I need some help guys. I have the Cattmann headers and can't get rid of these codes:
P0031 - Heated Oxygen Sensor 1 Heater Low Voltage (Bank 1)
P0051 - Heated Oxygen Sensor 1 Heater High Voltage (Bank 1)
P0057 - Heated Oxygen Sensor 2 Heater High Voltage (Bank 1)

I have a dual output o2sim hooked up to both the rear o2 sensor plug wires and the green light flashes, I assume that means that part is working correctly.

I tried some resistors w/o any luck (10W/10ohm) I tried w/ one or even w/ 2 in series for each but still get the codes.

Today I found my old rear o2 sensors and plugged them in, reset ecu, and still get these codes..

While my old o2 sensors were spliced into the oem plug, I referenced a post from The Wizard that showed the o2 sensor's 4 wire color layout being top black wire as signal, bottom grey as ground, White @ 3o clock as heater wire, and White @ 9o clock as 12V power.

I am stuck and need to get this taken care of before end of month so I can get my car inspected. If anybody has any advice or suggestions it would be much appreciated.
