3.3.6.8. Sensors of system of ignition

GENERAL INFORMATION

Sensors of an angle of rotation and speed of rotation of the crankshaft of Motronic system of early release

the socket A – sensors of an angle of rotation

the socket B – sensors of speed of rotation of the crankshaft

 1–cover of a head of cylinders

Sensors of an angle of rotation and speed of rotation of the crankshaft of Motronic system of late release

the socket A – sensors of an angle of rotation

the socket B – sensors of speed of rotation of the crankshaft

 1–starter

Check and replacement

PERFORMANCE ORDER
Sensors of an angle of rotation and speed of rotation of the crankshaft
1. Measure resistance between conclusions 1 (a yellow wire) and 2 (a black wire) from the sensor which should be 860–1060 Ohm.
2. Measure resistance between conclusions 3 and 2 or 1 which 100 kiloohms should be.
3. If resistance differs, replace the sensor (and).
4. For replacement unscrew screws and get sensors from nests. Consider that the place of the sensor of an angle of rotation is noted by a letter In, and a place of the sensor of speed of rotation – a letter of D.
Incorporated sensor of impulses of rotation of the crankshaft (late models)
5. Disconnect sockets.
6. Measure resistance between conclusions 1 (a yellow wire) and 2 (a black wire) from the sensor on each socket which should be 500–600 Ohm.

7. If resistance differs, replace the sensor.
8. For replacement unscrew a bolt (the sensor fastens on a cover of a gear belt near a pulley).

9. Get the sensor and replace. The gap (3) between a head of the sensor (1) and a rotor (2) should be 1,0±0,3 mm. At replacement expose a gap brass the shchupy.
