A check engine light or malfunction indicator lamp (MIL), is a tell-tale that a computerized engine-management system uses to indicate a malfunction or problem with the vehicle ranging from minor (such as a loose gas cap) to serious (worn spark plugs, engine problems or a faulty oil valve, etc.).
The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).
A concept vehicle for the then upcoming Q5, this was a 2-door convertible with a 3.0 TDI engine rated at 240 PS (177 kW; 237 hp) and 500 N⋅m (369 lbf⋅ft) torque, quattro permanent four wheel drive, 8-speed automatic transmission, Copper Sunset body, LED headlights, 21-inch wheels with 265/35R21 tyres, seats with White Stone leather upholstery, MMI, 505W Bang & Olufsen sound system and ...
The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. In a diesel, the sensor will control the fuel injection.
The Q5 e-tron was revealed at the 2021 Guangzhou Auto Show as the first three-row model of the e-tron series, and the ninth model that is based on the MEB platform. While sporting a separate exterior design, dashboard design is derived from the Q4 e-tron, with a 10.25-inch digital instrument cluster and an 11.6-inch infotainment touchscreen.
The faulted, but energized, feeder can be found with a ring-type current transformer collecting all the phase wires of the circuit; only the circuit containing a fault to ground will show a net unbalanced current. To make the ground fault current easier to detect, the grounding resistor of the system may be switched between two values so that ...
The GM Instrument Cluster Settlement was a 2008 class action settlement awarded to owners of certain General Motors vehicles with allegedly defective speedometers.The settlement allows the owner or lessee to get their instrument cluster replaced under the terms of a special coverage adjustment to their factory standard warranty.
It is referred to as non-volatile memory or NVRAM because, after the system loses power, it does retain state by virtue of the CMOS battery. When the battery fails, BIOS settings are reset to their defaults. The battery can also be used to power a real time clock (RTC) and the RTC, NVRAM and battery may be integrated into a single component.
