Trouble code p0141-heat oxygen sensor bank1 sensor 2


Hey I had a similar problem with my '02 Focus. The problem was the actual wiring into the distributor. The wire into cylinder 1 and 3 broke (but were very difficult to see) and was giving me codes as well. Pretty common problem in that age of the focus. It made my focus hesitate and chug until the temps came up. I went to the junk yard, found a focus with a rewired module (with a heavier gauge wire), replaced it and magic. Hope that helps
