Inspection trouble

I have done almost everything to pass with my test pipe and I'm not sure what the problem is

Codes o2 sensor and o2 heater, and something with catalyst
Only 2 codes show up not sure which one

Simulator is on
Ecu peripheries left alone
O2 heater patch set at 0x0009

O2 sensor is unplugged for wideband, am I missing something? This is getting annoying.

My old lancer passed with a test pipe but o2 sensor was plugged in with everything above I did

Something isn't set right if there is a catalyst fault. The rear simulator is there to prevent that.
You could always go in and disable the bit too though.

Regarding the O2 heater and sensor... double check the codes, sounds like you may have a front O2 code in there. All things being equal, if you have the rear O2 unplugged entirely it would only set the heater circuit, nothing else.

You need to know what the codes are before you try to figure it out though. Too many variables to guess at it.

I wouldn't buy anything until you see what codes are set exactly. No sense in buying a front sensor if the problem is your rear O2 patch. No sense in buying a rear one if your front O2 is bad.

Front o2 is good, im thinking its the rear for the heater since i dont have a cat anymore, i just bought a rear o2 sensor so ill plug it in restart the ecu and see where it takes me. Of not i can always return it im not installing it in the test pipe just plugging it in under the seat and keeping it from the floor board

Right-o.
Make sure you set it on something and don't leave the plastic cover on the sensor. That sucker gets real hot, it would be hard to explain melted plastic or carpet fuzz stuck to it
