After installing my TTS Headers I am getting the following codes.
10-PCM P1133 H C
10-PCM P1153 H C
BO-FRA U1064 H

I have cleared them twice.

P1133 Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 1 Sensor 1

P1153 Heated Oxygen Sensor (HO2S) Insufficient Switching Bank 2 Sensor 1

U1064 Loss of Communication with BCM

The C5 computer transmits the following diagnostics: Powertrain Control Module (PCM) and Remote Function Actuation (RFA).


Hope this helps, Tom.

U1064 is normal when battery is disconnected, the other 2 codes I would check to see that they plugged the connectors back in when they did the work, the last person that had these codes on another Forum had the wires not plugged back into the O2 sensors.

Thanks guys.
Pulled a 354.0 rwhp 348.0 rwtq (SAE)today.
My computer left for CA today to be programmed for my mods.
I'm hoping for another 10-12.
More at 11. /phpBB/images/smiles/icon_smile.gif

I know this will sound crazy, but a guy I met @ E-town had codes for the sensors like yours and when he installed the headers, removal of the ox sensor was easy, but he didn't reinstall them with the special GM anti-seize and he would get code problems. He replaced the ox sensors and the factory replacements come with the anti-seize already applied and his codes cleared with no more problems. This is the only time I have heard of this, but you can bet when I had mine installed I took a can of the anti-seize to my installer and he laughed because he already had the product.
