Code P2255 Lincoln Description
The P2255 diagnostic trouble code (DTC) for Lincoln vehicles specifically refers to the O2 sensor negative current control circuit low in Bank 2 Sensor 1. This code indicates a potential issue with the oxygen sensor located in the exhaust system of the vehicle. The oxygen sensor plays a crucial role in monitoring the amount of oxygen in the exhaust gases and sending this information to the engine control module (ECM) for proper air-fuel mixture adjustment.
Common Causes of P2255 Lincoln
- Faulty O2 sensor
- Corroded or damaged wiring/connectors
- Issues with the ECM
- Exhaust leaks
- Engine running rich or lean conditions
Symptoms of P2255 Lincoln
- Decreased fuel efficiency
- Engine misfires
- Rough idling
- Illuminated check engine light
- Increased emissions
