The other day my little CEL light popped on, once I got home I pulled the code from Learning View and it said P0031 Front oxygen (A/F) sensor heater circuit low input. I pulled up the logger in Romraider and my Front AFR is stuck at 14.70 and doesn't move at all. The Front o2 current and heater current is at 0 and the resistance says 255ohms. I did some troubleshooting and have pretty much come to the conclusion that the sensor is toasted. My question is, can I replace that front sensor with a PLX-AFR and use it's narrowband output?? I'd like to add the wideband but I don't want to if I have to buy another stock front sensor. Thanks
I would not. It will not read as well in the stock location and will most likely not be able to handle the conditions for long.
