I recently straight piped my 2009 Fusion SE 2.3l. It sounds amazing but my O2 sensor is throwing codes causing it to run rich and I’ve ran into a couple problems. I’ve looked for dummy o2 sensors but I can’t find any specifically for my car. I was wondering if anyone had any experience like this.

Hey i’m having a problem with my 2015 ford fusion ecoboost. Its throwing a p0141 code which is for a o2 sensor. Bank 1 sensor 2. I replaced it and its still giving me the same code. I tried resetting the code and it came back on. I hooked it up to my forscan live data and it gave me that the htr12 is at fault. Ill include a picture for anyone that knows a little about forscan diagnostics tool

Hello, I have a check engine light producing two codes: P0141 - O2 Sensor Heater Circuit ( Bank 1 Sensor 2) P0054 - O2 Sensor Heater Circuit Resistance I am having a hard time finding any repair manuals or guides to replacing the sensor efficiently without disassembling too much of the intake assembly covering the whole back. I figured out that the sensor is before the Cat Converter as it is sensor 2. But I am not sure if the O2 heater circuit has a fuse associated before I directly go to replace the part. I would like to know if there is a fuse and if so, what fuse is it? Also how long would it approximately take and what would be a reasonable cost to repair at a shop that isn't a dealership? The Ford dealership is wanting to charge $386 with parts plus labor. Thank you, -
So, driving home from work on Monday, my Check Engine Light came on and I stopped at the first AutoZone I saw. They pulled the following code and provided the following printout: Definition: P0171 - Fuel trim bank one condition lean. Explanation: The powertrain control module uses the oxygen sensor to calculate the Air/Fuel ratio of the engine. The computer as recognized a rich or lean condition on one engine bank. Probable Cause: 1. If bank one and two codes set together suspect fuel pressure or MAF (Mass Air Flow) sensor 2. Oxygen sensor defective 3. Ignition misfire-repair 4. Fuel injector problem As I was only receiving the single code for bank one, the next most likely cause is a defective Oxygen Sensor. Since it was relatively cheap and I just passed 101,000 miles, I figured there was no harm in replacing it as a first step. The problem is this... I understand that Bank 1 is the side of the engine closest to the Firewall, but I couldn't find any diagrams online of where to look for this particular sensor. And on the firewall side of the engine, there are two easily-accessed sensors, which look similar and I believe have the same electrical connection. However, I have no idea which of these two sensors is the one I'm supposed to be replacing, if they are in fact the ones I'm looking for. I'm looking for suggestions or further insight?
