The ECM has detected that fuel pressure is higher than the commanded pressure. Engine power is reduced. Circuit Description: The electronic control module ECM monitors engine operating conditions, including the reading of rail fuel pressure, and changes the flow command to either increase open the fuel pump actuator or decrease close the fuel pump actuator the fuel supply to the high-pressure pump.

Component Location: The fuel pump actuator is installed in the adapter on the back of the high-pressure fuel pump. Conditions for Running the Diagnostics: This diagnostic runs continuously when the engine is running. Conditions for Setting the Fault Codes: The ECM has detected that the fuel rail pressure reading has exceeded the recommended operating limits.

This will normally occur at key-off. If necessary, recalibrate the ECM. A fuel pump actuator with excessive leakage or a damaged inboard o-ring will result in high fuel rail pressures at idle or light load. If the fuel pump actuator exhibits excessive leakage, it is possible that the fuel rail pressure will reach the opening pressure of the fuel rail pressure relief valve and Fault Code can possibly also become active.

When checking the fuel rail pressure sensor accuracy, make sure the high-pressure fuel rail is not pressurized. The fuel pump, high-pressure fuel lines, and fuel rail contain very highpressure fuel.

Do not loosen any fittings while the engine is running. Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level. There could be a significant amount of time waiting on the rail to depressurize to zero on some engines. In such cases, it may be necessary to manually relieve the pressure from the high-pressure fuel rail.

Temperature of the engine electronic control unit. Differential crankcase blow-by pressure as measured through a tube with a venturi. SPN is not to be used — obsolete. The position of the exhaust gas recirculation valve expressed as a percentage of full travel. Zero percent means the valve is closed and no exhaust gas is flowing into the intake air stream.

One hundred percent means the valve is fully opened. This parameter is intended for the third accelerator control in an application. If an application has only one accelerator control, use SPN This parameter is intended for secondary accelerator control in an application. Ratio of volume of fuel to the total volume of fuel in the second or right-side storage container.

Exhaust pressure as a result of particle accumulation on filter media placed in the exhaust stream.

It is recommended that SPN be used as it has better resolution. Gage pressure of air in an engine starting system that utilizes compressed air to provide the force required to rotate the crankshaft. Value of set chosen velocity of velocity control system.

See SPN for an alternate resolution. If an algorithm that can modify the cruise control set point exists in the system, such as Predictive Cruise Control or Adaptive Cruise Control, then Cruise Control Set Speed SPN 86 will not include the speed adjustment made by that algorithm. For the parameter that includes the adjustment, see Cruise Control Speed SPN for the final speed used by the cruise control algorithm.

This alone can free up tons of hard drive space. For example, I have lots of old photos and videos from college and high school. When I want to access them, I can simply log in to Dropbox from anywhere, or use the app on my iPhone or iPad. On the Mac, you can dictate what folders sync from Dropbox and are stored locally on your Mac. By default, anything you put in Dropbox will be stored locally.

You can access selective sync settings by choosing Preferences and then hitting the Accounts button. As you can see in the photo above, I have my photo backup disabled from Dropbox on my Mac. My only advice would be to make sure you have a complete backup of your photo library before enabling iCloud Photo Library.

I ended up with a lot of duplicates and some folks have reported albums going missing. That being said, there are millions of happy iCloud Photo Library users out there. Just be sure to prepare, in the event that something does go awry. To enable it, just launch the Photos app on your Mac, choose Photos in the top navigation and then Preferences.

Under the iCloud section, simply check the box for iCloud Photo Library. Then just make sure the sub-option for Optimize Mac Storage is also selected. Hat tip to Eric in the comments who pointed out that remembering to empty your trash periodically is important. This post was syndicated via The App Factor. There are no disks in SSDs. You may only re-download an app from the Mac App Store so long as that app is still sold in the Mac App Store.

This is one of the things that irritates me most. If I purchase it, it should be available in the cloud forever. Kind of hard to save storage space if you have to worry about a movie being removed from the Store. None of my computers or iOS devices have used hard drives for years.
