GMC - Po050 & Po155 - Heated O2 Sensor Heater Control Circuit Bank 2

OEM Issues - Chevy TrailBlazer, TrailBlazer SS and GMC Envoy Forum - forums.trailvoy.com
2006 Envoy Denali, 5.3L 4WD

Had these two error codes pop up this wknd - called the dealer where I normally take it for repairs as I generally trust them. Told me labor cost depends on where the O2 sensor requiring repairs is. Could be in the mainfold, could be in the rear? (not really sure what he was saying exactly).

Anyways - difference in cost could be up to 4 hours labor - so - any idea if I can tell by the error code, where I would need to be replacing the part and judge what the cost will be before I show up?

Also, have noticed a good lag in hard acceleration when I really step down on the peddle, so assuming this was the problem. Just hoping its around $100, instead of $400 for the repair.
