The sensor of a detonation defines a detonation in cylinders of the engine and transmits the operating signal to the ESM block which reduces an ignition advancing corner by the size excluding a detonation in engine cylinders.
PERFORMANCE ORDER
1. Sensors of a detonation are located under an inlet collector. For access to sensors of a detonation it is necessary to remove a chamber of an air inlet and an inlet collector.
2. Using an ohmmeter, check that there is no contact between contacts of the sensor of a detonation and the engine.
