HELP interpret these codes!
HELP interpret these codes! Ok so i'm newbe when it comes to electronic/diagnostic stuff, anyways my car started throwing codes a while ago, finally got around to getting them scanned, here are the results:
P0135 HO2S Heater Circuit Bank 1 Sensor 1
P0155 Heated Oxygen Sensor Heater Circuit (bank 2, sensor 1)
P0160 HO2S Circuit Insufficient Activity Bank 2 Sensor 2
P0161 HO2S Heater Circuit Bank 2 Sensor 2
P0410 Secondary Air Injection System
The guy scanning them wasn't much help, but I assume my O2 sensors are going out? How many O2 sensors are on the LS1? It should just be 4 right?
My friend and I installed LT headers on my car a few yrs ago and the rear O2's have been tied up out of the way and TSP turned off rear O2's for me.
Any help would be appreciated. TIA!

Looks like you'll need to take care of the Air system with some tuning. That usually comes with installing a race header with no provisions for it.
The rest of it looks like what you thought it was... The front o2s going out.
I suggest replacing them with the Bosch Corvette Rear o2s (13111). They heat up a bit quicker and seem to be better than a factory Fbody unit. Not to mention you won't have to get extensions since they're long enough to start off.

So you think that both of the front O2's are defective? Is this normal on a car with only 44k miles and with my mods?
The AIR and EGR stuff was all removed back when the headers were put on. These codes only started to appear recently. How come the code for the AIR system wasn't thrown years ago when it was removed.
Thanks

A guy here in town has seen about the last 5 cam swapped LS1s need new o2s almost as soon as they're back on the road.
Not sure why it would start throwing the AIR codes if it was all removed. Hopefully someone with some more experience could lead you in the right direction.
