Q: What does code P2415 mean?

O2 Sensor Exhaust Sample Error (Bank 2 Sensor 1). P2415 indicates that the powertrain control module has detected an invalid or implausible exhaust sample from the upstream oxygen sensor on bank 2, which monitors the cylinder bank that does not contain cylinder number one. The computer compares the sensor's switching activity against expected values and flags the sample as erroneous when the signal fails to respond correctly to exhaust changes.
