I know this isn't exactly FI related, but I know that alot of people in the FI section have widebands and am hoping someone can help me.. I posted in the Prelude section first, but I didn't get any response.

I've done a ton of searching, but I can't seem to find the answer to this problem..
I installed an AEM UEGO wideband and replaced my primary oxygen sensor, tapped the wire from the gauge to the ecu (stock SH ecu, not chipped), etc.. Also put a 10ohm 10watt resistor between the two heater wires (both white) on the stock o2 harness which is what a lot of people seemed to be using to trick the ecu into thinking the o2 heater was still there.

Everytime I start the car after resetting the ecu, I get a code 65 which is a secondary oxygen sensor heater circuit malfunction. I'm stumped.. I even soldered the stock o2 sensor back on (only the heater wires though, not the other two) with the idea that I would leave the old o2 sensor connected and tucked away to avoid CEL's and got the same code. Is there something I'm missing and is there a way to trick the ecu (besides uberdata, hondata, etc..)?

This is on a Turbo 97' Prelude SH, stock ECU.

 

not sure if your prelude wiring colors are like an accord, but it's the two black wires for the heater on the o2 sensor on my accord, not white wires.

I'm using 2 10ohm 10w resistors and no CEL at emissions time.

 

Oh, well I'll have to check that out. I was using a helms manual and I thought it was indicating the white wires, but maybe I'm wrong.
