Check of a condition and replacement of the sensor of provision of a cranked shaft (SKR) On models since 1995 вып. two SKR sensors, one of which (REF sensor) are used is established in a forward part of the power unit, on aluminum section of the pallet of a case of the engine, is direct under a pulley of a cranked shaft. Also serves for definition of quantity of grooves of the rotor sensor of a pulley of a cranked shaft in relation to positions VMT of the piston of each of cylinders (a signal 120 °). The second sensor (POS) also is on aluminum section of the pallet, but from the back party of the power unit, near a dome of transmission and serves for determination of frequency of rotation of a shaft (a signal 1 °). Both sensors consist of a constant magnet, the core and a wire winding. Change of a gap involves change of parameters of a magnetic field in close proximity to the sensor that, in turn leads to change of amplitude given out by the sensor on RSM of alarm tension. RSM uses information arriving from SKR sensors at corrections of installations of a corner of an advancing of ignition, synchronization of injection and detection of admissions of ignition.
