Code P2248 Ford Description
The P2248 diagnostic trouble code (DTC) for Ford vehicles indicates an issue with the O2 sensor reference voltage performance in Bank 2 Sensor 1. This sensor is responsible for measuring the oxygen content in the exhaust gases and providing feedback to the engine control module (ECM) to adjust the air-fuel mixture for optimal combustion. The reference voltage performance refers to the voltage signal that the sensor produces, which helps the ECM determine the oxygen level in the exhaust.
Common Causes of P2248 Ford
- Faulty O2 sensor
- Wiring issues (short or open circuit)
- ECM malfunction
- Exhaust leaks
- Contamination of the O2 sensor
Symptoms of P2248 Ford
