P2248

DTC P2248, sometimes indicated as P224800 is an OBD diagnostic trouble code indicating a manufacturer-specific fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing o2 sensor reference voltage performance bank 2 sensor 1.

The O2 Sensor Reference Voltage Performance DTC (diagnostic trouble code) is set when the engine's computer detects that the voltage from the oxygen sensor is not within the correct range. This may be caused by a faulty oxygen sensor, a wiring problem, or a problem with the engine's computer.
If this DTC is set, the best way to fix it is to find and fix the underlying problem. This may require checking the oxygen sensor, the wiring, and the engine's computer. If any of these components are found to be faulty, they should be replaced.
