I'm currently showing: P0141 Heated Oxygen Sensor (HO2S) Heater Circuit Bank 1 Sensor 2-B. The car's running 1st edition LG Pro Headers with O2 sims in the rear and the rear sensors moved to the front. It's a 2002 with ~39K miles. I did a search and saw that this is one of the codes that you turn off for the rear sensors. Does this mean that one of the sims isn't working properly? Could it have something to do with the front sensors?

I also have C1288 in history. According to the list on David Farmer's page, this code is "Steering Position Sensor Circuit." Is this something to worry about?

Thanks for the help.
