O2 sensor?
this morning my car just threw a check engine light at me:
P0137 O2 Sensor Circuit Low Voltage (Bank 1 Sensor 2)
how critical do you suppose that thing is? I figure at worst it might affect my fuel mileage, but I could be wrong I suppose. Think I should have someone else drive to kokomo after school today (60mi round trip)?

Actually its fairly important. And most definately will affect performance. The PCM will determine fuel strategy by use of that sensor. For example, if reading low voltage says to the PCM..."lots of oxygen" the PCM will correct by adding fuel. If high voltage says "not a lot of oxygen" it takes away fuel. It does this to try to maintain center (high/low switching). Yours may end up running too lean or too fat.

A failed sensor 2 on either bank will not cause a false rich or lean condition.
