DTC P1133

Is it possible to have this code P1133 deleted(turned off) with out missing up the engine performance or running. I get this CTC all the time, I delete it and it pops back on.

I'd rather swap the sensor, since that's telling you it's reading slow. That's a typical code for the front O2 when it's dying, or after getting clogged from leaded gas.

I have replaced 2 times I believe with AC Delco o2 sensors and the problem has been going on since I had my TOGs installed. I have checked the wire harness and concectors, they are all good.

Odd, maybe just do a quick physical check of the harness ends, maybe there's a weak connection in the extension, depending on how you went about that.

You have headers? I know with LS1's people who install long tubes get this code a lot, because of the increased distance of the sensor from the head. Essentially the sensors don't heat up (quickly) enough and that sets the code. I've had this happen multiple times with brand new O2 sensors.

I don't know if the sensor location on 3800 headers would be far enough to make a difference, but it's worth looking at if you're confident that the O2 sensor itself it not at fault.

that happened to me once i got my togs put on as well. went though an acdelco o2, a denso, i warrantied the denso about a year ago and have been fine since. i believe johnny mentioned a way to tune that out though... not sure, u'd have to ask him though

Ok cause I have replced the sensor 3-4 times and the same so I need to find another way to get this SES light off.

how many wire is the o2 sensor?

3 I believe

u can test to see if the sensor is heating by turning the key on engine off with the sensor out of the pipe and connected to the harness. it should be quite hot within one minute of having the key on. if not theres a heater or power/ground to heater problem. and to answer your original question you should be able to have the error reporting turned off for this code but it would be in your best interest to make sure there isnt an underlying issue
