P2150 OBD-II: Fuel Injector Group "B" Supply Voltage Circuit Low
P2150 Severity
Should you fix P2150 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.

If the PCM detects one or both of the fuel injectors in that group are not functioning properly, the PCM will set code P2150. The two injectors in that group will be disabled to prevent damage to additional components.
