Roland@pcmtec Posted November 26, 2019 Share Posted November 26, 2019 Set the following to No Error auF2164 P0136 - Oxygen Sensor Circuit Malfunction (Bank 1 Sensor 2) auF1845 P0138 - Oxygen Sensor Circuit High Voltage (Bank 1 Sensor 2) auF1127 P0141 - Oxygen Sensor Heater Circuit Malfunction (Bank 1 Sensor 2) If you have a V8 you need to set the Bank 2 Sensor 2 as well. Then to disable the rear o2 logic itself set the following to 1 auF2440 Calibration switch that will disable FAOSC (DISABLE ->1 or ENABLE -> 0 ) If you want to disable the heater output for the rear O2 sensor (eg you have the plug chopped off or some other reason) then you can set the following to 0 for the appropriate sensor auF12158 EGO heater hardware present switch array. 1 Quote Link to comment Share on other sites More sharing options...

Cannot find scalars:- auF2440 auF12158 to disable them what am I missing ? I also changed auF0011 to 0 no rear sensor is this required ?
