I have had some issues with codes P1153 and 1133. I have a new catalytic converter all new sensors, a new gas tank and all new injectors. The light is back on with the same codes. Any ideas?
Thanks in advance!

P1133 = Heated Oxygen Sensor (HO2S) insufficient switching bank 1 sensor 1 (Rear Bank)
P1153 = Heated Oxygen Sensor (HO2S) insufficient switching bank 2 sensor 1 (Front Bank)

What mods do you have? LT headers?

Yes. I know what the codes are but no repairs keep them from reoccurring. No modifications. Everything is factory. I don't know about the headers? Is that a possible original install? If so, how do I determine if long or short?
Thanks!

I was posting the trouble codes description to show others when they stumble upon this thread during searches.

Long Tube headers are only aftermarket. From factory TBSS comes with shorty cast iron exhaust manifolds. Visually inspect/check the O2 sensor wiring and connectors for any broken or bent pins. Check for corrosion too.

Thank you, scott750! I have asked the repair facility to do this. They are having a hard time finding the problem. :(

I took it to a different repair shop and they replaced the ecm. Another pricey repair but I figured just one more. It drove very well for a few weeks then the check engine light came on again. The OBD displayed 2 codes about stuck lean and one of the sensors. It went off within a day and has not come back. Fingers crossed!

Here we are 2 months later and she is definitely back! Riding like a dream thanks to the new mechanic.
That's great news! Glad you got it all worked out.
