Could I be getting code 41 because I didn't use shielded wire to extend the primary O2?

 

hmm.. interesting... i know u need to hook up those shielded wires correctly.. cuz if not they will get all kinds of interference from random things.. but to answer ur question.. i dunno...

 

i doubt it. at least on my one-wire sensors, i've never had a problem and its unshielded all the way to the ecu. also on all the write ups i've read, i've only seen one that suggests shielded. but i guess its a possibility depending on where you ran the wires. if they are near something that would cause electrical noise (alternator wires, etc??) then your chances of interference increase.

 

thanks for the help guys.

 

running a 4 wire with unshielded wire right now. So far so good....
