Default Can't find the answer to this code

I cannot find the definition for the P140 code. I've had so many problems with my '01 PT Cruiser, just got it back on the road 2 days ago after an engine rebuild, this code started yesterday after we had put about 100 miles on it. It seems vaguly familiar, but I don't remember what it is

Oxygen sensor fault code (when you look up the code it should have 1 letter and 4 numbers (P 0140

P0140 HO2S Circuit Insufficient Activity Bank 1 Sensor 2

Check to make sure whoever rebuilt your engine replaced and hooked up the 02 sensor.

jennylyn, there has to be another number for the code. Did you get this code using the key "trick". I would suggest you take it back to the person who rebuilt the engine.

If it is p0140 then it's not really the engine builders fault. It's the 02 sensor thats worn out. What happened to the engine to need a rebuild?
