is bad when it is no longer performing inside a set of parameters that are designated and optimal. The oxygen operates in a very narrow window of voltage and provides feedback to the engine to adjust the air/fuel ratio to maintain performance and emissions. If the sensor is bad and returning poor data, the performance, emissions and mileage will suffer.

Where is the oxygen sensor 1 on a 1997 Saturn SL1 and is it hard to replace?

Oxygen sensor #1 screws in to the exhaust manifold just before the headpipe. The hardest part about replacing an oxygen sensor is screwing it out. Sometimes they are a little siezed in from the heat. after you get the old one out, you'll need to make sure you know how to electrically connect the new one. Some of the replacement oxygen sensors have a plug and others need to be spliced in. Just make sure you connect the wires correctly, following the color codes or the directions that came with the replacment sensor. It's relatively easy and a good first auto repair project.
