P2245

DTC P2245, sometimes indicated as P224500 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 circuit low bank 1 sensor 1.

The O2 Sensor Voltage Circuit Low is a problem with the reference voltage to the O2 sensor. It could be a wiring problem, a bad sensor, or a problem with the computer.
One common solution is to clean the sensor with a sensor cleaner. If the problem persists, the sensor may need to be replaced. If the wiring is the problem, it may need to be fixed or replaced. If the computer is the problem, it may need to be replaced.
