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.
Fuel pressure regulator; Rev limiter; Wastegate control and anti-lag; Theft prevention by blocking ignition, in response to input from an immobiliser; In a camless piston engine (an experimental design not currently used in any production vehicles), the ECU has continuous control of when each of the intake and exhaust valves are opened and by ...
The electronic system also includes sensors to detect whether the vehicle is traveling downhill, and provides additional engine braking in such circumstances. [2] Multitronic also offers a number of driver-selectable fixed ratios, selectable from either the gear-lever in a sequential style, or via (optional) steering wheel-mounted fingertip ...
These sensors also fail-safe in that they either provide a level output or nothing. Systems that measure large fuel tanks (including underground storage tanks) may use the same electro-mechanical principle or may make use of a pressure sensor, [9] sometimes connected to a mercury manometer.
This is commonly referred to as gauge pressure. Boost pressure is relative to absolute pressure - as one increases or decreases, so does the other. It is a one-to-one relationship with an offset of -100 kPa for boost pressure. Thus, a MAP sensor will always read 100 kPa more than a boost sensor measuring the same conditions.
Chad Duell is leaving General Hospital with a bang.. The Jan. 6 episode of the long-running soap opera marked the beginning of the 37-year-old actor's exit storyline when his character Michael ...
Alaska holds the all-time U.S. record. The mercury plummeted to 80 degrees below zero on Jan. 23, 1971, in Prospect Creek, north of Fairbanks.
