My engine light is on & I've had the car scanned by a few different ppl & each time it's scanned this comes up; "Code 1133, No input to bank one O2 sensor" I've replaced both O2 sensors & checked the wiring for any damage. Unless its by some chance a malfunctioning O2 sensor I'm at a complete loss whats causing this. I need to get this fixed it causes my car to run lean & sluggish. Has anyone delt with this problem & know what I should do?

Sounds like your pacesetters are leaking. Do you have the y-pipe welded? I got the same code a year ago.

Yep, my y-pipe is welded. So the code went away after you got your y-pipe welded?

Yea, I was having issues with the Y-pipe at the time. Is that the only code you are throwing? I threw like 3 codes...Originally Posted by SDGTP99

Do you still have an EGR? if so, make sure your not leaking there either.

It is the only code I am throwing. I checked under the exhaust & the y-pipe isn't welded all the way around. It leaked a bit on the topside so I just wrapped heat tap around it as a temporary stop gap. No leak for now.
I don't have an EGR & nvr threw a code for it. Probably something to do with the ZZP PCM.

Trace your wires on the o2 sensor again (no breaks or burns), and maybe put some dielectric grease (to ensure good connection on the plug).
I went through like 3-4 o2 sensors troubleshooting that on mine.

I'll trace the wires again. Have thought about replacing the extension wire & the O2 sensor to see if that fixes the problem. Hadnt thought about using dielectric grease I'll try that too.

what brand O2 sensor? I made the mistake of using a bosch the first time around and wound up with the same code and warrantied the sensor twice before i tried an ac delco from rock auto. havent seen the code since

^^^Both O2 sensors on my car are Bosch. I had my exhaust leaks welded shut & the code is still on. I ordered a Denso front sensor today to replace the front Bosch sensor. This had btr fix my problem.If it does not I may be forced to buy a new PCM.

just delete the code. I had to. Its a common code when you do headers, its the switch rate on the 02 sensor

Code always comes back within a day or two after being deleted. If the code is still there after i install the denso sensor im going to asume it is my zzp pcm. Maybe i didnt get my egr code deleted or something...
