P2254: Oxygen Sensor Circuit – Bank 2 Sensor 1
The P2254 code refers to the O2 Sensor Negative Current Control Circuit Open Bank 2 Sensor 1. This sensor is located in the exhaust manifold and detects the amount of oxygen in the exhaust gas compared to the outside air. The heated oxygen sensor 1 generates voltage from approximately 1V in richer conditions to 0V in leaner conditions.
The signal is sent to the Engine Control Module (ECM) which adjusts the injection pulse duration to achieve the ideal air-fuel ratio.
The ideal air-fuel ratio occurs near the radical change from 1V to 0V.
FAQ
