Want to remove the rear o2. I've been trying other non V7 rom patches and can't seem to get them to work, still throwing DTC: P0037.

 

Really all of these people with V7 and no one knows of a fix for the CEL?

 

The following post should help you disable the HEATER CEL (P0037).

This is the code you will need to add to your xml to disable the CEL. Plug this in, open your rom, flip the switch, and viola!

edit: same info he posted above

 

^That's the first code I tried and it didn't work at all. I've also tried to do the Pass all inspections code and it didn't do anything.

 

Are you clearing the DTC so that the CEL goes away every time your make a change? I doubt the following fixes will REMOVE the CEL after it has been triggered, their purpose is to PREVENT the CEL from being triggered in the first place.

Try clearing the ECU by removing the positive battery terminal for a few minutes and then see if the CEL returns after a few driving cycles.

Do you have the "Enable RearO2 Simulator" option enabled in your "Tephra Mod Options"?

Attached are the settings I have in my ROM:

 

I'll post up some pics of my rom tables when I get home tonight if I can't get it working. Pretty sure they look they same though, but I could be wrong.

Yes I was using evoscan to clear the DTC codes prior to flashing the rom with the new xml tables.

 

I added the code you listed, checked my maps and I "think" it's finallly working! Thank you very much sir. I didn't realize I had to [ the 1 in the heater CEL enable box. This is my first patch besides V7 that I have ever applied.
