need help with two codes, please the car is a 2000 camaro z28. i have put on full custom exhaust with long tube headers. i have been fighting two codes, i did have more but i replaced one of the o2 sensors. i have a diablo sport tuner that reads the codes and resets them. every time i reset them, the next time the engine runs a cycle it throws the same codes... here they are according to the tuner.
P0161 O2S heater circuit, Bank 2- sensor 2 malfunction.
P1153 HO2S Bank 2 sensor 1. insufficient switching.
if someone could tell me what these codes mean, and how to fix them i would be forever greatfull. my state has passed an emissions test to take and i cant pass it with this going on. thank you for any comments that you could give me!

Verdad Gallardo I was thinking, since you have a P1153 bank 2 sensor 1 , well that code usually means that the sensor is bad. Since that one is in front it could cause the rear one to malfunction, just like the code says. i would replace the front on the bank 2 and i bet it will take care of the problem
The p0161 rear o2 bank 2 heater is bad, as long as the wires are ok. Most likely they are, heaters go bad often. The p1153 front 02 bank 2 sounds like it's lazy. You should relace it also. I like to use factory parts but you said you repaced the other front sensor already with a bosh? If you haven't had any codes pop up for that sensor you might want to put a bosh on the other side aswell.
All 4 of mine went bad after I put my longs on. One at a time. Good luck.

well i put two new O2 sensers in bank one and two, and erased the codes with my diablo, and it seems to have done the trick. i took it today to get the emissions test done and it passed with flying colors. i just wanna say thanks for all the help and hopefully i can get it tuned now
