2.5.3.10. Detonation sensor

Low level of an entrance signal of a chain of the sensor of a detonation (P0327)

The PCM block supervises an entrance signal of the sensor of a detonation at operation of the engine. If entrance tension between conclusions 2P and 2S the PCM block – below 0,9 In, the PCM block decides that the chain of the sensor of a detonation has malfunction.

High level of an entrance signal of a chain of the sensor of a detonation (P0328)

The PCM block supervises an entrance signal of the sensor of a detonation at operation of the engine. If entrance tension between conclusions 2P and 2S the PCM block – above 4,9 In, the PCM block decides that in a chain of the sensor of a detonation there is a malfunction.

Malfunction of a chain of the sensor of position of the crankshaft (P0335)

If the PCM block does not receive entrance tension from the sensor of position of the crankshaft during 4,2 with while the mass consumption of air makes 2,0 g / with or more, the PCM block decides that the chain of the sensor of position of the crankshaft has malfunction.

Malfunction of a chain of the sensor of provision of a cam-shaft (P0340)

The PCM block supervises tension of the sensor of provision of a cam-shaft at operation of the engine. If the PCM block does not receive entrance tension from the sensor of provision of a cam-shaft while the entrance signal of the sensor of position of the crankshaft is present, he decides that the chain of provision of a cam-shaft has malfunction.
