By unplugging the sensor, you remove ICP input to the PCM, and the PCM substitutes a “best guess” scenario for pressures. So if guessing makes the truck run better, then your ICP sensor isn’t working correctly.
Can you unplug ICP sensor 6.0?
The way the 6.0L calibration has worked is that by diconnecting sensors the pcm will go into a “default mode” for that system. If you unplug the icp, the pcm has no back feed at all so it sets the ipr and icp at a preset value and as long as the system can produce the desired pressure, it will start and run.
Can I drive with ICP 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.
Does an ICP sensor cause 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. Oil contamination in the wiring usually is the cause.
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.
What is ICP on a diesel?
Description. 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.
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.
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.
Will a 7.3 ICP start unplugged?
yes you can run the 7.3L w/o the ICP sensor plugged in though you’ll be staring at the SES/CELight constantly
