OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
The MAP sensor is then used for rationality checks and to test the EGR valve. The way they do this is during a deceleration of the vehicle when there is low absolute pressure in the intake manifold (i.e., a high vacuum present in the intake manifold relative to the outside air) the powertrain control module (PCM) will open the EGR valve and ...

In many venturis, the column on the left has fluid in it (>), while only the column on the right is a siphon (<). If p < 0 {\displaystyle p<0} and g < 0 {\displaystyle g<0} , we observe that the pressure head is again positive, predicting that the venturi meter shown above would look the same, only upside down.
Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...
While it might seem like a celery stalk refers to a single piece of celery, the term actually refers to the entire bunch, including all the individual ribs, as well as the leafy tops.
Cold inflation pressure is a gauge pressure and not an absolute pressure. This article focuses on cold inflation pressures for passenger vehicles and trucks. The general principles are, of course, applicable to bicycle tires, tractor tires, and any other kind of tire with an internal structure that gives it a defined size and shape (as opposed ...
