doing the heater calibrating outside the pipes will alter the time it takes for the sensor to reach temps compared to when installed, so it can mess up the readings and throw an error 8.

otherwise, error 8 codes almost always happen if the sensor is installed too close to the turbo without a heatsink. Where is yours located and has the setup changed recently?
I'm not sure how the heater calibration would have gotten reset. It says it only resets heater calibration if the sensor is not connected to the controller and the controller is operated for more than five seconds. The sensor has never been disconnected from the controller during anything I have done.

The first time calibration instructions has the sensor outside of the exhaust for both the sensor calibration and the heater calibration, it specifically says to keep the sensor outside of the exhaust for first time calibration so I'm not sure how it makes a difference if the sensor is out or in for heater calibration. Free air temp and cold exhaust temp will likely be exactly the same.

No setup change. It's downstream, right before the cat location.

I think the sensor just **** the bed. I could try and disconnect it and operate the controller to reset everything and then reconnect and do the first time calibration just to be completely sure, but I'm thinking the sensor is done.

Matt at DIY seems to think new sensor is necessary, but then again he may want to sell me a new sensor. I try not to be too cynical.

With a little searching/blowing one of the parts guys at orielly's you can usually pick up the sensor for less than $40 bucks.

Here's the bosch part number, plug and play. #17014

I probably should have just bought it off Amazon.

But the DIY guys help me out so much that I don't mind buying it from them.

Or at least that is my excuse since I ended up buying it from them already before looking for alternatives.

$46.99 from Advance Auto Parts after discount code A124. Might be better codes floating around.

They change the actual code every 6 months or so, but there is almost always a 30% off code to be found by just googling "advance 30% code". Usually it's hiding on those crazy coupon lady sites.

Ask me how I know...
