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

Before starting removal of the oxygen sensor, wait complete cooling of the engine.

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

Sensors of a detonation are used not on all models, and only on the following:

   a) Civic with the D16Y5 and CVT engine;
   b) Civic with the D16Y8 engine;
   c) Integra with engines B18C1 and В18С5.

Check

 PERFORMANCE ORDER

1. Disunite its electric socket of the sensor of a detonation and turn out the last from the engine (see an accompanying illustration). 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 an alternating current. Negative щуп a measuring instrument connect 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 tension fluctuations, it is necessary to replace the sensor.


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

Replacement

 PERFORMANCE ORDER

1. The sensor of a detonation will screw in the canal of an okhladitelny path of the block of the engine (see an illustration above) and its reversing is connected with certain losses of cooling liquid, to avoid which it is possible beforehand having emptied the block (see. Head Routine maintenance). Disunite the electric socket and turn out the sensor from the engine.
2. New sensors are usually delivered with the carving part covered with anti-taking hermetic. Screw the replaceable sensor on a regular place and tighten it with demanded effort. Connect to the sensor electroconducting and fill cooling system (see. Head Routine maintenance). Check the engine on existence of signs of leakages of cooling liquid.

The tightening of the sensor of a detonation with excessive effort can lead to an irreversible exit it out of operation.
