Apr 11, 2020 · A bad HPOP will often times cause a repetitive fluctuation in the pressure of the High-Pressure oil (ICP pressure reading). To detect this, you need to be confident that your ICP sensor is reading/working properly and does not have any wiring issues.

Mar 11, 2006 · While checking for codes again today my local Ford tech told me that the HPOP is running 600psi at idle and about 1200psi at 3000 rpm. Does that sound right for a stock early 99 pump with 435,000 miles on it? Is it time to replace it?

Mar 24, 2010 · There is a sensor on the high pressure oil rail that measures the oil pressure, you might be able to find a way to tee of that to read the pressure with a mechanical gauge. Otherwise, you'd have to get a computer scanner to read the oil pressure as the engine's computer sees it.

Apr 6, 2024 · A bad HPOP will often times cause a repetitive fluctuation in the pressure of the High-Pressure oil (ICP pressure reading). To detect this, you need to be confident that your ICP sensor is reading/working properly and does not have any wiring issues.

Jan 1, 2022 · High-Pressure Oil Pump (HPOP) – This is a cam gear driven pump that is supplied with oil from a reservoir on the top of the engine block. The reservoir, which is shared with the OEM oil cooler, is used to keep a constant supply of oil available for the HP oil system.

Oct 4, 2022 · By maintaining 2800+ psi, your HPOP is exceptional and can handle any injector 250cc and under. Find out if you need a new HPOP with a mechanical gauge or using a scantool. Discover the efficiency of your HPOP using these two procedures.

Jun 1, 2017 · by plugging the icp sensor directly to the hose you can use your scanner to watch ipc pressure. you plug your icp connector into the sensor then see what value you get. By doing it this way you're taking the injectors and other components …

Aug 16, 2017 · It is controlled by the injection pressure regulator (IPR), the injection control pressure (ICP) sensor and the strategy in the powertrain control module (PCM). The IPR is a pulse-width modulated valve operating at 400 Hz.

Jun 18, 2008 · I have done over 10 WOT runs and my hpop only fluctuated once from 28/2900 psi down to 2500 psi and that shouldn't affect fuel atomization at idle or on start up since I'm maintaining steady idle ICP at 7-800 psi.

The symptoms of a 7.3 high pressure oil pump are an oil warning light on the dashboard accompanied by a whining noise from the engine bay. Blue smoke from the exhaust, unusually long crank times, and losses of power at high RPMs …
