Default CEL help!

I've just took off my vortech kit off the car, and started the engine with everything stock.

CEL light came up and I have scanned it and it says

HO2S S2 Heater Failure.

How can I fix this? It wouldn't go away by resetting the ecu...

O2 sensor is bad or the wires going to it or to your ECU are not in working order.
