What the P2271 code means. This code indicates the downstream O2 (oxygen sensor) on bank 1 has failed an onboard test run by the PCM (powertrain control module). Bank 1 is the set of cylinders that includes the number one cylinder.
What does it mean when your O2 sensor is stuck rich?
This code indicates there is too much fuel in the exhaust measured by bank 1 sensor 1. Bank 1 is the bank of cylinders that contains the number one cylinder.
What is a P2271 code?
OBD-II Code P2271 is defined as a O2 Sensor Signal Biased/Stuck Rich. The oxygen sensor measures the amount of oxygen in the exhaust between the engine and the catalytic converter. This sensor is supposed to fluctuate a minimum of 10 times per second within a specified voltage.
