Po 155 I believe this is one of the rear 02 sensors that is throwing this code. This is correct right?
My question is, my car throws this code and 135 (same code I believe) once or twice a year; is it worth it to buy the corvette bosch sensors or put up with the SES light for a few days till it eventually turns off?
I've also been told that with LTs (which I have) the 02s will throw this code occassionally with cold weather or abrupt weather changes from hot to an all of a sudden cold. This kinda seems to be when it throws the code. Is this true?

Here's a list of all of them...

This is indeed for the front O2 sensors, LT related. The Bosch O2's would help, and probably prevent it, but I'd just live with it unless you're dieing to drop $110.
Here's a link to them for cheap if you ever decide to swap.
