It’s not necessarily a bad ICP sensor. It could be, or it could still be a wiring issue, or you may have a problem with the IPR. If it’s not starting with the ICP unplugged, you need to figure out why you’re no longer building oil pressure.
Yes, the ICP sensor is on the head, no real special tools needed, But If your refering to oil on the the IPR plug, it and the inside can get oily, if it’s giving you problems it can be cleaned, and maybe work great again.
Beside this, How do I know if my 7.3 ICP is bad?
– Rough or lugging idling.
– Surging.
– Missing.
– Bucking.
– Stalling, especially at a full stop.
Likewise, Can you clean ICP sensor?
Yes, the ICP sensor is on the head, no real special tools needed, But If your refering to oil on the the IPR plug, it and the inside can get oily, if it’s giving you problems it can be cleaned, and maybe work great again.
Also, Can you drive with ICP sensor unplugged?
Second, if the engine is in good shape with no problems, it will idle perfectly fine with the ICP sensor unplugged.
How do you know if your ICP sensor is bad?
– Starting issues. One of the first symptoms of a possible issue with the injector control pressure sensor is issues starting the engine. …
– Engine misfires and decrease in power, acceleration, and fuel economy. …
– Check Engine Light comes on.

What causes low ICP pressure?
A damaged IPR valve can cause the extremely low icp reading. A piece of debris made it past the screen in the HP oil resivor and thru the pump. I would recommend removing the oil cooler and insepct and clean the passage between the resivor and HP pump before I replaced the pump itself.
Does an ICP sensor cause no start?
What cause truck won’t start or run if plug icp sensor?… The PCM won’t allow the engine to start unless it sees a minimum ICP of 500 psi. Unplugging it fools the PCM into thinking pressure is around 700 ish and it allows the engine to start. Sounds like your ICP sensor is bad.

What is a IPR sensor?
The IPR (injection pressure regulator) valve is responsible for regulating oil pressure in the high pressure oil circuit.
What will a bad ICP sensor do?
Another symptom of a possible issue with the injector control pressure sensor is engine performance issues. A faulty sensor can throw off the fuel mixture and cause the engine to experience misfires, a loss in power and acceleration, a loss in fuel economy, and in some cases even stalling.
What does an ICP sensor do?
In a diesel engine, the ICP sensor works as a moderator of sorts that insures the engine is running at maximum efficiency. ICP stands for Injection Control Pressure. This means that the sensor provides feedback and indicates the needed and existing injection pressure in the injectors.
Will a bad IPR throw a code?
The IPR can fail, not throw any CEL, or appear to be fouled and your truck will not start or even develop any ICP of appreciable amount.
What does an IPR do?
The IPR is mounted in the high pressure pump and achieves injection control pressure regulation by discharging excess oil through a shuttle valve into the front cover and back to sump. The PCM controls the injection pressure regulator (IPR) by an internal ground switch (low side driver) internal to the PCM.
How do I know if my 7.3 IPR valve is bad?
– Poor, rough, or unstable Idle, especially when you let off the accelerator.
– Injectors surging when you accelerate.
– Stalling out.
– Crank no start.
– Loss of overall power.
What is a IPR sensor 7.3 Powerstroke?
The 7.3 IPR valve — Injection Pressure Regulator sensor — works together with the high pressure oil pump to “create” oil pressure. Based on signals from the ICP to the PCM, your 7.3 Powerstroke HPOP provides oil volume to the 7.3 IPR which in turn physically “plunges” and produces the psi — pressure.
Where is the injector control pressure sensor located?
Since the IC pressure sensor is typically located on the injector pump or fuel rail, you need to remove pressure from the fuel system before removing the sensor. With some vehicles, removing the fuel pump fuse may work. With others, you can disconnect the fuel pump cutoff switch.
Where is the ICP sensor located?
The ICP sensor is located on the driver side cylinder head towards the front of the engine near the high pressure oil pump. Remove the electrical connector from the ICP sensor by relieving the retaining clip and pulling upwards away from the sensor.
