My previous thread I noted this issue but no suggestions were offered. I searched around and could not find a specific solution although there was a brief possibility that my ROM may be not working with the code disable.

I am still getting the code, P0037: O2 Heater Circuit, after disabling it in RomRaider.

I have removed my rear O2 sensor and disabled the following codes:

P0037
P0038
P0137
P0138
P0139

I have also forced-passed all OBDII readiness tests.

But still, usually after 2-3 days of driving and usually on the freeway, the CEL pops up and P0037 is still ever present.

Is there a way to truly disable this, or may I have to resort to some resistor fix to fool the heater circuit?

Attached is my current ROM.

I have the same problem with my 05 Sti. Cel usually comes on when the car is maintained at a constant engine speed (stable loads) at the highway. Haven't figure out what is wrong. I do have the O2 sensor installed and plugged in.
