(Local costs for an OBD II code reader average about $250 CDN) but the odd thing is, this failed O2 sensor does not seem to affect the car's performance at all, so I am going to leave it until I can scrape up more $$.

Anyone have any opinions on the wisdom of leaving the failed O2 sensor repair for a couple of months, assuming no performance degradation and realizing that I may burn out the CEL bulb...?
I wouldn't worry about it. honda disconnected their O-sensors for years, to bump their reliability ratings.

The only problem is, if a real problem comes up, you won't know it, -but keep an eye on your guages, and your ears open, and you should be fine.

I drove a company car with the o-sensor cel light on for years.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion. Jer 22:13, 15-17
