CEL light...

[Dylmanner]

CEL came on this morning and when I reAd the problem with my accessport it says "02 sensor circuit high voltage. Bank 1 sensor 2"

What should I do...

A code P0138 may mean that one or more of the following has happened:
Faulty O2 sensor
Short to battery voltage in O2 sensor signal circuit High fuel pressure (not as likely)

Here are some potential solutions:
Replace O2 sensor
Repair short to battery voltage in o2 sensor signal circuit

So untill I can see my mechanic, should I be concerned driving around for the rest of the weekend?

Well, your engine will probably over compensate and run rich to prevent you from running lean and ruining your engine. If it gets bad it might run in cripple mode.
The risk is up to you.
You can probably fix it yourself with a O2 sensor from rockauto and lots of lube to remove your old one.

Drive it it'll be fine.. 98 percent of the time it needs an o2... The up stream isn't cheap.. Easy to change if your inclined mechanically...
