Hey guys, so i just got done installing the new pcm, and I love it! The only problem is that i scanned the car and got 4 different DTC codes. Im pretty sure they all refer to the same sensor and i think that its the O2 sensor on the rear exhaust manifold. I need to either clear the codes or replace the sensor because i have smog coming up soon. If anyone has any advise or thinks that it might be a different sensor i really appreciate the help. Thanks in advance, and here are the codes:

P0053: HO2S heater resistance, Bank 1, Sensor 1

P0134: HO2S circuit insufficiant activity, Bank 1, Sensor 1

P0135: HO2S heater performance, Bank 1, Sensor 1

P0030: HO2S heater control circuit, Bank 1, Sensor 1

Thanks again i really appreciate the help. And BTW, the car is an 05 base model with 180 stat, hv3, CAI, plog, rear PEM, zzp downpipe w/ cat, and dual magnaflow.

All the codes are bank 1 sensor 1. that tells you its on the front. As far as the problem i think its a short circuit more than a bad o2 sensor. Check all the wiring from the front sensor

I would reconnect the PCM first and make sure that the connections are good since he said that he didn't get the code until installing the new pcm.

very true, and since those are electrical related it could just be a bad connection to the pcm

That's just for the heater circuit in the oxygen sensor in the rear manifold. I would bet that it is coincidental.
