Long tubes ses light.. p1133.. I put corvette o2 sensors on the camaro with the long tubes and had the car tuned but the light is back on?? Any idea's if the tuner would tune two of the four out and leave the other two.. I thought i had this light licked with the tune.. ???
oh btw i asked for them to tune em out when i had it tuned..

well im guessing that the tuner can only tune out the two that send the messages to the pcm about the cats.. So that would mean that the other two are still in the system.. I dunno.. I do know that you can get the cat's sensors tuned out does anyone know if the p1133 code is for the header o2's or the cat's o2???

All four o2's send signals back to the PCM, the tune probably deleted the rear o2's but the front ones still need to read.
As far as the codes I'm not really sure, I did the PCM pin swap when I put my long tubes on it went without a hitch. No cutting, splicing, extensions, or corvette sensors.

It's just where you swap the pins going to the PCM so the rear 02 harness acts as the front. Because you have to use the front 02's, I know some people just try to use the rear harness without doing the pin and that won't work.
Just a suggestion a lot of people don't know or talk about it much but I think it's great.

There is a link to the original post about it, you can also google PCM Pinout do you can get a chart of which wires go where.
Just my 2 cents ain't worth much.... I know.
