Right now im just want to monitor my AFR (no datalogging or uberdata installed) and I used the wideband 02 sensor in place of the stock one so I had to splice the 02 wire on the ecu with the gray wire from the plx, but I get code 41 "Primary oxygen sensor heater". Is that normal?

 

yes, because the plx sensor isnt heated

 

So i shouldnt worry about it? It doesnt affect anything right? I will install uberdata soon but right now i wanted to get a feel of the AFR's on the stock ECU.

 

You need to disable open loop & o2 heater in UD.

 

i understand that but i just wanted to know if i can run as is for now, untill i install uberdata. will code 41 affect anything?
