Check Engine Light & P0141 After O2 Sensor Replacement

[onemanarmy]

I'm still battling mine as well.

I've sent my ECU in for testing/repair (if needed)

From my understanding, the simulators are for O2 sensor readings (emission levels) and the heater would still be in the circuit with the simulators. They are useful for removing the CAT and not for the 'heater circuit' codes
