Will a bad oxygen sensor always throw a code? Vehicle is a 91 Chevrolet K1500. 4.3 liter V6. It has only one sensor that is upstream of the catalytic converter.
But those bad ol’ bead beds were gone by 1981 and GM went to monolithic converters like everyone else, right? Actually, no. While they did begin phasing in monolithic converters in the early-mid 1980s, GM kept putting pellet-bed type converters in trucks and vans clear on up through the mid-1990s

Bosch 02 sensors seem to die quicker than the denso or ngk ones.I'm going to proactively replace my elantra's 02 sensor, as mileage seems to have dropped a bit.
Rock auto has 2 sensors from bosch
Bosch 17270 as an upstream
Bosch 17319 as a downstream or upstream with calif emissions.

My car is not calif emissions, but what would be the difference in them? I would think most of the calif emissions difference would be in the ECM programming.
The 02 sensor just gives data to the ecm, what would be different?
@Trav, @The Critic what do you think ?
