Code P2240 Ford Description
The P2240 code for Ford vehicles indicates a problem with the Oxygen Sensor Positive Current Control Circuit on Bank 2 Sensor 1. This sensor is responsible for monitoring the oxygen levels in the exhaust gases and providing feedback to the engine control module to optimize fuel mixture for efficient combustion. When the circuit is open, it means that there is a break or disconnect in the wiring, preventing the sensor from sending accurate information to the ECM. This can lead to poor engine performance, reduced fuel efficiency, and increased emissions. If left unaddressed, it can cause further damage to the catalytic converter and other engine components.
Common Causes of P2240 Ford
- Faulty oxygen sensor
- Wiring issues or loose connections
- Corrosion or damage to sensor connector
- ECM failure
- Exhaust leaks near the sensor
