Check of serviceability of a state and replacement of the sensor of a detonation

Sensors of a detonation react to increase of intensity of vibrations of the engine, usually caused by a detonation of air and fuel mix. On the basis of information of RSM received from the sensor corrects the ignition advancing moment, trying to support him at the greatest possible level guaranteeing sufficient efficiency of return of the engine. The sensor develops a signal of alternating current which amplitude increases in proportion to the level of vibrations. For compensation of detonations of RSM if necessary gives out team for moving of the moment of ignition towards delay.

CHECK

 PERFORMANCE ORDER

Disunite its electric socket of the sensor of detonations and lower from the engine cooling liquid (see the Head Nastroyki and routine maintenance). Turn out the sensor of detonations from the engine block. Again connect the socket to the sensor. Check of sensors of this type is made by registration of fluctuations of tension on the voltmeter. Switch the device to a scale of a low voltage of alternating current. Connect the negative probe of the measuring instrument to the sensor case, positive - to the contact plug. Slightly knock on the lower part of the sensor with a hammer, feigning vibration. If the voltmeter does not register fluctuations of tension, the sensor should be replaced.

In principle this check can be made and without removal of the sensor from the engine.

REPLACEMENT

 PERFORMANCE ORDER

Before starting procedure performance, wait for full cooling of the engine.

1. Disconnect a negative wire from the battery.

If the stereosystem established on the car is equipped with a security code before disconnecting the battery make sure that have the correct combination for input of the audio system in action!

2. The sensor of a detonation will be screwed in the canal of a cooling path of the block of the engine and its reversing is connected with certain losses of cooling liquid, to avoid which it is possible beforehand having emptied the block (see the Head Nastroyki and routine maintenance). Disunite the electric socket and turn out the sensor from the engine.

3. New sensors are usually delivered with the carving part covered with the anti-taking sealant. Screw the replaceable sensor on a regular place and tighten it with the demanded effort (about 19 Nanometers).

The detonation sensor tightening with excessive effort can lead to an irreversible exit it out of operation. Connect an electrical wiring to the sensor and fill the cooling system (see the Head Nastroyki and routine maintenance). Check the engine for existence of signs of leak of cooling liquid.
