Ambient — This is the air temperature that the engine will be ingesting. BAP Barometric air pressure sensor. This was eliminated in later models. This data is now inferred from the MAF readings. Boost This is simply a measurement of pressure in pounds per square inch. It applies to a blown car and is normally measured in the intake manifold. An engine is a big air pump. The more airflow it can generate, the more power the engine will make. CCS Converter Clutch Solenoid used in an automatic transmission to control lockup of the clutch that is inside the torque converter.
This a light that comes on when there is an emissions failure or a sensor failure. If this light comes on, then a diagnostic trouble code has been set and action needs to be taken to resolve this issue. Closed Loop When the engine is using input from the oxygen sensors and the MAF to control the engine to This type of ignition system has no distributor but only has a small number of magnets on the crankshaft, exactly half the number of cylinders the engine has.
This system needs a camshaft sensor to properly synchronize the ignition system. This type of system was mainly used on 3. This is a crucial sensor that measures and reports to the PCM the actual engine coolant temperature in the engine.
This is an ignition system used in Ford vehicles that do NOT use a distributor. This type of ignition system uses a tooth wheel on the crankshaft to pickup engine speed. This sensor provides feedback as to whether or not the system is either rich of It does not, and cannot provide data as to the actual air-fuel ratio.
This reduces combustion temperatures and at the same time reduces nitrogen based emissions from the vehicle. It is only used at part throttle on a warm engine. The EGR valve does not hurt performance at all and even increases fuel economy. EGT Exhaust gas temperature. This is a solenoid in an automatic transmission that regulates line pressure. This can also be referred to as a TV solenoid. This valve uses feedback from the PCM to automatically vary the amount of air going into the engine at idle to control idle speeds as set by the PCM.
This can also be referred to as an ISC valve. Typically, a longer runner makes more low RPM torque and a shorter runner makes more peak horsepower HP. Having two runner lengths allows a broader, flatter torque curve. Normally, the longer runner creates more swirl in the combustion chamber and therefore the combustion chamber becomes a faster burn chamber, requiring less overall timing for peak HP.
When the IMRC opens the shorter runner is utilized. This results in a slower burn rate combustion chamber and requires more timing to produce peak HP. This area is kept powered up even when the vehicle is not running. Load Load can also be called volumetric efficiency. Load or volumetric efficiency is actually the measurement of how much air is flowing into the engine. If it only sucks in 2. Load is VERY important because as you will learn, load is used on many of the tables for a variety of critical engine controls.
Load is calculated in the PCM based on input from the mass air meter. This is the most critical sensor in a car. It directly measures airflow with an electronic hot wire sensor.
The sample tube size is calculated to be a certain proportion of the larger inlet tube. The wire is heated to a specific temperature and the PCM tries to keep it at a certain target temperature. The meter can output up to 10 volts or more, but the PCM will only acknowledge a maximum of 5v. As engine airflow increases, the voltage increases signaling more air to the PCM. If the meter is of insufficient capacity and goes past 5v, this is called pegging or saturating the meter.
We will discuss this in detail later. This is called the MAF transfer function. The transfer function is a series of points on a graph that shows a specific air weight at 30 voltage points. There is a lengthy discussion of this in this book. This measures the pressure inside the intake manifold. This is a sensor on an automatic transmission that tells the PCM what position the gearshift lever is in.
NA This means naturally aspirated. A power adder nitrous or blower is not being used. O2 Oxygen. Open Loop When the engine is running without direct input from the oxygen sensors. This sensor is located either in the distributor if so equipped with one or is calculated from a crankshaft position sensor. Power Adder — Either a supercharger, turbocharger or nitrous oxide. Used to provide more air and fuel to the engine. PSI Pounds per square inch.
This signal contains the information required for the module to output the spark at the correct time. STFT Short term fuel trims. STFTs are used at idle and part throttle. They are usually expressed as either a positive or a negative number.
A positive number means it is running too lean and the engine is adding fuel. Stoichiometric or Stoich This is the chemically correct air-fuel ratio, typically This is a measurement of the piston location in degrees of crankshaft rotation. TB Throttle Body. This is used in automatic transmissions to send transmission temperature data to the PCM.
TP Throttle Position. This is a parameter seen in Advantage software, the units used are AD counts. This sensor is attached to the throttle body and tells the PCM what the relative position of the throttle is. It is used to determine TP. Volumetric efficiency see Load, above. V olumetric Efficiency can also be called Load. This sensor is attached to the transmission and sends the PCM information on vehicle speed, which is critical for automatic transmission shifting and in speedometer operation up.

You can rename the device driver later. The supported platforms list is based on the information in the INF file of the driver. Because the accuracy of this information can vary, manually verify that the driver is supported after you import it into the catalog. After you import device drivers into the catalog, add them to driver packages or boot image packages. You can't import device drivers directly into a subfolder of the Drivers node.
To import a device driver into a subfolder, first import the device driver into the Drivers node, and then move the driver to the subfolder. Expand Operating Systems , and select the Drivers node.
Import all drivers in the following network path UNC : To import all the device drivers in a specific folder, specify its network path. Import a specific driver : To import a specific driver from a folder, specify the network path to the Windows device driver INF file. Specify the option for duplicate drivers : Select how you want Configuration Manager to manage driver categories when you import a duplicate device driver.
When you import drivers, the site server must have Read permission to the folder, or the import fails. Hide drivers that are not in a storage or network class for boot images : Use this setting to only display storage and network drivers.
This option hides other drivers that aren't typically needed for boot images, such as a video driver or modem driver. Hide drivers that are not digitally signed : Microsoft recommends only using drivers that are digitally signed. Enable these drivers and allow computers to install them : Select this setting to let computers install the device drivers. This option is enabled by default. If a device driver is causing a problem or you want to suspend the installation of a device driver, disable it during import.
You can also disable drivers after you import them. To assign the device drivers to an administrative category for filtering purposes, such as "Desktops" or "Notebooks", select Categories. Then choose an existing category, or create a new category. Use categories to control which device drivers are applied by the Auto Apply Drivers task sequence step. On the Add Driver to Packages page, choose whether to add the drivers to a package. If necessary, select New Package to create a new driver package.
When you create a new driver package, provide a network share that's not in use by other driver packages. If the package has already been distributed to distribution points, select Yes in the dialog box to update the boot images on distribution points. You can't use device drivers until they're distributed to distribution points. If you select No , run the Update Distribution Point action before using the boot image. If the driver package has never been distributed, you must use the Distribute Content action in the Driver Packages node.
On the Add Driver to Boot Images page, choose whether to add the device drivers to existing boot images. Select Yes in the dialog box to update the boot images on distribution points. Configuration Manager warns you if the architecture for one or more drivers doesn't match the architecture of the boot images that you selected.
If they don't match, select OK. Go back to the Driver Details page, and clear the drivers that don't match the architecture of the selected boot image. For example, if you select an x64 and x86 boot image, all drivers must support both architectures.
If you select an x64 boot image, all drivers must support the x64 architecture. Configuration Manager warns you if you add device drivers that aren't network or storage drivers to a boot image. In most cases, they aren't necessary for the boot image. Select Yes to add the drivers to the boot image, or No to go back and modify your driver selection.
Configuration Manager warns you if one or more of the selected drivers aren't properly digitally signed. Select Yes to continue, and select No to go back and make changes to your driver selection.
Use the following procedures to modify driver packages and boot images. To add or remove a driver, first locate it in the Drivers node. Then edit the packages or boot images with which the selected driver is associated. Expand Operating Systems , and then select the Drivers node. To add a device driver, select the check box of the driver packages to which you want to add the device drivers. To remove a device driver, clear the check box of the driver packages from which you want to remove the device driver.
If you're adding device drivers that are associated with driver packages, you can optionally create a new package. Before the drivers are available, you must update the driver package on distribution points.
You can add to boot images Windows device drivers that have been imported into the catalog. Use the following guidelines when you add device drivers to a boot image:. Add only storage and network drivers to boot images. Other types of drivers aren't usually required in Windows PE. Drivers that aren't required unnecessarily increase the size of the boot image.
Add only device drivers to a boot image for the version of Windows PE. Make sure that you use the correct device driver for the architecture of the boot image. Don't add an x86 device driver to an x64 boot image.
On the Home tab of the ribbon, in the Driver group, select Edit , and then choose Boot images.
