Ok I'm getting code...P1133 (bank one 02 sensor or whatever)...

96 Z28SS, I have the driver side cat gutted and i have 02 sims for the back. When it says "bank 1", is that referring to the sensors screwed into the manifolds? If so, which manifold is it, or can you not tell from that code which side it is?

Thanks

 

P1133 Heated Oxygen Sensor (HO2S) insufficient switching Bank 1 sensor 1


thats the drivers side front 02 sensor. it;s working but slow to respond. Usualy a sign of a failing 02

 

Yes, I just had that code (P1133) and also the same code for the passenger side (P1153)

I ordered 2 O2 sensors from www.gmpartsdirect.com and it fixed my problem.

I think it's about $42 shipped for one O2 sensor from them.

Shoebox has the partnumber on his website.
