The ICP (Injection Control Pressure) Sensor is responsible for controlling the IPR (Injector Pressure Regulator) Valve in the Ford 7.3 Powerstroke. A faulty ICP Sensor can cause all kinds of problems. Poor idle, stalling, surging, or not even allowing the engine to start at all.
Can you drive with ICP sensor unplugged?
You can drive as long as you like. You may notice a small reduction in mileage but its nothing major. When the ICP is unplugged the PCM defaults to a generic table. Mileage and throttle response is affected, but like Peter said, it’s not going to hurt anything.
What does the ICP valve do?
Injection control pressure sensors (ICP sensors), or pressure valves, control the amount of fuel you release when asked by the engine in the appropriate environment at all times. The sensors provide vital information about your current performance to the engine, with a particular emphasis put on the amount of fuel.
What does ICP stand for diesel?
The injector control pressure (ICP) sensor is on both the 7.3L and 6.0L Powerstroke engines. They use a high pressure oil system as a way to pressurize fuel in the injector body. ICP sensors on the Ford 7.3 diesel engines read the oil pressure in the HPOS.
Can a ICP sensor cause a misfire?
What Will A Bad Icp Sensor Do? In some cases, a faulty sensor can cause the engine to misfire, lose power and acceleration, lose fuel economy, and even stall. It is also possible for similar symptoms to arise from other issues, so a proper diagnosis is required.
Can you clean a 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. It is definitely worth a try first.
What should the injector control pressure be on a 6.0 Powerstroke?
Verify ICP & IPR valve function – A minimum 500 psi injector control pressure is necessary to start the 6.0L Power Stroke diesel. If oil pressure does not reach or drops below 500 psi an injector will not fire. ICP typically reaches anywhere between 800 and 2,000 psi while cranking.
Where is the ICP on a 6.0 Powerstroke?
On 2003 and early 2004 model year 6.0L Power Stroke engines, the ICP sensor is located behind the turbocharger and beneath the turbocharger up-pipe collector (turbine inlet), fastened through the high pressure oil pump (HPOP) cover next to the IPR valve.
Does the IPR control the ICP?
The IPR is a by-pass valve that controls the high oil pressure depending on demand. The ICP monitors the oil pressure in the LH head.
What does an IPR sensor do?
What Does A Ipr Sensor Do? It regulates the engine pressure by controlling how far the Oil Pressure Oil Pump (HPOP) goes. When the oil is pushed into the High Pressure Oil Pump, a valve in the High Pressure Oil Pump (HPOP) is released.
What is a good ICP reading?
In the horizontal position, the normal ICP in healthy adult subjects was reported to be within the range of 7–15 mm Hg. In the vertical position it is negative with a mean of around −10 mm Hg, but not exceeding −15 mm Hg. The definition of raised ICP depends on the specific pathology.
What is ICP voltage?
The specified excitation voltage for all standard ICP® sensors and amplifiers is generally within the range of 18 to 30 volts.
What should IPR read at idle?
At warm idle you should be 600-650 icp and 8-10% Ipr. The Ipr % can be higher when cold.
What is injector control pressure?
The injector control pressure sensor is an engine management component that is commonly found on diesel engines. As its name implies, it is an electronic sensor that monitors the fuel pressure going to the injectors.
What does the IPR sensor do on a 6.0 Powerstroke?
The IPR (injection pressure regulator) valve is responsible for regulating oil pressure in the high pressure oil circuit. Recall that the 6.0L Power Stroke, like its predecessor, relies on an electronically controlled hydraulic injection system in lieu of a high pressure injection pump.
