"DTC Fault Type" is set to "3: No Reporting" for both codes. Stock value was "2: Service on" for both.
"DTC Fault Enabled" is set to "0: Disabled" for both codes. Stock value was "0: Disabled' for both.
I've been turning off codes by setting them to 3: No Reporting and it has worked great for the Rear O2 sensor, EGR valve, and all the other EVAP codes for that matter. Am I doing something wrong?
One thing that may be unique about my setup is that the EVAP wires aren't connected to the PCM at all. Technically that shouldn't matter, but it could be why others with all the wiring/solenoids in place may not get these particular codes.
I found the service manual definition of these codes, and the computer is checking to see if there is 12V on the PCM pin that each code is monitoring. Basically to make sure the solenoid is present and that there are no opens or shorts in the circuit. I could trick the computer by sending 12V through a current limiting resistor to those pins.
