First time starting car after premix.. CEL

Ok, I finally got my case of Idemitsu premix, a couple 8oz small bottles and an empty tank. I got to the gas pump, emptied 1 8oz bottle and filled up with 93.

Upon starting the car, I'm greeted with a CEL which was triggered by the following code:

Code:

Fault log report generated by Torque for Android
=================================================

Vehicle VIN: Not present
Vehicle Manufacturer: Unknown
Vehicle Calibration ID: Not present

Current Fault Log
------------------
P0037: HO2S Heater Control Circuit Low (Bank 1 Sensor 2)

Pending Fault Log
------------------
P0037: HO2S Heater Control Circuit Low (Bank 1 Sensor 2)

Historic Fault Log
------------------
ECU reports no historic faults

End of report.

I know the code is for a bad/dirty secondary O2 sensor.

This is on an 04' w/ 40k miles. Any ideas? Do I really need a secondary O2 sensor already? Since i'm under the impression that the premix addition is what triggered this, how do I know replacing the sensor will resolve this.

Luckily I don't have to stare at the damn CEL because Torque and my phone can clear it... until I start the car again.
