the OFT is fine, the tune is fine


P0037 is
Potential causes of a P0037 trouble code may include:

• Bank 1, sensor #2 oxygen sensor heater element has failed
• Physical damage to heated oxygen sensor has occurred
• Control circuit (or voltage feed, depending on system) is shorted to ground
• PCM Oxygen sensor heater driver has failed

you need to check rear 02 sensor and wiring/plug


That's an actual fault.


you will need to do more than just disable code to remove rear 02 function, you will have to disable its compensations in tune as well as a bunch of cel codes.

I cheked the plug and wiring, fuse box got a lot of dust but i didnt see any blown fuses either. Can i measure the sensor so i know its the sensor itself that is broken. I have catless headers and the o2 sensor has a spacer.

Oh also i forgot to mension the launch control doesnt change even i change the value

write stock rom/tune back to car


do you still get the cel code.




if its all good


you likely have mismatched tune/definition or mismatched tune for your car ie incorrect calibration id

When i bought the car it had some tune already done, so i dont have the stock map for it and OFM shows that my cal id is 10G, but OFT shows 01G when plugged to car.

See the Tactrix link in colour below, at end of that post is most of the stock roms, jiust unzip them and you will be able to load either the F10G or A01G stock to your car, jist load it to one of the tune slots in oft

I loaded the F10G stock map and still get the p0037, does it have anyother fuses that 29?

Its the EFI HTR fuse


my guess would be o2 sensor was damaged during install due excessive torque applied
