NEED HELP WITH A FI CODE!! C44 heated o2 sensor

[Chance]

Fellas I need some help here. Just finished getting my swb gen2 painted and putting it back together. Had some older MRXO1 in an older but sealed can so I put it in the tank. Buttoned it and started it, after about 5 sec the FI light came on and staying on. Threw code C44 for the heated o2 sensors.

Only thing that I did was:
Installed hid's low and hi's
Painted my ceramic coated pipe w/ black gloss engine paint

That's it. Has always ran perfect with no probs. I have not ridden it to see if the code would go away yet as we'll. It's starts and running fine when revving up?

I'm stumped here. Any ideas on what this could be?

Quoted verbatim from manual....other than copy/paste I can't help much with GenII.....

C44/P0130
HO2 sensor

HO2 sensor output voltage is not input to ECM
during engine operation and running
condition.
(Sensor voltage > 1.0 V)
C44 (P0130) is indicated.

Check for: HO2 sensor is circuit open or
shorted to the power source

C44/P0135

The Heater can not operate so that heater
operation voltage is not supply to the oxygen
heater circuit, C44 (P0135) is indicated.

Check for: Heated circuit open or shorted
to the ground
Battery voltage supply to the
HO2 senso

wow. There is a lengthy process for checking the device. I suggest downloading the GenII manual and read pages 1A-102 through 1A-107....good luck!

Flash the ecu and turn it off

Flash the ecu and turn it off

Will it still run fine with it on or does it have to flashed and turned off first? I need to find someone to flash it for me I guess
