Installation site of the sensor of an angle of rotation of the crankshaft

On some cars of the last years of release the sensor of an angle of rotation of the crankshaft (it is specified by an arrow) is about a cover of a gear belt, near a pulley. The sensor gives a signal in the control unit on the basis of which the crankshaft angle of rotation precisely is defined.


1. Measure crankshaft sensor resistance. It has to be within 1,630–3,225 Ohms depending on temperature: at temperature increase resistance of the sensor increases. If the measured values of resistance do not correspond to this range, replace the sensor.
2. For replacement of the sensor remove a pulley (see subsection, disconnect the socket and turn out screws of fastening of the sensor.
3. Installation of the sensor is carried out upside-down.
