P268B OBD-II: High Pressure Fuel Pump Calibration not Learned/Programmed
P268B Severity
Should you fix P268B yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P268B?
The high pressure fuel pump converts low pressure fuel from the tank to high pressure fuel for the fuel injectors. If the pump is not programmed to the engine computer (PCM), code P268B will be stored.
