Failure of the detonation sensor may indicate errors R0325 or P0330 in the self-diagnosis system or the appearance of claps in the operation of the engine. The sensor verification shall be performed as follows:
1) Disconnect the sensor connector.
(2) Measure the resistance between conclusions 2 and 3 (medium and right, if you look at the connector on the sensor side). It shall be 5 M at 20 ° C.
3) If the resistance is 0, the sensor should be replaced.
(4) Check the sensor capacity between conclusions 2 and 3. It should be equal to 800-1600 pF.
5) Check the sensor moment of delay. It must be between 16 and 28 Nm.
6) Check the sensor transaction for the edge of the cliff.
