Have you replaced sensor 3 in the car yet? It seems like that is the one that causes problems. Sensors 1 and 2 seem to be less of an issue. I replaced Sensor 1 with a Bosch and there have been no issues with it, for example. Sensor 3 is teh one that appears to be finicky. If I get a code again my next step is to check the exhaust seals. If they are fine I will swap sensor 2 (appears to still be OE) with sensor 3 and see if the problem follows the sensor.
If the exhaust is leaky, we will change the seal and see if the code goes away. If it does, that was the issue. If the exhaust is tight and the code goes away after the swap, I have to conclude the problem is with using Bosch for sensor 3. If the prolem follows the sensor then I will conclude it was a bad sensor out of the box.
