6.5.8. Detonation sensor
The octane number deviation from norm in modern brands of gasoline can cause a detonation in the engine. A detonation sometimes call "explosion from a spark". In the absence of a detonation the sensor gives tension signal in the control unit which provides optimum installation of a corner of ignition. When the sensor of a detonation registers abnormal splashes in pressure (detonation) there is a disconnection from the control unit and the corner of an advancing of ignition decreases before disappearance of a detonation. At any failures in operation of the sensor in memory the code 52 registers.
