I currently am running my AEM wideband in the front o2 sensor spot, with the closed loop control, with the factory one unplugged. Is there any way to disable the front o2 sensor, I am getting the front o2 sensor heater circuit CEL and would like for that to go away.

 

In the ECU Periphery2 (FCA) Bits, change bit 11, 6, 3, and 2 from 1 to 0.

 

I'm attempting to just disable the heater and from searching I've seen to change periphery0 FAA bit 14 to 0 and/or the value 56DA to 16D0. (I'm a little confused on terminology)

I had p0135 pop up so I got a new o2 and after clearing the codes it comes back immediately on start-up. Does one of the bits you suggest changing affect just the heater?

Could you define which bits you listed affect what function since I'm not looking to disable it completely, just the heater?

Thank you!

EDIT: I saw it mentioned on changing bit 14 to 16D0 that it also disables the immobilizer and something else. I do not wish to disable the immobilizer.

 

Can anyone help me with this?

 

If you change bit 14 from 0 to 1 it shouldn't affect the immobilizer. This is different to changing periphery 0 from 56DA to 16D0. That affects several of the periphery bits, not just bit 14.

 

Thank you for the clarification!
