I'm running OFT v2.061 E85 UEL Stage 2 tune with a UEL catless header.
I was running at the track today and got a P0037 and P0141 check engine codes, putting the car in limp mode and ending my day:
P0037 - HO2S Heater Control Circuit Low Bank 1 Sensor 2
P0141 - O2 Sensor Heater Circuit Malfunction
I metered the two black wires on the rear O2 sensor (black connector), and it's reading open resistance / dead. I'm about to go pull off the undertray and see if there's any visible damage to the sensor or wires. I've had no luck finding a replacement O2 sensor on the weekend so I can keep running tomorrow.
However, It looks like I can disable those codes in RomRaider.
My question is - will the dead rear O2 sensor affect the engine performance on an OFT tune, or is it just to check cat efficiency? If I disable those codes and re-flash it for just tomorrow, will the engine run properly? I'd like to get one last day in, but not at the expense of an engine.
Thank you!
