I ask because you may have fixed the failure but not the cause of the failure

First off the voltage does no read .9 all the time it changes based on how much throttle/fuel you give it. Didn't say it was GM's fault simply said got the short straw no biggie bought the new one replaced. No issues fuel trims and AFR's look great.
