Not to the best of my knowledge. That code is set when the long term fuel trims are nearly maxed out. Possible causes of this are:

intake air leak, exhaust leak near o2 sensor, low fuel pressure, bad oxygen sensor, leaking fuel injector or injectors, dirty or faulty MAF, too much engine oil or contaminated engine oil.

what should the parameters be for the o2 sensors

That I am not sure of, but if you would like, I can submit an offer to email you all the diagnostic information about this code for 5.00 in PDF format.

Have you gotten this taken care of, or is there anything that I can do to help?
