Check and replacement of the sensor of impulses

The DME control unit receives information on number of turns of the engine from the pulse sensor being at a gear wreath behind a pulley of a maple belt of a cranked shaft. The second sensor at a head of cylinders is the sensor of recognition of the cylinder.

 CHECK

1. For check disconnect the corresponding tip at a cable plait. If necessary previously remove the inlet pipeline since to reach tips difficultly.
2. Measure by an ohmmeter resistance on contacts of tips of the corresponding sensor. If necessary replace.
Demanded value at temperature + 20°С:
Pulse sensor of a cranked shaft: 1.3 kiloohm.
Sensor of recognition of the cylinder: between contact 1 2: Max. 1 Ohm; between contact 2 and 3: more than 10 megohms.

Removal of the pulse sensor of a cranked shaft

 PERFORMANCE ORDER

1. Disconnect the tip of the pulse sensor.

2. Disconnect an oil pipeline at the VANOS control unit and close a pure stopper.

3. Disconnect a load-lifting eye of the engine. Pay attention to a cable (1) for the subsequent correct assembly.

4. Take out a sensor cable from the directing. For this purpose disconnect cable mine at clips and remove.

5. Unscrew a bolt at an asterisk of a cranked shaft and take out the sensor with a cover.


INSTALLATION

1. Insert the sensor and slightly tighten a bolt the moment of 5 Nanometers.
2. Check shchupy sensor distance from an asterisk. Demanded value: 0.7-1.3 mm.
3. Lay a connecting cable in directing that the wire did not rub about maple a belt. Join shtekerny connection.
4. Fix a load-lifting eye of the engine.
5. Fix an oil pipeline with new sealing rings at the VANOS block.

Removal of the sensor of recognition of the cylinder

 PERFORMANCE ORDER

1. Uncover the engine, address to the Section Removal and installation of the coil of ignition.

2. It is difficult to reach the sensor. Therefore at first расстыкуйте shtekerny connection at the electromagnetic valve of the VANOS block also disconnect the valve. Address to an accompanying illustration.

3. Disconnect an oil pipeline at the VANOS block and close an opening a pure stopper, cm иллюстр. 4.4.

4. Unscrew a bolt of fastening of the sensor and remove the sensor. Address to an accompanying illustration.

5. Rasstykuyte shtekerny connection of the sensor.


INSTALLATION

1. Insert the sensor. Pay attention to the provision of rubber consolidation of the sensor. If necessary replace it.
2. Fix the sensor the moment of 5 Nanometers.
3. Lay and join a sensor cable.
4. Fix an oil pipeline with new sealing rings and fix it the moment of 30 Nanometers to the VANOS block.
5. Screw the electromagnetic valve the moment of 30 Nanometers in the VANOS block. The damaged laying replace with the new. Join shtekerny connection of the valve.
6. Establish the top cover of the engine, address to the Section Removal and installation of the coil of ignition.
