P2255: Your Car’s Oxygen Sensor Needs Attention
The P2255 code refers to the O2 Sensor Negative Current Control Circuit Low 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
If you see the engine light on or the service engine soon warning light, it could be due to the P2255 fault code. This code is caused by a faulty front oxygen sensor bank 2, an open or shorted front oxygen sensor bank 2 harness, or a poor electrical connection in the front oxygen sensor bank 2 circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
If you’re experiencing an Engine Light ON (or Service Engine Soon Warning Light) due to a faulty Front Oxygen Sensor Bank 2, you can visually inspect the related wiring harness and connectors to fix the issue. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. This will help you identify if the Front Oxygen Sensor Bank 2 harness is open or shorted, or if there is a poor electrical connection in the Front Oxygen Sensor Bank 2 circuit.
If you find damaged components or broken, bent, pushed out, or corroded connector’s pins during the inspection for the P2255 fault code, you should replace or repair them as necessary. This will ensure that the Front Oxygen Sensor Bank 2 is receiving the proper electrical connection and prevent any further issues with the engine light or service engine soon warning light. Be sure to visually inspect the related wiring harness and connectors to ensure that everything is in good condition.
Wrap Up
If your engine light is on and showing the P2255 code, it could be due to a faulty front oxygen sensor bank 2, an open or shorted harness, or poor electrical connection. To fix it, visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
