P0136 & P0546......

I know one is a Rear O2 sensor malfunction, not sure what the other is. Does the CEL FIX include rear O2 sensor?

In case you need to know, i have a vf34 setup (catless), stock TMIC, Ecutek tuned by Mike.

TIA

P0136 is the rear O2 sensor like you stated, but a CEL fix won't fix it, that's for P0420. Your O2 sensor is possibly bad and needs replacement.

P0546 is for the EGT sensor, either remove it entirely and replace with a bolt or leave it and then place a resistor in the plug and you should be good to go.

Or talk to Mike and see if he can turn off those codes in the computer so they don't return.

Is it vital that i repair the rear 02 Sensor? Im selling the car so i just want to make sure i dont have any more CEL popping up.
