The code is basically saying that it is taking a longer time than specified for your O2 sensor to take a reading. This is probably an indication of age, but could also mean that there's a bunch of crud coating it.
Tom used an appropriate sized wrench and undid the third O2 sensor, cleaned it off with throttle body cleaner, let it air for a while and popped it back in. I'll see if I get the code again. If so, then I'll just get a new O2 sensor later on in the Spring...

Old school bump!
Pulled this code today from my SVX:
P0145 - O2 Sensor Circuit Slow Response (Bank 1 Sensor 3)
I did recently have 3 spots on my exhaust system leaking from welds when this code was active. They have since been repaired. I just reset the computer about 10 minutes ago. Will consider removing this O2 sensor, cleaning and re-installing rather than replacing. Just bumping as a reference so I can find this thread easier.
