The P2276 trouble code is having issues in bank 2 and sensor 3.
This means that bank two of the engine block, the bank that does not contain the number one cylinder is having issues.

When the mechanic is diagnosing the P2276 code, the first connect their OBD-II scanner to the onboard computer. They then gather information and data from the computer including the trouble codes that have been stored. They will then reset the codes and run the vehicle to see if they return. The codes return, they know they have an actual problem in that the code is not set by accident. The mechanics will then be able to begin the proper diagnosis of the vehicle and then make repairs.
In the case when there are lean or rich engine conditions that are providing incorrect readings, some technicians may mistakenly replace oxygen sensors. Other times, when the O2 sensor is the problem, technicians may replace the wrong oxygen sensor.

The black smoke can be alarming, and they will likely notice that the engine is not running properly.
