I just replaced that sensor; I replaced it when I installed my new downpipe and cat back. Previous owner had installed a bad after market down pipe and cat back. I used a Bosch 17319 for that sensor and the code on my reader said that the O2 heater circuit was not working. I am able to clear the code and I cleared it last night. It popped back up this morning when I was leaving for work and I was able to clear it again.
