P2624 OBD-II: Injector Control Pressure Regulator Circuit Low

P2624 Severity

Urgent

Should you fix P2624 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 P2624?

The Injector Control Pressure Regulator (IPR) controls the oil pressure out of the high pressure oil pump. This pressure is used to control the fuel injectors. If the oil pressure is too low, the injectors will not operate correctly. The engine computer (PCM) monitors fuel pressure when the engine is running. If the oil pressure regulator sends back an implausible signal, code P2624 will be stored.
