You are wrong.
But try disconnecting it and seeing if it clears up the problem.
Can you elaborate on the O2 sensor influence on ECU?
When (cold or warm engine, idle, partial load, WOT)?
How (change timing, injectors, boost)?
The code says Sensor Heater Circuit Electrical Malfunction. Bad heater (circuit) leads to bad O2 sensor signals which (can) lead to instable idle, extremely poor running partial load (no load revving is not so bad)?
