P2554 OBD-II: Throttle/Fuel Inhibit Circuit Low
P2554 Severity
Should you fix P2554 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 P2554?
The Fuel Injector Control Module (FICM) monitors engine speed in relation to the power requested by the driver. If the engine speed gets higher than requested by the engine computer (PCM), the FICM will disable fuel going into the engine, causing the engine to shut off. Code P2554 will be stored. Additional codes may also be present and should be diagnosed and repaired first.
