What should IPR be when cranking?

You should see 0.2 – 0.25 volts Key On Engine Off (KOEO), and when you start cranking the voltage should climb up to around 4.5 volts if the engine doesn’t start. The IPR will start at 15 percent KOEO, and start climbing up to 85 percent on a long crank. Last but not least is the Sync and FICM sync PIDs.

What is IPR and ICP?

The IPR valve and ICP sensor work together as part of a feedback cycle to control the oil pressure to the injectors in the HEUI fuel system. The ICP reports the actual pressure to the PCM which then makes an adjustment in the position of the IPR valve to bring actual pressure into sync with desired pressure.

What does ICP stand for Ford?

Injection control pressure sensor
The ICP sensor or Injection control pressure sensor is found on Ford’s Powerstroke 7.3 L diesel engines.

What are the symptoms of a bad Ficm on a 6.0 Powerstroke?

What a Failing FICM Looks and Sounds Like. When you aren’t getting 48-volts to the injector coils you get: hard starts, rough idle, loss of power, poor drivability, and excessive smoke out the tailpipeā€”and in cold weather each of those symptoms will be amplified.

What is a HPOP on a 6.0 PowerStroke?

Late Model 6.0L HPOP The HPOP provides oil volume for the fuel injectors to use and its accompanying injection pressure regulator (IPR), which controls HPOP outlet pressure and is located in the HPOP cover, pressurizes this oil as high as 3,600 psi in stock form.

What does ICP sensor do?

The ICP sensor or Injection control pressure sensor is found on Ford’s Powerstroke 7.3 L diesel engines. The ICP sensor is responsible for monitoring oil pressure being passed on to the PCM to pressurized fuel injectors using the IPR (Injection Pressure Regulator) for proper vehicle operation.

Will a bad ICP sensor cause a no start?

Injector Control Pressure Sensor: When an ICP is failing, the engine runs extremely rough as load is imposed (under throttle), and the condition can eventually contribute to a 7.3L’s inability to start. If the engine runs smoothly with the connector unplugged, the ICP is bad.
