7.4.2. The operations of maintenance which are carried out directly on the car
Check of the coil of ignition (with the built-in power key)
Check is carried out according to the given points of check. In case of malfunction the coil of ignition should be replaced.
Check of resistance of a secondary winding
Check resistance between conclusions of a secondary winding.
Nominal rate: 8,5–11,5 kiloohms.
Check of primary winding and power transistor
For carrying out this dough it is necessary to use an analog tester.
Connect a negative wire of a tester to the socket "1".
This test should be carried out as fast as possible (no more than 10 c) to exclude possibility of an overheat of a winding of the coil of ignition and the power transistor.
Check of high-voltage wires with the distributed resistance
Measure resistance of all high-voltage wires.
Check a condition of tips and external isolation.
Measure resistance of wires.
Limiting allowed value: No more than 19 kiloohms.
Check and cleaning of spark plugs
During a detachment of high-voltage wires from spark plugs hold a wire tip. It is forbidden to make effort directly a wire.
Remove high-voltage wires.
Turn out spark plugs.
The spark gap of iridic spark plugs is not subject to adjustment.
For cleaning of spark plugs use a cleaner of spark plugs. Time of cleaning should not exceed 20 pages. It is forbidden to use wire brushes for cleaning of candles. Thus it is possible to damage iridic and platinum electrodes.
Check size of a spark gap. If the gap exceeds allowed value, the candle should be replaced.
Nominal rate: 1,0–1,1 mm.
Limiting allowed value: 1,3 mm.
During check of spark plugs do not allow hit in cylinders of extraneous particles.
Clear wells under installation of spark plugs.
Screw spark plugs.
Check of the sensor of provision of a camshaft
If in memory the code of malfunction Р0340 is written down, check a condition of wires of the sensor of provision of a camshaft.
Check of the sensor of an angle of rotation of a cranked shaft
If in memory the code of malfunction Р0335 is written down, check a condition of wires of the sensor of an angle of rotation of a cranked shaft.
Check of the sensor of a detonation
If in memory the code of malfunction Р0325 is written down, check a condition of wires of the sensor of a detonation.
